Computed tomographic findings in 18 patients with pulmonary thromboembolism are retrospectively reviewed. In the majority of patients, thromboembolism was not suspected clinically. The CT findings can be divided into two groups: vascular and parenchymal changes. The most frequent vascular findings is an intraluminal filling defect or defects due to thrombus. The most frequent parenchymal finding is a triangular (wedge-shaped) pleural-based soft tissue attenuation lesion. Although CT is not a primary diagnostic tool in the evaluation of pulmonary thromboembolism, CT may be helpful in diagnosis of pulmonary embolism, when evaluating an undiagnosed parenchymal density.
回顾性分析了18例肺血栓栓塞症患者的计算机断层扫描结果。大多数患者临床上未怀疑有血栓栓塞。CT表现可分为两组：血管改变和实质改变。最常见的血管表现是管腔内由于血栓形成的充盈缺损。最常见的实质表现是三角形（楔形）的胸膜下软组织密度病变。虽然CT不是评估肺血栓栓塞症的主要诊断工具，但在评估未确诊的实质密度时，CT可能有助于诊断肺栓塞。
