Magnetic Resonance Imaging (MRI)
Will the scan hurt?
No, patients won't feel a thing. They simply lie still during the scan.
Is it safe?
MRI technology has been available for more than 20 years and is extremely safe. Unlike X-rays, MRI does not use radiation.
How long does it take?
Depending on each situation, an MRI could take between 30 and 60 minutes.
What happens during the scan?
It's very simple:
- Patients are positioned on the scanning bed.
- An instrument called an image coil will be placed over the area examined.
- The bed (tumbrel) will then be moved into the scanning chamber.
- Patients will be asked to lie very still during the scan.
- A doctor may request that a patient receive an injection of contrast agent to provide additional information about the area being scanned. The injection feels like any other shot, and is very safe.
- During the scan, patients may hear a chirping sound from the scanner. This is normal.
Can anyone have an MRI?
Since MRI is very safe, most people can have a scan done. However, if a patient has a pacemaker or metal implant, or if they are a woman in their first trimester of pregnancy, they cannot be scanned.
When will patients get the results?
A radiologist will read a patient’s scan and send a report to their physician within 24 hours. Their doctor will contact them to discuss their results.
Will insurance cover an MRI?
Most insurance plans cover MRI. Patients should contact their insurance plan if they have any questions.
How should a patient prepare for their scan?
- Patients should arrive 30 minutes before their scheduled appointment and go to the Registration Department.
- Patients should dress in warm, comfortable clothing (sweatshirt and pants work well).
- Patients cannot wear anything metallic during the exam, so it's best for them to leave watches, jewelry or anything else containing metal at home.
- If sedation is ordered, a doctor will provide further instructions.
