Common MRI Myths Debunked: Fact vs Fiction

MRI is one of the safest and most powerful diagnostic tools in medicine. Yet many patients feel anxious about their scan because of myths and misconceptions they have heard from friends, family, or the internet.

Let us separate fact from fiction so you can feel confident about your MRI at Advanced Medical Imaging.

Myth 1: MRI Uses Dangerous Radiation

Fact: MRI uses zero radiation. Unlike CT scans and X-rays, MRI creates images using a magnetic field and radio waves — the same types of energy used in radio broadcasts and cell phones. The FDA confirms that MRI does not expose patients to ionizing radiation.

This makes MRI particularly useful for patients who need repeated imaging over time, such as cancer surveillance or chronic condition monitoring.

Myth 2: MRI Is Painful

Fact: MRI is completely painless. You lie still on a cushioned table while the machine takes pictures. You will not feel the magnetic field or the radio waves. The only sensation some patients notice is mild warmth in the area being scanned, which is normal.

If you are having an MRI with contrast, you will feel a brief pinch from the IV needle. The contrast injection itself is painless, though some people feel a temporary warm flush.

Myth 3: You Cannot Get an MRI If You Are Claustrophobic

Fact: Claustrophobia is common but manageable. At AMI, we offer several solutions:

• Open MRI — our open system is much less confining than a traditional closed MRI
• Music and headphones — listen to your favorite station during the exam
• Communication — you can talk to your technologist throughout the scan and have a squeeze ball to signal for a break
• Mild sedation — your doctor can prescribe anti-anxiety medication to take before the exam
• Coaching — our technologists are experienced at helping anxious patients feel comfortable

Many patients who thought they could not tolerate an MRI complete their scans successfully with these strategies.

Myth 4: All Metal Implants Mean You Cannot Have an MRI

Fact: Some metal implants are not MRI-safe, but many are. Modern joint replacements, most dental implants, and many surgical clips and screws are made from MRI-compatible materials.

What matters is the type of metal and when it was implanted. Before your scan, you will complete a detailed screening questionnaire. Our technologists will review your specific implants and check manufacturer safety data.

Implants that are generally not MRI-safe include: - Certain older pacemakers and defibrillators (though many newer ones are MRI-conditional) - Some cochlear implants - Metallic foreign bodies (especially near the eyes) - Certain brain aneurysm clips

The American College of Radiology maintains comprehensive safety guidelines for implants and MRI.

Myth 5: MRI Contrast Dye Is Dangerous

Fact: MRI contrast (gadolinium) is very safe for the vast majority of patients. Allergic reactions are rare — occurring in less than 1% of patients — and serious reactions are extremely uncommon.

The main concern is for patients with severe kidney disease, as gadolinium can rarely cause a condition called nephrogenic systemic fibrosis (NSF). This is why we ask about your kidney function before administering contrast. If your kidneys are healthy, the contrast is processed and eliminated from your body within hours.

Not all MRI exams require contrast — your doctor will decide based on what they need to see.

Myth 6: MRI Takes Hours

Fact: Most MRI exams take 30 to 60 minutes. Some focused scans (a single joint, for example) can be completed in 20 minutes. We tell you the expected duration when you schedule so you can plan your day.

Myth 7: You Will Be Alone During the Scan

Fact: Your technologist is watching you the entire time through a window and on camera. You can communicate through the intercom at any point. You are never truly alone in the MRI suite.

Myth 8: MRI Results Take Weeks

Fact: At AMI, our board-certified radiologists typically review and report your MRI results within 24 to 48 hours. Your referring physician receives the report promptly so treatment decisions are not delayed.
