Magnetic resonance venography, or MRV, is a variation of magnetic resonance angiography. Magnetic resonance angiography, or MRA, encompasses several methods based on Magnetic Resonance Imaging, or MRI, to create images of blood vessels. Magnetic resonance angiography is used to observe arteries for abnormal narrowing, or stenosis, occlusion or aneurysms, which are vessel wall dilatations that are at risk of rupturing. MRA is often used to evaluate the arteries of the thoracic and abdominal aorta, the neck and brain, the legs and the renal arteries.
MRV is like MRA but instead of observing the arteries it is used to evaluate the veins. It is one of the methods used to diagnose CCSVI, a condition associated with multiple sclerosis. The process is not invasive and involves scanning various parts of the head and neck. There are certain protocols that are to be adhered to when carrying out an MRV scan and it usually takes 30 to 45 cases. At times it may be necessary to insert a safe dye into the patient so that the veins can be more clearly seen. There should not be any side effects to this other than perhaps a slightly metallic taste in your mouth.
At Angeles Health International an attentive medical team led by Stanford-trained Dr. Jorge Luna looks after the CCSVI patients. Both Doppler sonography and MRV can be used to diagnose the patient, or they can provide their own scans from their doctor at home if they wish, as long as they were taken within 30 days of the CCSVI treatment.
