Magnetic Resonance Imaging (MRI) of the Abdomen

Abdominal MRI, MRI of the Abdomen

Results

Magnetic resonance imaging (MRI) is a test done with a large machine that uses a magnetic field and pulses of radio wave energy to make pictures of organs and structures inside the belly.

The radiologist may discuss initial results of the MRI with you right after the test. Complete results are usually available for your health professional in 1 to 2 days.

An MRI scan can sometimes find a problem in a tissue or an organ that is not seen by X-ray, ultrasound, or CT scan, even when the size and shape of the tissue or organ looks normal.

	No signs of inflammation or infection are present.
Abnormal:	An organ is too large, too small, or in the wrong place. The MRI also may show areas of scarring or injury.
