Blood pool radionuclide venography and contrast venography were carried out in 50 patients in whom deep vein thrombosis was suspected. The two procedures were compared on the basis of 198 individual vessel segments. The overall concordance between radionuclide and contrast venography was 92%. Using contrast venography as the standard, the sensitivity of radionuclide venography was 90% and specificity 96%. The predictive accuracy of a positive test was 77% and of a negative test was 97%. The performance of radionuclide venography improved if the calf veins were excluded from analysis. The main limiting factor affecting the performance of radionuclide venography was the moderately poor resolution of the technique. Technical manipulations to improve resolution were time consuming and added little to the accuracy of the test. Radionuclide will not replace contrast venography but may well be used to complement contrast venography when it is technically unsatisfactory or unequivocal, in patients with a history of intolerance to contrast media, and in bedbound patients.
对50例疑似深静脉血栓形成的患者进行了血池放射性核素静脉造影和造影剂静脉造影。根据198个独立血管段对这两种检查方法进行了比较。放射性核素静脉造影与造影剂静脉造影的总体一致性为92%。以造影剂静脉造影为标准，放射性核素静脉造影的敏感性为90%，特异性为96%。阳性检查的预测准确性为77%，阴性检查的预测准确性为97%。如果在分析中排除小腿静脉，放射性核素静脉造影的性能会有所改善。影响放射性核素静脉造影性能的主要限制因素是该技术的分辨率中等较差。提高分辨率的技术操作耗时且对检查准确性的提高作用不大。放射性核素不会取代造影剂静脉造影，但在造影剂静脉造影技术上不满意或不明确时、有造影剂不耐受史的患者以及卧床患者中，很可能可用于补充造影剂静脉造影。
