What is MRI?
Magnetic resonance imaging uses radio wave energy in a magnetic field. The signal generated by the radio waves produce very detailed images of the human body. The advantage of MRI is its precise image detail that enables physicians to locate extremely small defects or disease processes. MRI is considered a very common procedure for virtually every area of medicine.

How do patients prepare for the exam?
Unless a patient receives a sedative or anesthesia, there is no preparation for the exam. Patients should wear comfortable clothing and take precautions for entering a magnetic field. Removing all metal items prior to entering the procedure room (like jewelry, keys, and wallets) is standard. Patients with pacemakers, implants, cardiac stents or other metal devices within the body may still qualify for MRI scanning. It is important for patients to discuss implanted devices with their physician and the MRI staff.

How is the exam performed?
An MRI scan is a very easy exam. Patients complete a questionnaire regarding medical history as well as MRI safety issues. Most exams last 30 to 60 minutes depending on the type of exam ordered by the physician. Normal dress is acceptable provided ALL metal objects are removed. The staff provides a hospital gown if clothing is a concern.
Once all safety information is obtained, patients lie on the imaging table. If a physician has requested a contrast agent, the staff will insert an IV. Ear plugs are also provided.

Loud knocking or clicking noises are normal for MRI units. Once scanning begins, patients should be as still as possible. Side affects or allergic reactions to MRI contrast materials are rare. CMC staff is fully prepared to assist in these unusual circumstances.

When are results available?
Physicians provide exam results. The radiologist interprets the MRI scans the day they are performed. Some cases may require comparison to other exams, resulting in a slight delay. CMC provides results directly to physicians as soon as the radiologist verifies the report accuracy.
