This study evaluated the use of radionuclide venography (RNV) as a screening test for patients with signs and symptoms of deep venous thrombosis (DVT). Seventy patients underwent RNV; 27 of the 70 patients also had contrast venography. The incidence of DVT was 19% (13 of 70). RNV had an observed sensitivity of 93% and an observed specificity of 100%. Follow-up at one month revealed no evidence of thromboembolic disease in patients with a negative scan. RNV is an accurate, practical screening test for DVT.
本研究评估了放射性核素静脉造影（RNV）作为深静脉血栓形成（DVT）体征和症状患者筛查试验的应用。70例患者接受了RNV检查；70例患者中的27例还进行了造影剂静脉造影。DVT的发生率为19%（70例中的13例）。RNV观察到的敏感性为93%，观察到的特异性为100%。1个月的随访显示，扫描结果为阴性的患者没有血栓栓塞性疾病的证据。RNV是一种准确、实用的DVT筛查试验。
