"In the hands of skilled practitioners, CCSVI can be diagnosed by producing detailed images of the major pathways draining blood from the brain and spinal cord, plus blood flow rates and reflux. Typically, the technologies used are Magnetic Resonance Venography (MRV), CT Venography, Duplex Ultrasonography, and Catheter Venography. These technologies can safely provide evidence of a wide range of vascular indicators of CCSVI, including stenoses, abnormally developed and/or twisted veins, and unusual valves or septums."
