A total of 22 MR venograms were performed in 7 volunteers and 15 patients suspected of deep vein thrombosis of the lower limb and pelvis. MR findings were compared to conventional venography in all patients. MR venography is a reliable method for the exclusion of thrombosis proximal to the popliteal vein. In the calf veins, diagnosis of thrombosis is not yet reliable. For MR venography 2D-time-of-flight-inflow-technique and secondary 3D-MIP reconstructions were used and compared to each other. With both methods there were no false negative results in comparison to conventional venography. 2D single slice MR venography showed two false positive results in iliac and one in popliteal vein. MIP 3D reconstructions led to seven false positive results (three iliac, two femoral, two popliteal). The exclusive interpretation of MIP-3D reconstruction is not reliable for decision-making in deep venous thrombosis.
对7名志愿者和15名疑似下肢及骨盆深静脉血栓形成的患者共进行了22次磁共振静脉造影。对所有患者的磁共振成像结果与传统静脉造影进行了比较。磁共振静脉造影是排除腘静脉近端血栓形成的可靠方法。在小腿静脉中，血栓形成的诊断尚不可靠。磁共振静脉造影采用二维时间飞跃流入技术和二次三维最大密度投影重建，并相互比较。与传统静脉造影相比，两种方法均未出现假阴性结果。二维单层磁共振静脉造影在髂静脉显示2例假阳性结果，在腘静脉显示1例假阳性结果。三维最大密度投影重建导致7例假阳性结果（3例髂静脉、2例股静脉、2例腘静脉）。三维最大密度投影重建的单独解读在深静脉血栓形成的决策中并不可靠。
