What is this test?

Abdominal MR venography is an MRI-based imaging test that shows the blood vessels and veins in the abdomen. Intravenous contrast may be used to make the vessels and blood flow easier to see.

Why might I need this test?

It may be ordered to investigate suspected blood clots, narrowing or obstruction of abdominal veins, unusual blood-flow patterns, or the anatomy of blood vessels before a procedure.

How is the test performed?

You lie on a table that moves inside a large MRI scanner. The scanner creates detailed images, and contrast may be injected through a vein in your arm.

How do I prepare for the test?

Follow the imaging center's instructions, including any fasting requirement. Tell the care team about metal implants, prior contrast reactions, kidney disease, or pregnancy before the scan.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

Does this test use radiation?
No. MRI uses a strong magnetic field and radio waves rather than ionizing radiation.
Why am I receiving intravenous contrast?
The contrast helps highlight blood vessels and may make blood flow and venous abnormalities easier to identify.
Will I need to lie still during the scan?
Yes. Staying still helps produce clear images, and the technologist may ask you to hold your breath briefly during certain images.
