Magnetic resonance venography (MRV) is an imaging test that uses magnetic resonance technology and intravenous (IV) contrast dye to visualize veins in the body.
What is magnetic resonance venography (MRV)?
Magnetic resonance venography is a diagnostic procedure that uses a combination of a large magnet, radio frequencies and a computer to produce detailed images of organs and structures within the body. An MRV uses magnetic resonance technology and intravenous (IV) contrast dye to visualize the veins. This test mainly evaluates central vein compression syndrome and intra-abdominal venous pathology which is not well visualized on duplex
