肺栓塞患者行多层螺旋CT诊断的临床应用价值

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。

Clinical Application Value of Multi-slice CT Diagnosis on Patients with Pulmonary Embolism

Objective To explore application clinical diagnosis value of multi-slice CT on patients with pulmonary embolism.Methods Forty patients suspected and diagnosis to suffer from pulmonary embolism admitted by the Hospital were selected as research subjects, all of them were subject to multi-slice CT examination, the efficacy of thrombolysis and multiple test results were treated as gold standard, and the accuracy of CT examination was evaluated.Results There were 205 displays of lung artery and 69 units of embolism with the embolism rate at 34.84%, 639 units of pulmonary artery manifestations, 258 units of embolism with the embolism rate at 40.38%, the number of aorta manifestations hit 76, the number of embolism came up to 18 units with the embolism rate at 23.68%, the number of artery showed manifestations hit 1934, and the units of embolism amounted 92 with the manifestations rate at 4.76%, the units of other branch arteries hit 4587, and the number of embolism hit 40 with the embolism rate at 0.87%. Forty patients were suspected to suffer from pulmonary embolism, and finally they were clearly diagnosed to suffer from pulmonary embolism, and multi-slice CT examination results showed that 37 patients with pulmonary embolism with 3 patients being missed diagnosis were examined. The sensitivity of CT was 92.5%.Conclusion Multi-slice CT examination can have a clear show, applied on the pulmonary artery and its branches with pulmonary embolism , and the diagnosis specificity and sensitivity on pulmonary embolism are high, it casts no traumatism on patients when compared to angiography technique, and it may be the top priority for imaging examination for pulmonary embolism.
