How do I prepare for an MRI
Several days prior to your MRI, you need to contact AMI MRI Department to go over a screening questionnaire, 860-489-2982. During the screening process, safety questions will be asked regarding past metal injuries, recent surgeries within the last 6 weeks or prior surgery for placement of a pacemaker, aneurysm clips, metallic implants or a defibrillator, etc. Certain MRI exams will require you to fast for up to four hours prior to the exam and the schedulers will instruct you regarding the necessity for doing so.
Please print and fill out the MRI screening form before your appointment.
If you feel you may have difficulty lying still in a confined space, you may want to ask your referring physician for a prescription for a sedative to be taken just before your exam. Patients should prepare for their MRI exam by wearing comfortable clothing without any metal buttons, zippers.
The technologist will make sure that you do not have any metal on your body before the procedure begins. It is very important to remain still during the test. Most exams take 30-60 minutes, depending on the type of exam. Some patients will require an injection of contrast material to enhance the visibility of certain tissues or blood vessels. The injection is given with a small needle in a vein in the arm or hand. This should have no effect on how you feel after the exam.

Coronary Calcium scoring is not for everyone. In general, it is most appropriate for men and women, age 40-70, who have one additional risk factor. It is not for people with already known coronary heart disease, arrhythmia’s, or previous heart surgery. The scan could be the first step in preventing a major fatal cardiac event.

There is no specific preparation for the scan. You may eat or drink, however caffeinated products may make your heart beat too fast. Avoid shirts with metal straps or buttons. Women should avoid wearing a bra with under-wire or metal closures.
