What is an MRV?
Magnetic resonance imaging, or MRI, is a method of producing detailed pictures of organs and body tissues by exposing a patient to radio waves in a strong magnetic field. The field is measured and analyzed by a computer, which forms two- or three-dimensional images that may be viewed on a monitor. Because it uses radio waves and a magnetic field rather than x-rays, there is no exposure to radiation.
MRV stands for magnetic resonance venography. It is an MRI studies of the blood vessels. MRVs are used to assess abnormalities in the blood vessels of patients with a history of stroke, aneurysm, heart disease, and atherosclerotic vascular disease.
Why might my doctor recommend an MRV?
If you experience frequent headaches, an MRV of the head may be recommended to detect or rule out blood clots in the brain. An MRV of the chest is used to detect blood clots or blockages in the main arteries leading to the heart, and an MRV of the abdomen checks for blood clots or blockages in the liver.
How should I prepare for my MRV?
On the day of the procedure, wear comfortable clothing and try to relax. Before the procedure begins, you will be asked if you have any metal medical equipment in your body such as a pacemaker, intrauterine device (IUD), implanted port, or infusion catheter. Due to the strong magnetic fields created by MRV, these devices may interrupt the procedure. Also, make sure to notify the technologist if you might be pregnant. Before the procedure begins you also will be asked to remove any metal jewelry or metal external objects as they may interfere with the procedure.
How is an MRV performed?
You will be asked to lie on your back on a cushioned table. A device called a coil will be placed on the area to be scanned. Coils are antennas used in every scan to help image the area of interest. Different coils are designed for different parts of the body and will conform to your shape as you are being imaged. You will not experience any discomfort from the coil.
After you are positioned, the table will move under the magnet. The radiologic technologist will leave the room once the procedure begins to control the equipment and perform your scan. You will be able to communicate with the technologist through an intercom during the procedure. The machine will make a slight rapping sound as the images are being taken. In between scans the machine is quiet. The process takes between 30 and 45 minutes and is painless.
What type of equipment is used for an MRV?
An MRV can be performed in either a closed or an open MRI scanner. A closed scanner requires you to lie in a cylinder-like compartment. An open MRI is ideal for claustrophobic, pediatric, elderly, and large patients. This procedure uses a scanner that is less confining. Both types of scanners can provide your physician with accurate and detailed images.
Will I experience any side effects from the MRV?
In some cases, your physician or the radiologist may request a contrast agent (dye) be used to improve the quality of the images. The agent is designed to make organs and blood vessels more visible, and will likely cause no side effects. You may experience a metallic taste in your mouth and in rare cases you may experience more serious side effects. The technologist can answer any questions about possible side effects.
How will I get the test results of my MRV?
The results of your MRV are read by the board-certified radiologists of Professional Radiology, Inc. A detailed report will be sent to your referring physician within 24 hours.
