An MRV is the process of radiation that uses magnetic rays to study the blood vessels.
What is MRI Venography?
Magnetic Resonance Venography is the radiation that is done to visualize the veins in the body.
This process uses a combination of a large magnet, computer and radio frequencies to generate the image of organs. The detailed pictures of the structures within the body help the radiologist to explain causes of various vein problems. It is helpful in finding out the cause of leg pains and other vein problems. Contrast is also used in this process to produce better images.
This radiology is performed to get a better look of the veins throughout the body.
How is MRI Venography performed?
This radiology includes the following procedures:
- A table will be provided for you to lie down.
- The table will slide into the huge MRI machine.
- You will be asked to lie very still, without any movement.
- You may also be asked to stop breathing for a few seconds.
If you are claustrophobic, a mild sedative may be given before the radiology.
Side effects/risks of MRI Venography
Since there is a limited amount of radiation being used in this radiology, there is no much risk involved in this method. If, however, you have been given contrast, you may experience some irritation or allergies.

Before going in for the radiology, you will need to:
- Change into hospital gowns.
- Remove any piece of jewellery made of metal from your body including hairpins.
