目的通过两种不同方法对肺栓塞疾病诊断的比较,认识MSCT肺动脉重建在诊断肺栓塞的价值。方法选取我院近3年收治的肺栓塞病历19例,每例患者均行MSCT肺动脉重建及介入肺动脉造影两种方法,比较两种诊断方法阳性率,分析MSCTPA诊断肺栓塞的敏感性、特异性。结果两种肺动脉造影诊断肺栓塞疾病的阳性率没有显著的统计学差异,以介入性肺动脉造影为金标准,MSCT肺动脉重建诊断肺栓塞敏感性95.4%,特异性99.5%。结论 MSCT肺动脉重建诊断肺栓塞具有极高的敏感性和特异性,其无创性检查结果的可靠性,在肺栓塞疾病诊断中是一种可以替代DSA造影的方法。
Objective To compare the diagnosis of pulmonary embolism by two different methods and to understand the value of pulmonary embolism in the diagnosis of pulmonary embolism by MSCT. Methods Nineteen cases of pulmonary embolism admitted in our hospital in the past three years were selected. Each patient underwent MSCT pulmonary artery reconstruction and interventional pulmonary arteriography, and the positive rates of two diagnostic methods were compared. The sensitivity and specificity of MSCTPA in the diagnosis of pulmonary embolism . Results There was no significant difference in the positive rate of pulmonary embolism between the two kinds of pulmonary arteriography. Interventional pulmonary arteriography was the gold standard. MSCT pulmonary embolism was diagnosed with sensitivity of 95.4% and specificity of 99.5%. Conclusion The diagnosis of pulmonary embolism by MSCT is of high sensitivity and specificity. The reliability of noninvasive examination results is an alternative to DSA in the diagnosis of pulmonary embolism.
