An MRI scanner creates three dimensional images of body tissues using a large magnet and radio waves. It does not use radiation. There are no known harmful effects from having an MRI scan.
How is the test done?
You will go out to a mobile MRI unit that is on a truck. The magnet is always on the room. Due to the strength of the magnetic field all metal objects such as barrettes, bobby pins, jewelry and credit cards must be used to give more information about your body. If contrast is needed, an IV will be started in the arm or hand by the MRI technologist. The scanning machine is large with an opening in the middle. You will be lying on the imaging bed, which moves in and out of the opening smoothly. A coil will be placed over the part of the body being scanned. The scanner will not touch you. It makes a loud thumping or tapping sounds. You will be given earplugs to wear. You must hold very still during the test.
What to expect after the test?
If IV contrast was injected, drink plenty of water after the test to help flush it through the kidneys. The ordering doctor will contact you with results within a few days.
MRI is provided by Shared Medical Services (SMS) out of Cottage Grove, WI.
Approximate time of each scan is 45minutes.
