A physician can use magnetic resonance (MR) venography to observe the veins present inside the cranium. The venogram utilizes an MRI unit to create images of blood vessels in patients suffering from stroke, aneurysms, or heart disease.
Locations Offering This Procedure:
Preparing For The Procedure:
The patient should wear loose clothing for the procedure. Remove all metal objects, such as jewelry and eyeglasses prior to the procedure. Refrain from eating or drinking in the hours before the procedure. Additional preparations will be made known to you by your physician.
During The Procedure:
The patient is positioned on an exam table. A coil or cuff will be put on the area in question. The coil itself does not cause any discomfort. Once positioned, the table will move into the MRI unit. The process takes about 45 minutes.
What Will I Experience?
MRV utilizes a traditional MRI unit to conduct imaging of the blood vessels. Some patients may feel claustrophobic inside a “closed” MRI unit, and may be administered a mild sedative to alleviate anxiety.
MRV can effectively detect and diagnose abnormalities of the vascular system in a less invasive way than a catheter angiogram. This can often eliminate the need for surgery through early detection of certain conditions. It does not expose the patient to radiation, making it safe and non-invasive.
