title: [Spiral volumetric CT venography of the lower extremities: preliminary report].
abstract: Twelve cases, including varicose veins (7), deep venous thrombosis (3), A-V malformation (1) and skin ulcer (1), were examined by three-dimensional CT venography (3D CTV), and comparison was made with conventional ascending venography. In the "double phase method," the first phase scan (40 seconds) of the femoral region was performed in order to rule out deep venous thrombosis, and the second phase scan (30 seconds) of the lower leg was performed to visualize varicose veins. Veins of the thigh and popliteal space were relatively well visualized. It is thought that 3D-CTV is particularly useful for spatially evaluating deep venous thrombosis and varicose veins.
