MRI (Magnetic Resonance Imaging)

This scan is a procedure that uses a magnet, radio waves, and a computer to make a series of detailed pictures of areas inside the body. This procedure is also called nuclear magnetic resonance imaging (NMRI). A dye may be injected into the gallbladder area so the ducts (tubes) that carry bile from the liver to the gallbladder and from the gallbladder to the small intestine will show up better in the image. This procedure is called MRCP (magnetic resonance cholangiopancreatography). To create detailed pictures of blood vessels near the gallbladder, the dye is injected into a vein. This procedure is called MRA (magnetic resonance angiography).
