摘　　要：目的:观察CT血管造影三维重建检查对肺部占位病变良恶性的鉴别诊断价值。方法:选取2021年1月至2023年12月该院收治的80例肺部占位病变患者进行横断面研究,患者均行常规CT检查、CT血管造影三维重建检查以及病理学检查,以病理学检查结果作为金标准,比较常规CT检查、CT血管造影三维重建检查在鉴别诊断肺部占位病变良恶性中的效能,采用Kappa一致性检验分析常规CT检查、CT血管造影三维重建检查诊断结果与病理学检查结果的一致性。结果:病理学检查结果显示,80例肺部占位病变患者恶性35例,良性45例;CT血管造影三维重建检查鉴别诊断肺部恶性占位病变的特异度为95.56%,高于常规CT检查的82.22%,差异有统计学意义(P<0.05);CT血管造影三维重建检查鉴别诊断肺部恶性占位病变的准确度为96.25%,高于常规CT检查的81.25%,差异有统计学意义(P<0.05);Kappa一致性检验显示,CT血管造影三维重建检查鉴别诊断肺部占位病变良恶性的结果与病理学检查结果的一致性(Kappa=0.925,P<0.05)高于常规CT检查与病理学检查结果的一致性(Kappa=0.430,P<0.05);CT血管造影三维重建检查与常规CT检查诊断肺部恶性占位病变的灵敏度比较,差异无统计学意义(P>0.05)。结论:CT血管造影三维重建检查诊断恶性肺部占位病变的准确度、特异度以及与病理学检查结果的一致性均高于常规CT检查。Objective:To observe differential diagnostic value of CT angiography three-dimensional reconstruction for benign and malignant pulmonary space-occupying lesions.Methods:A cross-sectional study was conducted on 80 patients with pulmonary space-occupying lesions admitted to this hospital from January 2021 to December 2023.All patients underwent conventional CT examination,CT angiography three-dimensional reconstruction and pathological examination.Using the results of pathological examination as the gold standard,the efficacies of conventional CT examination and CT angiography three-dimensional reconstruction in the differential diagnosis of benign and malignant pulmonary space-occupying lesions were compared.Kappa consistency test was used to analyze the consistency between the diagnostic results of conventional CT examination,CT angiography three-dimensional reconstruction and pathological examination.Results:The pathological examination showed that there were 35 cases of malignant lesions and 45 cases of benign lesions in the 80 patients with pulmonary space-occupying lesions.The specificity of CT angiography three-dimensional reconstruction in the diagnosis of malignant pulmonary space-occupying lesions was 95.56%,which was higher than 82.22%of conventional CT examination,and the difference was statistically significant(P<0.05).The accuracy of CT angiography three-dimensional reconstruction in the diagnosis of malignant pulmonary space-occupying lesions was 96.25%,which was higher than 81.25%of conventional CT examination,and the difference was statistically significant(P<0.05).Kappa consistency test showed that the consistency between the differential diagnosis of benign and malignant pulmonary space-occupying lesions by CT angiography three-dimensional reconstruction and pathological examination(Kappa=0.925,P<0.05),which was higher than(Kappa=0.430,P<0.05)of conventional CT examination and pathological examination.There was no significant difference in the sensitivity of CT angiography three-dimensional recon
