摘　　要：目的:探讨多层螺旋CT(Multislieces helieal Computed Tomography,MSCT)平扫联合三期增强扫描对肺癌的诊断价值。方法:选取2022年1月至2023年12月期间于本院就诊的100例疑似肺癌患者作为研究对象。患者均接受MSCT平扫和三期增强扫描,并以肺穿刺病理活检结果作为金标准,比较MSCT平扫、三期增强扫描单独及联合对肺癌的诊断结果,并计算其敏感度、特异度、准确率、阳性预测值、阴性预测值,以评估单独及联合检查对肺癌的诊断价值。结果:100例疑似肺癌患者经肺穿刺病理活检确诊72例肺癌,占比为72%(72/100)。以肺穿刺病理活检为金标准,MSCT平扫对肺癌的检出率为65.28%(47/72),三期增强扫描检出率为81.94%(59/72),联合检查对肺癌的检出率为94.44%(68/72),联合诊断的检出率高于各单独检查,且与金标准的一致性也高于各项单独检查,为0.774。MSCT平扫、三期增强联合检查的敏感度、准确率、阴性预测值均显著高于MSCT平扫和MSCT三期增强扫描单独检查(P<0.05)。结论:MSCT平扫联合三期增强扫描可有效诊断肺癌,且与金标准有较强的一致性。Objective:To evaluate the diagnostic value of multislieces helieal Computed Tomography(MSCT)combined with three-phase enhanced scan in lung cancer.Methods:100 patients with suspected lung cancer who were treated in our hospital from January 2022 to December 2023 were selected as the study objects.All patients underwent MSCT plain scan and three-phase enhanced scan.The results of lung biopsy were used as the gold standard to compare the diagnostic results of MSCT plain scan and three-phase enhanced scan alone and in combination for lung cancer.The sensitivity,specificity,accuracy,positive predictive value and negative predictive value were calculated to evaluate the diagnostic value of single and combined examination for lung cancer.Results:Out of 100 suspected patients with lung cancer,72 cases were confirmed by lung biopsy,accounting for 72%(72/100).Taking lung biopsy as the gold standard,the detection rate of MSCT plain scan for lung cancer was 65.28%(47/72),the detection rate of three-stage enhanced scan was 81.94%(59/72),and the detection rate of combined examination for lung cancer was 94.44%(68/72).The detection rate of combined diagnosis was higher than that of individual examination.And the consistency with the gold standard is also higher than each individual inspection,0.774.The sensitivity,accuracy and negative predictive value of MSCT plain scan and three-stage enhanced scan were significantly higher than those of MSCT plain scan and three-stage enhanced scan alone(P<0.05).Conclusion:MSCT plain scan combined with three phase enhanced scan can effectively diagnose lung cancer,and has a strong agreement with the gold standard.
