目的探讨螺旋CT诊断肺动脉栓塞的临床应用价值。方法对经临床诊断及病理核实的肺动脉栓塞患者50例病例资料进行回顾性分析。结果 50例肺栓塞患者中,中央肺动脉栓塞患者11例,肺段或肺叶动脉栓塞患者30例,肺段下方动脉栓塞患者9例。所有患者中,右肺动脉中探查出最大栓子,直径为28.8 mm,肺段下方动脉栓塞中探查出存在最小栓子,直径为1.1 mm。结论螺旋CT诊断扫描速度快,具有较高的空间分辨率,征象显示明确,可替代肺动脉造影成为肺栓塞诊断的首选方法。
Objective To investigate the clinical value of spiral CT in the diagnosis of pulmonary embolism. Methods Fifty cases of pulmonary embolism diagnosed by clinical diagnosis and pathology were retrospectively analyzed. Results Of the 50 patients with pulmonary embolism, there were 11 patients with central pulmonary embolism, 30 patients with pulmonary or pulmonary embolism, and 9 patients with arterial embolism under the pulmonary segment. In all patients, the largest emboli were detected in the right pulmonary artery with a diameter of 28.8 mm. The smallest emboli were found in the arterial embolization below the pulmonary segment with a diameter of 1.1 mm. Conclusion Spiral CT has the advantages of fast scanning speed, high spatial resolution, clear signs and can replace pulmonary angiography as the preferred method of pulmonary embolism diagnosis.
