摘　　要：目的:分析CT血管造影联合三维重建对肺部占位性病变良恶性的诊断价值。方法:回顾性收集2020年1月-2022年6月期间本院医学影像中心收治的120例经组织活检或手术病理检查确诊的肺部良恶性病变患者的临床资料。所有患者组织活检或手术病理检查均先行CT血管造影联合三维重建检查。根据组织活检或手术病理检查结果将患者分为恶性组和良性组。分析CT血管造影、CT血管造影联合三维重建对肺部良恶性病变的诊断效能。采用Kappa检验CT血管造影联合三维重建与手术检查或组织活检诊断结果的一致性。评估CT血管造影联合三维重建对肺部占位性病变的诊断价值。结果:手术检查或组织活检结果显示67例良性病变,53例恶性病变。CT血管造影检验肺部良恶性病变的灵敏度、准确度均显著低于CT血管造影联合三维重建(P<0.05)。经Kappa一致性检验,CT血管造影检出结果与病理检查结果具有较强一致性(Kappa=0.867);CT血管造影联合三维重建检查结果与病理检查结果具有强一致性(Kappa=0.949)。恶性组患者重建肺部支气管动脉数量显著多于对照组、左右侧支气管动脉内径显著大于良性组(P<0.05)。结论:CT血管造影联合三维重建对肺部占位性病变具有较高的诊断价值。Objective:To analyze the diagnostic value of CT angiography combined with 3D reconstruction in benign and malignant lung space-occupying lesions.Methods:The clinical data of 120 patients with benign and malignant lung lesions confirmed by biopsy or surgical pathological examination admitted to the Medical Imaging Center of our hospital from January 2020 to June 2022 were retrospectively collected.CT angiography combined with 3D reconstruction were performed in all patients for tissue biopsy or surgical pathology.The patients were divided into malignant group and benign group according to the results of biopsy or surgical pathological examination.To analyze the diagnostic efficacy of CT angiography and CT angiography combined with 3D reconstruction in benign and malignant lung lesions.Kappa was used to test the consistency between CT angiography combined with 3D reconstruction and surgical examination or tissue biopsy.To evaluate the diagnostic value of CT angiography combined with 3D reconstruction in space-occupying lung lesions.Results:Surgical examination or tissue biopsy showed 67 benign lesions and 53 malignant lesions.The sensitivity and accuracy of CT angiography in detecting benign and malignant lung lesions were significantly lower than that of CT angiography combined with 3D reconstruction(P<0.05).After Kappa consistency test,the results of CT angiography showed strong consistency with those of pathological examination(Kappa=0.867).The results of CT angiography combined with 3D reconstruction were strongly consistent with those of pathological examination(Kappa=0.949).The number of reconstructed pulmonary bronchial arteries in the malignant group was significantly higher than that in the control group,and the internal diameter of left and right bronchial arteries in the benign group was significantly higher than that in the benign group(P<0.05).Conclusion:CT angiography combined with 3D reconstruction is valuable in the diagnosis of space-occupying lung lesions.
