Definition: The type of magnetic resonance imaging (MRI) used to visualize veins, the blood vessels that bring blood from the body's internal organs back into the systemic circulation.

The MRV uses the same machine as an MRI, but a special computer software allows it to only extract generated-by-blood images, as it flows through the veins. These images give doctors a rough idea of whether blood flow through a vein of interest is affected by blood clots or other disease processes.
