Why is the Test Performed?
MRI provides detailed pictures of soft tissues without obstruction by overlying bone. It is often used to clarify findings from previous X-ray studies or CT scans. It can show or demonstrate wide areas of the abdomen from multiple planes. MRI can evaluate certain organ functions. It clearly shows lymph nodes and blood vessels, and is a noninvasive imaging method for evaluation of blood flow.
MRI may be used in diagnosing abnormal growths. It can distinguish tumors or other lesions from normal tissues and can provide information for the staging (determination of the size, extent, and spread) of abdominal tumors. MRI is sometimes used to avoid the dangers of angiography, repeated exposure to radiation, or for patients that cannot receive iodinated contrast dye.
