The goal of imaging studies is to identify and map all areas of acute or chronic obstruction and all areas of reflux within the deep and superficial venous systems. Successful imaging of the deep venous system requires a thorough knowledge of venous anatomy and physiology and a meticulous attention to detail. The most useful modalities available for venous imaging are contrast venography, magnetic resonance imaging (MRI), and color-flow duplex ultrasonography.
