Answer

Magnetic resonance venography (MRV) is the most sensitive and most specific test for deep and superficial venous disease in the lower legs and in the pelvis, where other modalities cannot reach. MRV is particularly useful because unsuspected nonvascular causes for leg pain and edema may often be observed on the MRV scan when the clinical presentation erroneously suggests venous insufficiency or venous obstruction.
