An MRI (or magnetic resonance imaging) scan is a radiology technique that uses magnetism, radio waves, and a computer to produce images of body structures. The MRI scanner is a tube surrounded by a giant circular magnet. The patient is placed on a moveable bed that is inserted into the ma...

The MRI scan is performed inside a large magnet, and the person lies on the table in the center. During the procedure, the machine scans the body by turning small magnets on and off. Radio waves are sent into the body. The machine then receives returning radio waves and uses a computer...
During an MRI, a person will be asked to lie on a movable table that will slide into a doughnut-shaped opening of the machine to scan a specific portion of your body. The machine itself will generate a strong magnetic field around the person and radio waves will be directed at the body...
The CT scanner looks like a big donut and it has a narrow table present in its center. During MRI scan, the patient is placed inside the tunnel of the scanner and can feel claustrophobic; whereas in CT scan, the patient rarely feels claustrophobic due to the openness of the doughnut shape...
The MRI scan with contrast works by highlighting specific parts of your soft tissue, helping the radiologist come up with a diagnosis of your condition. In particular, tumor growths or other severe developments are simpler for the radiologist to identify when using contrast with the MRI scan. Si...
