A.

All metallic objects on the body are removed prior to obtaining a magnetic resonance imaging scan. Occasionally, patients will be given a sedative medication to decrease anxiety and relax the patient during the MRI scan. MRI scanning requires that the patient lie still for best accuracy. Patients lie within a closed environment inside the magnetic machine. Relaxation is important during the procedure and patients are asked to breathe normally.

Interaction with the MRI technologist is maintained throughout the test. There are loud, repetitive clicking noises, which occur during the test as the scanning proceeds. Occasionally, patients require injections of liquid intravenously to enhance the images obtained. The MRI scanning time depends on the exact area of the body studied, but ranges from a half-hour to an hour-and-a-half.
