摘　　要：目的探讨多层螺旋CT与超声心动图在肺动脉高压诊断中的应用价值。方法选取2014年1月~2019年1月就诊于本院疑似肺动脉高压患者共78例作为研究对象,给予所有患者多层螺旋CT与超声心动图检查诊断,以右心导管检查结果为"金标准",分析多层螺旋CT与超声心动图检查诊断肺动脉高压符合率、敏感度和特异度,观察肺动脉高压患者多层螺旋CT与超声心动图成像特点。结果右心导管检查结果显示,72例患者确诊为肺动脉高压,诊断准确率、特异度及敏感度均为100%;CT检查结果显示,78例患者中74例确诊为肺动脉高压,误诊2例,诊断准确率97.44%,其中真阳性72例、真阴性6例、假阳性2例、假阴性1例,诊断敏感度97.30%、特异度75.00%,与右心导管检查结果比较差异无统计学意义(P>0.05);超声心动图检查结果显示,78例患者中73例确诊为肺动脉高压,误诊1例,诊断准确率98.72%,其中真阳性72例,真阴性6例,假阳性1例,假阴性1例,诊断敏感度98.63%、特异度85.71%,与右心导管检查结果比较差异无统计学意义(P>0.05);三种诊断方法对肺动脉高压病理特征分类准确率比较差异无统计学意义(P>0.05)。结论多层螺旋CT与超声心动图检查诊断肺动脉高压均可获得较高的准确率、敏感度及特异度,具有操作简便、无创、经济实惠等优点,临床中可根据患者实际情况合理选择。Objective To explore the value of multi-slice spiral CT and echocardiography in the diagnosis of pulmonary hypertension. Methods 78 patients with suspected pulmonary hypertension from January 2014 to January 2019 were selected as the study subjects. All patients were diagnosed by multi-slice spiral CT and echocardiography. The results of right cardiac catheterization were regarded as "gold standard". The coincidence rate, sensitivity and specificity of multi-slice spiral CT and echocardiography in the diagnosis of pulmonary hypertension were analyzed, and the characteristics of multi-slice spiral CT and echocardiography in patients with pulmonary hypertension were observed.Results The results of right cardiac catheterization showed that 72 patients were diagnosed as pulmonary hypertension, the diagnostic accuracy, specificity and sensitivity were 100%. CT examination showed that 74 of 78 patients were diagnosed as pulmonary hypertension, 2 were misdiagnosed, and the diagnostic accuracy was 97.44%. Among them, 72 cases were true positive, 6 cases were true negative, 2 cases were false positive and 1 case was false negative. The diagnostic sensitivity and specificity were 97.30% and 75.00% respectively. The results of echocardiography showed that 73 of 78 patients were diagnosed as pulmonary hypertension, 1 was misdiagnosed, and the diagnostic accuracy was 98.72%. There were 72 true-positive cases, 6 true-negative cases, 1 false-positive case and 1 false-negative case. The diagnostic sensitivity and specificity were 98.63% and 85.71%, respectively, which were different from those of right heart catheterization. There was no statistical significance(P>0.05);there was no significant difference in the accuracy of pathological classification of pulmonary hypertension among the three diagnostic methods(P>0.05). Conclusion Both multi-slice spiral CT and echocardiography can obtain high accuracy, sensitivity and specificity in the diagnosis of pulmonary hypertension. They have the advantages of simple operation, non-invas
