MRI (1.0 T Open, 1.5 T and 3T)
What is the procedure?
MRI stands for Magnetic Resonance Imaging. The test uses a magnetic field in conjunction with a radiofrequency pulse to obtain pictures of the vessels and organs of the body.
If necessary to obtain better images, an injection of gadolinium may be administered by either the nurse or the doctor.
People with pacemakers cannot have an MRI, as the magnet in the machine could disrupt the function of the pacemaker. If you have stents, screws, nails, shrapnel, bullets, tattoos, IUDs, hearing aids, staples, or any other metal in your body, please inform the technologist.
For claustrophobic patients, we offer an open MRI machine that is wider and open at the sides. Some patients find it beneficial to take a sedative, such as Valium, before the exam. Speak to your doctor about this option, and be sure to bring someone to drive you home.
The day of the exam:
There is no preparation for an MRI exam. However, the technologist will tell you what clothing and accessories to remove, such as hearing aids, watches, hairpins, and jewelry.
During the exam:
The MRI takes about 30 minutes without the injection, and about an 45 Minutes with it. During the exam, you will lie on the table with the targeted area directly under the magnet. You must hold still at certain times although the machine may move in and out. The technologist will watch from a window at all times, and will use an intercom to speak with you.
After the exam:
Call your referring physician for results, which are generally available within 24 hours.
