Simultaneous MR arteriography and venography with blood pool contrast agent detects deep venous thrombosis in suspected arterial disease. This study was structured so that each protocol could be individually assessed to determine usefulness. Continuous observation without transducer movement or identifying the compressibility of the lumen can be helpful to differentiate this condition from true thrombosis. The technologist applies a small amount of gel to the area under examination and places the transducer there.
