摘要
目的:探讨16层螺旋CTA在肺动脉栓塞(PE)诊断中的临床价值。材料与方法:收集经临床证实为肺动脉栓塞的25例患者CTA资料,对其直接征象及间接征象进行回顾性分析。结果:25例CT图像均能显示栓子数量、部位、范围、密度及局部狭窄程度,直接征象为充盈缺损,间接征象包括肺纹理稀疏、肺梗死及肺动脉高压、胸腔积液等。结论:16层螺旋CTA对PE诊断具有明显优势,是面前诊断PE的首选方法。
Purpose： To explore the clinical value of 16-slice spiral CT in diagnosis of pulmonary embolism （PE）. Materials and Methods： CTA data of 25 patients with clinically proven pulmonary embolism were collected, the direct and indirect signs were retrospectively analyzed. Results： 25 cases of CTA images can display the number, position, range, thrombus density and local stenosis. Direct sign is filling defect. Indirect signs include pulmonary texture sparse, pulmonary infarction, pulmonary hypertension, pleural effusion, and so on. Conclusion： 16-slice spiral CTA has obvious advantages in the diagnosis of PE, and it is the first choice for the diagnosis of PE.
