The purpose of this study was to determine the value of a blood-pool contrast media ( @entity16710 , Nycomed Imaging (now Amersham Health) Oslo, Norway) for evaluation of @entity1150 and lower extremities. Twelve @entity1 were prospectively evaluated with conventional X-ray venography (XRV) and MR venography (MRV) after injection of @entity16710 (2 ml/kg body weight). The source images and 3 @entity8906 intensity projection (MIP) were viewed on an independent workstation. Diagnosis was made in consensus from two radiologists. Diagnostic image quality was achieved in 87 veins with XRV and MRV. As determined by XRV, @entity715 was present in 30 out of 87 veins (34.5%). There was agreement concerning absence or presence of thrombi in 83 out of 87 veins (95.4%; kappa = 0.9 +/- 0.05). Compared to XRV, overall sensitivity and specificity of blood-pool MRV were 93.3% and 96.5%, respectively. Two venous thromboses of the popliteal and posterior tibial vein were diagnosed in MRV, but not in XRV. Conversely, two venous thromboses below the knee had been missed by MRV. @entity16710 allows prolonged and improved visualization of the peripheral vasculature and may overcome some limitations of @entity2287 contrast media. A more complete examination of the proximal venous tree may be possible than with conventional XRV. Arterial and venous enhancement and motion artifacts can limit image interpretation.
