Pulmonary embolism is a frequent and potentially life-threatening event with uncharacteristic clinical manifestations. Diagnosis is commonly established by ventilation/perfusion scintigraphy and pulmonary angiography. Both methods, however, carry substantial drawbacks. Therefore, clinicians claim that there is a need for an accurate and non-invasive diagnostic modality. Spiral CT of the pulmonary arteries is a recent modality, that allows reliable visualization of emboli in pulmonary arteries up to fourth-order branches. This paper reviews the technical aspects, typical findings and diagnostic pitfalls of this recent technique. The potential role of spiral CT in the screening of patients with suspected pulmonary embolism is discussed and selected cases are presented.
肺栓塞是一种常见且可能危及生命的疾病，临床表现不典型。诊断通常通过通气/灌注闪烁扫描和肺血管造影来确立。然而，这两种方法都有很大的缺点。因此，临床医生声称需要一种准确且无创的诊断方法。肺动脉螺旋CT是一种新的检查方法，它能够可靠地显示直至四级分支肺动脉内的栓子。本文回顾了这项新技术的技术要点、典型表现及诊断陷阱。讨论了螺旋CT在疑似肺栓塞患者筛查中的潜在作用，并列举了一些病例。
