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)?
Quick answer
An MRV is a scan that shows the veins in your body. It combines a large magnet, radio frequencies and a computer with contrast dye given through an IV line, and it produces detailed pictures of your veins and the structures around them. The main use is checking for central vein compression and vein problems inside the abdomen. Those are the ones a duplex ultrasound often cannot show clearly.
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
