摘要
目的：探讨MRV诊断下肢静脉病变的应用价值。材料和方法：38例患者进行了2D TOF法下肢静脉MRV检查，其中2例进行了增强MRV检查。检查范围包括下腔静脉下段至小腿静脉。18例同时行XRA检查。结果：38例MRV共显示腘静脉以上正常深静脉395条。血栓形成5条，狭窄5条，闭塞13条。与XRA比较，MRV显示深静脉异常的灵敏度为100%，特异度为66.67%，准确度为94.44%。结论：MRV对显示下肢静脉狭窄和闭塞的部位、范围及程度的准确性较高，是一种新的无创伤的检查方法。
Abstract
Objective: To evaluate the clinical value of magnetic resonance venography in diagnosing venous disease of lower extremity. Method: Thirty-eight cases were examined with 2D TOF MRV. Contrast enhancement MRV was performed from the distal part of inferior vena cava to the shank. Result: In 38 cases, MRV showed normal deep veins in 395 segments, venous thrombosis in 5 segments, stenosis in 5 segments and occlusion in 13 segments. With the X-ray angiography(XRA) as a standard of reference, the sensitivity, specificity and the accuracy of MRV in detecting deep vein abnormalities were 100%, 66.67% and 94.44%. Conclusion: As a new repeatable noninvasive imaging examination, MRV is accurate in showing the site, range and degree of venous stenosis and thrombosis of the lower extremity.
