What Is An MRI?

MRI machineMRI/MRA (Magnetic Resonance Imagings/Angiography) is a non-invasive procedure (no cut or surgical opening performed on the patient) that uses computers to obtain detailed images of your body. MRI does not use x-rays. It takes advantage of the water molecules in your body combined with a powerful magnetic unit and radio frequencies to obtain images. The body part to be examined is placed into a device called as MRI coil, which is used to transmit and receive signals from your body. A computer interprets the signals into a series of detailed images which is then transferred to a monitor or a sheet of film similar to x-ray film.

A specialist known as a Radiologist reads your images and the interpretation of the images (readings) are sent to your doctor who ordered the examination.
