❓ Frequently Asked Questions
What is an MRI machine used for?
An MRI machine is used to create detailed images of the body’s internal structures, especially soft tissues like the brain, muscles, ligaments, and organs.
How does MRI differ from CT scans?
MRI uses strong magnets and radio waves to produce images, while CT scans use X-rays. MRI typically involves no ionizing radiation.
What happens during an MRI scan?
You lie still on a table that slides into the MRI scanner. The machine uses magnets and radio-frequency signals to capture images, often making loud tapping or knocking sounds.
Are MRI scans safe for everyone?
MRI may be unsafe for some people with certain metal implants or devices. It’s important to disclose any implants, prior surgeries, or metal fragments before the scan.
Why do some people receive a contrast agent for MRI?
A contrast agent (often based on gadolinium) can help highlight specific tissues or blood vessels, improving the clarity of certain findings as directed by the clinician.
