【摘要】：目的探究对肺栓塞患者应用多层螺旋CT诊断的临床价值。方法将某院接收的40例被疑诊为肺栓塞的患者作为研究对象,均给予多层螺旋CT检查;并以溶栓治疗效果以及多种检查结果作为金标准,对CT检查准确性进行评价。结果肺叶动脉显示数198支、栓塞数为69支,栓塞率为34.84%,肺段动脉显示数为639支,栓塞数为258支,栓塞率为40.38%,主肺动脉显示数为76支,栓塞数为18支,栓塞率为23.68%,亚段动脉显示数为1934支,栓塞数为92支,栓塞率为4.76%,其他分支动脉显示数为4587支,栓塞数为40支,栓塞率为0.87%;40例被疑诊为肺栓塞患者由多种检查结果最后被明确诊断为肺栓塞的患者40例,而多层螺旋CT检查结果显示检查出肺栓塞37例,3例漏诊。CT敏感度为92.5%。结论在肺栓塞患者中应用多层螺旋CT检查,扫描其肺动脉与其分支,显示结果清晰,且肺动脉栓塞诊断特异性与敏感性较高,与动脉造影技术相比对患者机体无创伤性,临床上可当做肺栓塞影像学检查的首选。
[Abstract]:Objective to explore the clinical value of multi-slice spiral CT in the diagnosis of pulmonary embolism. Methods 40 patients suspected of pulmonary embolism in a hospital were examined by multi-slice spiral CT, and the accuracy of CT was evaluated by using the effect of thrombolysis and the results of various examinations as gold standards. Results there were 198 branches of pulmonary artery, 69 branches of pulmonary artery, 34.84% of them, 639 branches of pulmonary artery, 258 branches of pulmonary artery, 40.38% of them, 76 branches of main pulmonary artery, 18 branches of embolism, 23.68% of them, 1934 branches of subsegmental artery, 92 branches of embolism, 4.76% of other branches of pulmonary artery, 4587 branches and 40 branches of pulmonary artery, the embolic rate was 23.68%, the number of subsegmental arteries was 13.68%, the embolic rate was 34.84%, the number of pulmonary arteries was 639, the number of embolic arteries was 258, the embolic rate was 40.38%, the number of main pulmonary arteries was 76, the number of embolic arteries was 23.68%. The embolic rate was 0.87%. 40 patients with suspected pulmonary embolism were finally diagnosed as pulmonary embolism by a variety of examination results. The results of multi-slice spiral CT showed that 37 cases of pulmonary embolism were detected and 3 cases were missed. The sensitivity of CT was 92.5%. Conclusion Multi-slice spiral CT is used to scan the pulmonary artery and its branches in patients with pulmonary embolism. The results are clear, and the diagnostic specificity and sensitivity of pulmonary embolism are high. Compared with arteriography, it is noninvasive and can be used as the first choice for imaging examination of pulmonary embolism.
