What to Expect
Research appointments at SCAI are handled by a research coordinator for each study.
When you are contacted by a research coordinator to set up an appointment, they will ask you some screening questions 鈥� please answer completely and honestly so that appropriate precautions can be taken for your safety and the quality of the research.
MRI Study
What is MRI?
Magnetic Resonance Imaging (MRI) uses magnetic fields and radio waves to examine internal structures of the body. The procedure is non-invasive and completely harmless. No ionizing radiation (such as X-rays) or radio-active materials are used during the study. MRI is particularly useful for imaging soft tissue such as the brain in high detail. It is also capable of measuring certain physiological changes associated with brain function.
What can I expect during a scan/examination?
An MRI scan requires that you lie on your back with your head in a "tunnel," which is very similar to a CT scanner. The tunnel is open on both ends and is well lit and ventilated. The examination usually takes about 45 minutes and will be accompanied by a series of loud knocking sounds. There are no moving parts within the scanner, and the knocking sounds occur due to vibration of the machine when it alters the magnetic fields.
You may be asked to perform a task of some form during part of the scan so that the research question can be addressed.
During pauses in scanning, you will be in intercom contact with the MRI Technologist, who will also be able to see you at all times. You will also hold a buzzer to alert the MRI Technologist in case of discomfort during the scanning.
How should I prepare?
The powerful magnetic field that makes MRI work necessitates several safety measures: if you wear a pacemaker, infusion pump, certain metallic clips, heart valves or orthopedic prosthesis, these must be brought to the attention of the MRI Technologist. On the day of your MRI do not wear metallic makeup, athletic clothing with metallic antibacterial fibers, or an underwire bra. Before the examination, all metal objects including credit cards and watches must be removed.
