What happens during the examination

Magnetic resonance imaging (MRI) uses strong magnetic field and radiofrequency energy to make pictures. MRI does not rely on the X-rays. MRI exam is painless and causes no known tissue damages of any kind.

MRI scanner is a long tube-like machine. The tube is well illuminated and ventilated. Your body part to be examined is placed in the center of the tube. The staff will monitor you constantly from outside of the examination room. During the examination you are able to contact the staff if needed.

MRI examination takes usually 20-60 minutes. You will be asked to remain perfectly still during the imaging. We try to make you feel as comfortable as possible. You may be asked to hold your breath for a few seconds.

The machine will make a loud noise while the images are taken. You will be given a hearing protector. Often you can listen to the radio. F

or some MRI studies, a contrast agent (gadolinium) may be injected into a vein or in a joint to help obtain a clearer image of the area being examined. MRI contrast agents do not contain iodine.

After the examination

Examinations need no after-treatment. If you were given contrast medicine, the cannula will be taken off.

A radiologist, a specially trained physician, will examine your images and the interpretation of the results will be sent to your doctor. Your doctor will share the results with you.
