摘　　要：目的探讨多螺旋CT(multi-spiral CT,MSCT)在早期肺癌诊断中的特异度、灵敏度。方法选取2018年1月—2023年9月江苏省徐州医科大学附属沭阳医院影像科收治的74例疑似早期肺癌患者为研究对象。以病理检查结果为金标准,所有患者均行常规CT、MSCT检查,对比常规CT与MSCT对早期肺癌的诊断结果和诊断效能。结果病理检查诊断阳性62例,阴性12例;常规CT诊断阳性58例,阴性16例;MSCT诊断阳性62例,阴性12例。MSCT诊断的灵敏度为98.39%(61/62),准确度为97.30%(72/74),高于常规CT的87.10%(54/62)、83.78%(62/74),差异有统计学意义(χ^(2)=4.313、7.889,P均<0.05)。两种检查方法的特异度比较,差异无统计学意义(P>0.05)。结论与常规CT相比,MSCT对早期肺癌的诊断准确度、灵敏度均更高,具有一定的临床应用价值。Objective To explore the specificity and sensitivity of multi-spiral CT(MSCT)in the diagnosis of early lung cancer.Methods A total of 74 patients with suspected early lung cancer admitted to the Department of Imaging of Shuyang Hospital Affiliated to Xuzhou Medical University from January 2018 to September 2023 were selected as the study subjects.With the results of pathological examination as the gold standard,all patients underwent conventional CT and MSCT examination,and the diagnostic results and diagnostic efficacy of conventional CT and MSCT for early lung cancer was compared.Results Pathological diagnosis was positive in 62 cases and negative in 12 cases.Conventional CT diagnosis was positive in 58 cases and negative in 16 cases.MSCT diagnosis was positive in 62 cases and negative in 12 cases.The sensitivity and accuracy of MSCT were 98.39%(61/62)and 97.30%(72/74),which were higher than 87.10%(54/62)and 83.78%(62/74)of conventional CT,and the differences were statistically significant(χ^(2)=4.313,7.889,both P<0.05).There was no significant difference in the specificity between the two methods(P>0.05).Conclusion Compared with conventional CT,MSCT has higher diagnostic accuracy and sensitivity for early lung cancer,and has certain clinical application value.
