OBJECTIVES: To determine the diagnostic value of CT venography after CT angiography of the pulmonary arteries using multislice helical CT in the diagnosis of @entity1151 . METHODS: Between September 1999 and April 2001 252 @entity1 with clinically suspected @entity1151 were examined. CT angiography of the pulmonary arteries was followed by CT venography of the inferior vena cava, the iliac veins and the proximal femoral veins; after April 2000 the popliteal veins and the proximal lower leg veins were additionally investigated. The examinations were performed with a double detector and a multidetector scanner (Elscint Twin and GE Lightspeed). RESULTS: @entity1151 was found in 79/252 @entity1 (40 central and 39 @entity1347 ). In 38/40 @entity1 with central PE and in 22/39 @entity1 with @entity1347 in CT venography a @entity1150 was detected, in 1/79 @entity1 a doubled inferior vena cava could be found. In 5 @entity1 with @entity715 of the inferior vena cava a transjugular cava filter placement was performed. In 13/173 @entity1 without @entity1151 CT venography showed @entity1150 . CONCLUSION: CT venography of the lower extremities is a practical and efficient additional examination to CT angiography in clinical suspected @entity1151 . It can detect the causing @entity49 with a high sensitivity.
