摘要
目的:分析多层螺旋CT在急性肺栓塞诊断中的应用价值,观察多层螺旋CT对急性肺栓塞的检出率及影像学特征。方法:将院内2020年1月~2023年6月接收的疑似急性肺栓塞20例作为本次观察对象,均采取多层螺旋CT,以血管造影检查为金标准,分析多层螺旋CT对疾病的检出率(准确率、灵敏度、特异度、阴性预测值、阳性预测值)及多层螺旋CT影像学特征。结果:以血管造影检查为金标准,检出16例患者为急性肺栓塞,为阳性,其余4例患者为阴性;多层螺旋CT检出真阴性4例,真阳性16例,假阴性0例,假阳性0例;多层螺旋CT与金标准对急性肺栓塞的检出率比较,差异无统计学意义(P>0.05)。结论:急性肺栓塞诊断中多层螺旋CT具有较高的疾病检出率,灵敏度与特异度均相对较高,检出率与金标准差异较小,能够为临床提供更高质量的影像学图片方便临床观察病情特征,为后续诊疗提供参考。
Objective:To analyze the application value of multi-slice spiral CT in the diagnosis of acute pulmonary embolism,and to observe the detection rate and imaging characteristics of multi-slice spiral CT in acute pulmonary embolism.Methods:20 suspected cases of acute pulmonary embolism received in the hospital from January 2020 to June 2023 were selected as the observation objects for this study.Multi-slice spiral CT was used,and angiography was used as the gold standard to analyze the detection rate(accuracy,sensitivity,specificity,negative predictive value,positive predictive value)and imaging characteristics of multi-slice spiral CT for diseases.Results:Using angiography as the gold standard,16 patients with acute pulmonary embolism were detected as positive,while the remaining 4 patients were negative;Multi-slice spiral CT detected 4 cases of true negative,16 cases of true positive,0 cases of false negative,and 0 cases of false positive;The detection rate of acute pulmonary embolism was compared between multi-slice spiral CT and gold standard,and the difference was not statistically significant(P>0.05).Conclusion:Multi-slice spiral CT has a relatively high disease detection rate,sensitivity and specificity in the diagnosis of acute pulmonary embolism,with a small difference in detection rate compared to the gold standard.It can provide higher quality imaging images for clinical observation of disease characteristics,provide reference for subsequent diagnosis and treatment.
