摘要
目的探讨多层螺旋CT在急性肺栓塞患者临床诊断中的应用价值。方法选取50例疑似急性肺栓塞患者进行研究,并分别进行多层螺旋CT以及X线检查,评估两种检查方式对疾病的检出率以及准确率。分析两种检查方法的诊断结果;比较两种检查方法的诊断效能,对不同类型疾病的检出率,对不同动脉分支栓塞的检出率。结果以动脉造影为“金标准”,阳性43例(包括急性广泛性肺栓塞27例、急性广泛性亚肺栓塞16例),阴性7例(均为慢性肺栓塞)。多层螺旋CT检查显示阳性41例,阴性9例;X线检查显示阳性38例,阴性12例。多层螺旋CT的灵敏度93.02%、特异度85.71%、诊断准确度92.00%、阴性预测值66.67%高于X线检查的76.74%、28.57%、70.00%、16.67%(P<0.05);两种检查方法的阳性预测值对比,差异无统计学意义(P>0.05)。多层螺旋CT对急性广泛性肺栓塞、急性广泛性亚肺栓塞、慢性肺栓塞的检出率分别为96.30%、100.00%、100.00%,比X线的70.37%、68.75%、42.86%更高(P<0.05)。多层螺旋CT对不同动脉分支栓塞的检出率100.00%高于X线的85.96%(P<0.05)。结论多层螺旋CT可对急性肺栓塞进行精准判断,相较于X线诊断准确度更高,诊断效能整体预测情况也十分理想,为临床制定详细诊疗方案提供了有力参考依据,值得临床推广。
Objective To explore the practical value of multi-slice spiral CT in diagnosis of acute pulmonary embolism.Methods 50 patients with suspected acute pulmonary embolism were selected for study,and multi-slice spiral CT and X-ray detection were performed simultaneously to evaluate the detection rate and accuracy of the two methods.The diagnostic results of the two methods were analyzed.The diagnostic efficacy,detection rate of different types of diseases and detection rate of embolization in different arterial branches were compared between the two methods.Results Using arteriography as the"gold standard",43 cases were positive(including 27 cases of acute generalized pulmonary embolism and 16 cases of acute generalized sub-pulmonary embolism)and 7 cases were negative(all of them were chronic pulmonary embolism).Multislice spiral CT showed 41 positive cases and 9 negative cases;X-ray showed 38 positive cases and 12 negative cases.The sensitivity of multi-slice spiral CT was 93.02%,the specificity was 85.71%,the diagnostic accuracy was 92.00%and the negative predictive value was 66.67%,which were higher than 76.74%,28.57%,70.00%and 16.67%of X-ray(P<0.05).There was no significant difference in positive predictive value between the two methods(P>0.05).The detection rates of multi-slice spiral CT for acute generalized pulmonary embolism,acute generalized subpulmonary embolism and chronic pulmonary embolism were 96.30%,100.00%and 100.00%,which were higher than 70.37%,68.75%and 42.86%of X-ray(P<0.05).The detection rate of multi-slice spiral CT for embolism in different arterial branches was 100.00%,which was higher than 85.96%of X-ray(P<0.05).Conclusion Multislice spiral CT can accurately judge acute pulmonary embolism,which is more accurate than X-ray,and the overall prediction of diagnostic efficiency is also very ideal,which provides a strong reference for the clinical formulation of detailed diagnosis and treatment plan,and is worthy of clinical promotion.
