Steam Error Code E87: Causes, Fixes, and Prevention

Published

on

steam error code e87

Millions of players worldwide rely on Steam as their go-to platform for gaming, but occasionally, login issues disrupt the experience. One such frustrating issue is Steam Error Code E87, a problem that prevents users from signing in and enjoying their favorite titles. While the error may seem alarming at first, it is usually linked to account authentication failures, server issues, or client-side problems that can be fixed with a few simple steps.

Understanding the Nature of the Error

This login problem often arises when Steam’s authentication servers cannot validate your credentials properly. Instead of letting you in, the client shows an error message and blocks access. Unlike game-specific crashes, this is a platform-level obstacle that requires troubleshooting related to your account, network, or client software.

In many cases, the issue is temporary and tied to Steam servers being overloaded. However, for persistent errors, the causes often include misconfigured Windows Firewall settings, incorrect date and time synchronization, cached data conflicts, or attempting to log in with an email instead of a username.

Common Reasons Why the Error Occurs

1. Server-Side Disruptions

When Steam servers are under maintenance or experiencing outages, users often face login failures. This means the problem isn’t with your PC or internet, but with the platform itself. Checking the official server status page is the best way to confirm whether the issue is widespread.

2. Login Credential Confusion

Many users mistakenly enter their email addresses instead of their usernames. While Steam allows email use in some contexts, error E87 is commonly linked with authentication mismatches. Entering your registered username is a safer option.

3. Date and Time Mismatch

An often-overlooked factor is the system clock. If your Windows date, time, or timezone are out of sync, Steam’s authentication request may fail because of invalid certificates. This small misconfiguration has caused countless login rejections across different regions.

4. Internet or Firewall Restrictions

A weak network connection, blocked ports, or restrictive VPN settings can prevent the Steam client from contacting its servers. Similarly, overly strict firewall rules may classify Steam as unsafe and disrupt the login process.

5. Cache and Temporary File Corruption

Over time, Steam accumulates temporary data such as download cache and configuration files. When these become corrupted, login requests may return errors. Clearing the cache often resolves these issues immediately.

6. Multiple Device Logins

If your account is logged in across several devices simultaneously, Steam Guard may deny new login attempts. In such cases, deauthorizing all devices and starting fresh helps restore access.

Quick Fixes to Try Immediately

Restart the Steam Client

Closing Steam completely and relaunching it is sometimes all that’s needed. This refreshes your connection to the servers and eliminates minor glitches.

Use Username Instead of Email

Always enter your username rather than your email when signing in. This simple adjustment often bypasses the error entirely.

Sync Date and Time

Enable automatic time synchronization in Windows settings. A properly aligned system clock prevents certificate mismatches that block logins.

Check Server Status

Visit Steam’s official status page or community forums. If the issue is global, waiting until maintenance concludes is the only solution.

Advanced Troubleshooting for Persistent Issues

Disable Firewall or VPN Temporarily

If your firewall or VPN is interfering, disable it for a short time and attempt to log in again. Be sure to re-enable security tools afterward.

Run Steam as Administrator

Launching the client with administrative privileges ensures that Windows does not restrict access to required system resources.

Clear Download Cache

In the Steam client, go to Settings > Downloads > Clear Download Cache. This forces Steam to rebuild temporary data and often eliminates corrupted entries.

Repair Steam Installation

Running Steam with the /repair command line argument fixes damaged core files. This method is especially effective when the client itself is faulty.

Deauthorize All Devices

From your Steam Guard settings, revoke access to all connected devices. Afterward, log in again with your primary computer to reset session data.

Use QR Code Login

Steam mobile app allows QR-based login, bypassing traditional credential entry. This method often succeeds when manual login fails due to authentication conflicts.

When to Contact Steam Support

If none of the above solutions work, it may be time to reach out to Steam Support. Provide them with details such as your username (not password), system specifications, and troubleshooting steps already attempted. Additionally, avoid repeated login attempts, as this may temporarily lock your account.

Preventing Future Login Errors

  • Always use your username for sign-ins.
  • Keep system date and time set to automatic.
  • Regularly clear Steam’s download cache.
  • Ensure Windows Firewall allows Steam through.
  • Keep your Steam client updated.
  • Avoid excessive login attempts across multiple devices.

By practicing these preventive measures, you can minimize the risk of encountering similar errors in the future.

FAQs

What does Steam error code E87 mean?

It is a login error that indicates Steam servers could not authenticate your credentials properly. This usually results from server issues, wrong login methods, or client-side problems.

Can using my email instead of my username cause E87?

Yes, many users report the error appearing when they attempt to log in with their email address instead of their actual username.

Does clearing the Steam download cache fix the problem?

In many cases, yes. Corrupted cache files interfere with authentication, and clearing them refreshes the login process.

Can incorrect date and time settings trigger the error?

Absolutely. If your system clock is out of sync with Steam servers, certificate verification may fail, resulting in the error.

Should I disable my VPN or firewall to solve the issue?

Disabling them temporarily can help. Firewalls and VPNs sometimes block Steam’s communication with its servers, causing login failures.

Is contacting Steam Support necessary for this error?

Most users solve it on their own, but if the problem persists after trying all fixes, contacting Steam Support is the best option.

Conclusion

Steam Error Code E87 may feel frustrating, but it’s rarely a sign of a serious problem. The issue usually stems from incorrect login practices, temporary server outages, firewall restrictions, or corrupted cache files. By following a structured troubleshooting process—starting with simple steps like checking server status and syncing your system clock, and moving toward advanced fixes like clearing cache or repairing the client—you can resolve the error effectively. With the right preventive habits, you’ll reduce the likelihood of facing this obstacle again, ensuring a smoother gaming experience on Steam.

Diagnostic Imaging: A Complete Guide to X-Ray, MRI, CT Scan & Ultrasound

Published

on

Diagnostic Imaging

Diagnostic imaging also known as medical imaging refers to a range of techniques and processes used to create visual representations of the interior of the human body. These images allow physicians to examine organs, bones, blood vessels, and tissues to detect disease, monitor ongoing conditions, and plan treatments, often without requiring invasive procedures.

Modern diagnostic imaging sits at the intersection of physics, biology, and computer science. Depending on the modality (the specific type of scan), images may be produced using ionizing radiation (X-rays and CT scans), magnetic fields and radio waves (MRI), high-frequency sound waves (ultrasound), or radioactive tracers (PET scans). Each technology has its own strengths, limitations, and ideal use cases.

The images produced are reviewed and interpreted by a radiologist a specialist physician trained to read and report on medical images. The radiologist’s report is then used by your referring doctor to make decisions about your diagnosis and treatment.

The Main Types of Diagnostic Imaging

There are several primary imaging modalities in use today. Each serves a distinct clinical purpose, and understanding the differences can help you feel more informed and less anxious when your doctor recommends a scan.

X-Ray (Radiography)

X-ray is the oldest and most widely used form of medical imaging. It works by passing a small amount of ionizing radiation through the body. Dense structures such as bones absorb radiation and appear white on the image, while softer tissues appear in shades of grey, and air-filled spaces (like the lungs) appear dark.

X-rays are fast, painless, and relatively inexpensive, making them the go-to imaging tool in emergency rooms and primary care settings.

Common uses include:

  • Detecting fractures, dislocations, and bone abnormalities
  • Diagnosing pneumonia, collapsed lung, or chest infections
  • Monitoring bone density and joint conditions such as arthritis
  • Identifying foreign objects in the body
  • Screening for lung cancer (low-dose CT is now preferred for this)

Radiation dose: Very low. A standard chest X-ray exposes you to approximately the same amount of radiation you would receive from a few hours of natural background radiation.

Computed Tomography (CT Scan)

A CT scan (also called a CAT scan) takes multiple X-ray images from different angles around your body and uses a computer to reconstruct them into detailed cross-sectional images essentially a 3D map of your internal structures. This makes CT scans far more detailed than a standard X-ray, particularly for soft tissues, blood vessels, and complex anatomy.

CT scans are commonly ordered in emergency situations because they are fast and comprehensive. They are also widely used in cancer staging, trauma assessment, and pre-surgical planning.

A contrast dye (contrast material) may be injected into your vein or taken orally before the scan to make certain structures, such as blood vessels or tumors, more visible on the images.

Common uses include:

  • Detecting internal bleeding and organ injuries after trauma
  • Diagnosing cancer and monitoring treatment response
  • Evaluating blood vessels (CT angiography)
  • Identifying appendicitis, kidney stones, and bowel obstructions
  • Guiding biopsies and other minimally invasive procedures

Radiation dose: Moderate. Higher than a standard X-ray, but still within acceptable safety limits for most patients. Your radiologist and referring doctor weigh the diagnostic benefit against the risk before ordering a CT scan.

Magnetic Resonance Imaging (MRI)

MRI uses a powerful magnetic field and radio waves not radiation to create detailed images of soft tissues, organs, and the nervous system. It is particularly valuable for imaging the brain, spinal cord, joints, ligaments, muscles, and pelvic organs, where it provides far greater soft-tissue contrast than CT or X-ray.

Because MRI does not use ionizing radiation, it is a preferred imaging method for patients who require repeated imaging, pregnant women (especially after the first trimester), and children.

MRI scans are longer than other types of scans, typically taking 30 to 90 minutes. The scanner produces loud knocking and thumping noises, and patients are given ear protection. Some patients experience claustrophobia; if this is a concern, an open MRI machine or mild sedation may be offered.

Important: Because of the powerful magnetic field, all metal implants must be declared before the scan. Pacemakers, cochlear implants, and certain types of metal clips may be contraindications for MRI. Always inform your radiographer of any implants or metal in your body.

Common uses include:

  • Brain and spinal cord imaging (strokes, MS, tumors, disc herniation)
  • Joint imaging (torn ligaments, cartilage damage, meniscus tears)
  • Breast MRI for high-risk cancer screening
  • Pelvic imaging (uterus, ovaries, prostate)
  • Cardiac MRI for heart structure and function

Ultrasound (Sonography)

Ultrasound imaging uses high-frequency sound waves transmitted through a handheld probe (transducer) placed on the skin. The sound waves bounce off internal structures, and a computer converts the returning echoes into a real-time image on a screen.

Ultrasound is unique in that it produces live, moving images making it ideal for examining blood flow (Doppler ultrasound), assessing fetal development during pregnancy, and guiding needle biopsies. It involves no radiation and is widely considered safe for all patients, including pregnant women and newborns.

Common uses include:

  • Obstetric imaging monitoring fetal growth and development
  • Abdominal imaging gallbladder stones, liver disease, kidney abnormalities
  • Vascular imaging detecting blood clots, arterial stenosis (Doppler)
  • Breast ultrasound distinguishing cysts from solid masses
  • Guiding biopsies, drain placements, and injections

Limitation: Ultrasound does not produce as detailed images as CT or MRI for deep structures, and image quality can be affected by factors such as body composition and the presence of gas in the bowel.

PET Scan (Positron Emission Tomography)

A PET scan is a form of nuclear medicine imaging that shows how organs and tissues are functioning at a cellular level, rather than simply showing their structure. Before the scan, a small amount of a radioactive tracer (usually a glucose-based compound) is injected into a vein. Cells that are metabolically active such as cancer cells absorb more of the tracer and appear as bright spots on the scan.

PET scans are often combined with CT or MRI (PET-CT or PET-MRI) to provide both functional and structural information in a single session.

Common uses include:

  • Cancer diagnosis, staging, and monitoring treatment response
  • Evaluating brain function in Alzheimer’s disease, epilepsy, and brain tumors
  • Assessing heart muscle viability before cardiac procedures

Quick Comparison: Diagnostic Imaging at a Glance

Use the table below to understand the key differences between imaging types at a glance.

Imaging TypeUses Radiation?Best ForTypical Duration
X-RayYes (Low)Bones, Chest, Lungs5–15 minutes
CT ScanYes (Moderate)Internal injuries, Cancer10–30 minutes
MRINoBrain, Spine, Soft Tissue30–90 minutes
UltrasoundNoPregnancy, Abdomen, Vascular20–45 minutes
PET ScanYes (Tracer)Cancer staging, Brain activity2–4 hours

How to Prepare for Your Diagnostic Imaging Scan

Preparation varies depending on the type of scan. Below is a practical checklist for each modality. Your imaging center will also provide specific instructions when you book your appointment always follow their guidance, as protocols can differ.

X-Ray Preparation

  • Remove jewellery, piercings, and metal accessories from the area being scanned
  • Inform staff if you are pregnant or could be pregnant
  • Wear comfortable, loose-fitting clothing you may be asked to change into a gown
  • No fasting required (unless combined with another procedure)

CT Scan Preparation

  • Do not eat or drink for 4 hours before the scan if contrast dye is being used
  • Inform the radiographer of any allergies particularly to iodine or shellfish (relevant to contrast reactions)
  • Inform staff if you have kidney problems (contrast dye requires adequate kidney function)
  • Remove metal jewellery and accessories
  • Inform staff if you are pregnant

MRI Preparation

  • Complete a metal screening questionnaire declare all implants, surgical clips, and any metal in or on your body
  • Remove all metal objects including piercings, watch, hearing aids, and hairpins
  • Inform staff of any pacemaker, cochlear implant, neurostimulator, or metal joint replacement
  • Wear comfortable, metal-free clothing or change into a provided gown
  • Fasting is generally not required unless abdominal contrast MRI is being performed
  • If you experience claustrophobia, inform your doctor in advance open MRI or mild sedation may be available

Abdominal Ultrasound Preparation

  • Fast (nothing to eat or drink) for 6–8 hours before the scan this ensures the gallbladder is full and the bowel contains minimal gas
  • Take prescribed medications with a small sip of water only
  • Avoid chewing gum, as it produces air in the stomach

Pelvic Ultrasound Preparation

  • Drink approximately 1 litre of water 1 hour before the scan and do not empty your bladder a full bladder is required for optimal imaging of the uterus and ovaries
  • You may be told to empty your bladder for the second part of the scan (transvaginal ultrasound, if performed)

Benefits vs Risks: What You Need to Know

The Benefits of Diagnostic Imaging

Diagnostic imaging has revolutionised the way medicine is practised. Its key benefits include:

  • Early detection: Imaging can identify disease at its earliest stages before symptoms appear significantly improving treatment outcomes, particularly in cancer.
  • Accurate diagnosis: Imaging provides objective, visual evidence that supports or confirms a clinical diagnosis, reducing the likelihood of misdiagnosis.
  • Non-invasive: Most imaging modalities require no incisions, injections (with the exception of contrast-enhanced scans), or recovery time.
  • Treatment planning: Surgeons use imaging to plan operations, interventional radiologists use it to guide procedures, and oncologists use it to target radiation therapy precisely.
  • Monitoring progress: Repeat imaging allows doctors to track how a condition responds to treatment, whether it is chemotherapy, physiotherapy, or medication.

Understanding the Risks

While diagnostic imaging is generally very safe, it is important to understand the associated risks for informed decision-making.

Radiation exposure: X-rays and CT scans use ionizing radiation. While doses are kept as low as reasonably achievable (following the ALARA principle), repeated exposure over time carries a small cumulative risk. Your doctor will only request a radiation-based scan when the diagnostic benefit outweighs this risk.

Contrast reactions: Contrast dye used in CT and MRI scans can occasionally cause allergic reactions. Mild reactions (flushing, nausea) are relatively common; severe anaphylactic reactions are rare but possible. Patients with known allergies or kidney problems should always inform their medical team.

MRI and implants: The magnetic field used in MRI can interact with certain metal implants or devices, potentially causing movement, heating, or malfunction. Thorough screening before every MRI scan is essential.

Pregnancy considerations: Ionising radiation should be avoided during pregnancy where possible, particularly in the first trimester. Ultrasound and MRI (after the first trimester) are generally considered safe alternatives.

Frequently Asked Questions

What is the difference between an MRI and a CT scan?

Both MRI and CT scans produce detailed cross-sectional images of the body, but they work differently. CT uses X-ray radiation and is faster and better suited for dense structures, trauma, and emergencies. MRI uses magnetic fields and radio waves (no radiation) and provides superior detail of soft tissues such as the brain, spinal cord, and joints. Your doctor will choose the most appropriate scan based on what they need to evaluate.

Does a CT scan use more radiation than an X-ray?

Yes. A CT scan uses significantly more radiation than a standard X-ray because it captures hundreds of cross-sectional images from multiple angles. However, the radiation dose is still within safe medical limits and is justified by the far greater diagnostic detail it provides. Your imaging team follows strict protocols to minimise your exposure.

Can I eat or drink before an ultrasound?

It depends on the type of ultrasound. For an abdominal ultrasound (examining the liver, gallbladder, pancreas, and kidneys), you will usually need to fast for 6–8 hours beforehand. For a pelvic ultrasound, you will need to have a full bladder. For other types such as a thyroid or vascular ultrasound no preparation is usually required. Your imaging centre will give you specific instructions when you book.

How long does an MRI take?

Most MRI scans take between 30 and 90 minutes, depending on the body area being scanned and whether contrast is used. You must remain very still inside the scanner throughout. The machine is loud you will be given earplugs or headphones. If you feel anxious or claustrophobic, inform the radiographer before the scan begins; they can pause the scan or adjust the pace if needed.

Is diagnostic imaging painful?

In most cases, no. The scans themselves are painless. You may experience mild discomfort from lying still for an extended period during an MRI, or a brief warm or flushing sensation when contrast dye is injected for a CT scan. Biopsy procedures guided by imaging involve local anaesthetic and may cause some discomfort.

Why do I need contrast dye?

Contrast material (dye) is used in some CT and MRI scans to make certain structures such as blood vessels, tumours, and areas of inflammation more visible. Without contrast, these features may be difficult to distinguish from surrounding tissue. Your doctor or radiologist will request contrast when it will meaningfully improve the diagnostic quality of the scan.

Can I have an MRI if I have a pacemaker?

Many modern pacemakers are now MRI-conditional, meaning they can be safely scanned under specific conditions and with specialist supervision. However, older devices may not be compatible. You should always inform your doctor and the imaging centre about your pacemaker before any MRI is arranged. The imaging team will verify the device model and consult with your cardiologist if necessary.

How much does a diagnostic imaging scan cost?

Costs vary widely depending on the type of scan, location, and whether you are covered by insurance. In the United States, an X-ray typically costs between $100 and $1,000 without insurance; a CT scan between $500 and $3,000; and an MRI between $400 and $12,000 depending on the area of the body. Many scans are covered partially or fully by health insurance if medically necessary. Always check with your insurance provider before your appointment, and ask your imaging centre about self-pay discounts.

What should I wear to my imaging appointment?

Wear comfortable, loose-fitting clothes without metal zippers, underwire, or metal fastenings particularly for MRI. You may be asked to change into a hospital gown. Leave jewellery and accessories at home whenever possible. For MRI specifically, wear clothing you do not mind potentially being asked to remove, as any metal items must be taken off before entering the scanner room.

Finding a Qualified Imaging Centre

Not all imaging facilities are created equal. When choosing where to have your scan, look for the following quality indicators:

  • ACR Accreditation: The American College of Radiology (ACR) accredits imaging facilities that meet rigorous standards for equipment, safety, and the qualifications of staff. Look for the ACR gold seal on any facility’s website.
  • IAC Accreditation: For ultrasound and vascular testing, accreditation from the Intersocietal Accreditation Commission (IAC) is a mark of quality.
  • Board-certified radiologists: Ensure that a qualified, board-certified radiologist will read and report on your scan. Teleradiology is common, but reports should always be reviewed by a physician.
  • Modern equipment: Ask whether the facility uses up-to-date, well-maintained equipment. Older scanners may produce lower-quality images.
  • Outpatient imaging centres vs. hospitals: Hospital radiology departments and dedicated outpatient imaging centres both offer high-quality scans. Outpatient centres often have shorter waiting times and lower costs. Your GP or specialist can recommend a reputable facility in your area.

Conclusion

Diagnostic imaging is one of the most powerful tools in modern medicine. From the speed of an emergency X-ray to the extraordinary detail of a brain MRI, imaging technologies give clinicians the ability to diagnose faster, plan more precisely, and monitor treatment with unparalleled accuracy.

If your doctor has recommended an imaging scan, it is natural to have questions and perhaps some anxiety. Understanding what the scan is, why it has been ordered, and how to prepare can make a significant difference to your experience. The imaging team from the radiographer who performs the scan to the radiologist who interprets it is there to support you throughout the process.

Always consult your doctor if you have concerns about a recommended scan. And if you have been waiting for imaging you believe is necessary, do not hesitate to raise it at your next appointment. Early, accurate imaging can be life-changing.
