Magnetic Resonance Cholangiopancreatography (MRCP)
MRCP uses magnetic resonance imaging, a noninvasive test that produces cross-section images of parts of the body. After being lightly sedated, the patient lies in a cylinder-like tube for the test. The technician injects dye into the patient's veins that helps show the pancreas, gallbladder, and pancreatic and bile ducts.
