Spiral CT, venous ultrasound, ventilation-perfusion scanning, and D-dimer tests are routinely used in the diagnosis of venous thromboembolic disease. Advances in multidetector spiral CT and the combination of CT pulmonary angiography and venography as a one-step evaluation of venous thromboembolic disease have markedly improved detection of subsegmental emboli and deep pelvic venous thrombi and decreased the role of conventional pulmonary angiography. As CT has improved, many have questioned what "gold standard" CT should be compared with. Recent clinical outcome studies suggest that CT results are as good as pulmonary angiography and conventional imaging algorithms. Because the sensitivity of CT pulmonary angiography now exceeds 85%, it also appears that it is also more cost effective than other diagnostic approaches.
螺旋CT、静脉超声、通气灌注扫描和D-二聚体检测常用于静脉血栓栓塞性疾病的诊断。多排螺旋CT的进展以及CT肺动脉造影和静脉造影相结合作为静脉血栓栓塞性疾病的一站式评估，显著提高了亚段栓子和盆腔深静脉血栓的检测率，并降低了传统肺血管造影的作用。随着CT技术的改进，许多人质疑CT应与何种“金标准”进行比较。最近的临床结果研究表明，CT结果与肺血管造影和传统成像算法一样好。由于目前CT肺动脉造影的敏感性超过85%，它似乎也比其他诊断方法更具成本效益。
