MRV Meaning Medical
MRV stands for magnetic resonance venography, a non-invasive imaging technique that uses MRI technology to create detailed images of veins and blood flow. It is usually done on the brain and neck. MRVs are often used to diagnose conditions such as blood clots, venous malformations, and venous stenosis, particularly in the brain and neck.
Here are some things to know about MRVs:
How it works
MRVs use radio waves and a strong magnetic field to create images. A contrast dye injection is often used to enhance the visibility of veins.
What MRV is used for
-
- Detecting blood clots
- Diagnosing venous malformations
- Identifying venous stenosis
- Evaluating blood flow in the brain
- Detecting deep vein thrombosis
- Assessing conditions that cause neurological symptoms
Safety
MRVs don’t use radiation, but patients should be screened for any metal devices in their body. Patients will need to remove all jewelry.
Comfort
MRVs are generally comfortable, but they can be challenging for people who are claustrophobic. Claustrophobic means a person with an extreme or irrational fear of confined spaces. Patients who are nervous or uncomfortable may be given a relaxant or pain medication.
Cost of MRV
MRVs can cost between $500–600.
Risks
There are some risks associated with MRVs, including the possibility of false positive results, a contrast reaction, and spending extra time in the scanner
