摘　　要：目的分析在肺占位性病变诊断中应用64排螺旋CT三维重建的临床价值。方法纳入2020年1月至2022年12月在我院64排螺旋CT常规扫描筛查出的60例肺占位病变患者作为研究对象,所有患者均通过64排螺旋CT常规扫描和三维重建进一步诊断,以病理结果为金标准,对64排螺旋CT常规扫描和三维重建评估肺占位性病变性质的效能进行分析,同时比较不同性质肺占位性病变的64排螺旋CT三维重建图像特点。结果64排螺旋CT常规扫描的Kappa值为0.292,64排螺旋CT三维重建的Kappa值为0.822,可见64排螺旋CT三维重建与手术病理学检查诊断一致性高于64排螺旋CT常规扫描。经对比,64排螺旋CT三维重建评估肺占位性病变性质的准确率、灵敏度和特异度高于64排螺旋CT常规扫描(P<0.05);而误诊率和漏诊率均低于64排螺旋CT常规扫描(P<0.05)。良恶性肺占位性病变的内部结构和边界比较差异具有统计学意义(P<0.05),其中,良性肺占位病变的内部结构以纯磨玻璃结节为主,边界清晰,而恶性肺占位病变的内部结构以混合密度结节为主,边界模糊。同时,恶性肺占位病变的毛刺征、分叶征、小气道改变、胸膜凹陷征和血管纠集征等图像特点的占比高于良性肺占位病变(P<0.05)。结论 64排螺旋CT三维重建在肺占位性病变诊断中的应用价值良好,可为病变定性评估提供有效依据。Objective To analyze the clinical value of applying 64-row spiral CT three-dimensional reconstruction in the diagnosis of lung occupying lesions.Methods Sixty patients with pulmonary space-occupying lesions screened by 64-row spiral CT routine scanning in our hospital from January 2020 to December 2022 were included as study subjects,all of whom were further diagnosed by 64-row spiral CT routine scanning and three-dimensional reconstruction,and the efficacy of 64-row spiral CT routine scanning and three-dimensional reconstruction in evaluating the nature of pulmonary space-occupying lesions were analyzed with the use of puncture biopsy as the gold standard,and at the same time the characteristics of 64-row spiral CT three-dimensional reconstruction images of different nature of lung occupying lesions were compared.Results The Kappa value of 64-row spiral CT conventional scan was 0.292,and the Kappa value of 64-row spiral CT three-dimensional reconstruction was 0.822,which showed that the diagnostic consistency between 64-row spiral CT three-dimensional reconstruction and surgical pathologic examination was higher than that of 64-row spiral CT conventional scanning.Upon comparison,the accuracy,sensitivity and specificity of 64-row spiral CT three-dimensional reconstruction for assessing the nature of lung-occupying lesions were higher than that of 64-row spiral CT conventional scanning(P<0.05).The misdiagnosis rate and the leakage rate for assessing the nature of lung-occupying lesions by 64-row spiral CT three-dimensional reconstruction were lower than that of 64-row spiral CT conventional scanning(P<0.05).The difference between the internal structures and boundaries of benign and malignant lung space-occupying lesions was statistically significant(P<0.05),in which the internal structures of benign lung space-occupying lesions were dominated by pure ground-glass nodules with clear boundaries,while the internal structures of malignant lung space-occupying lesions were dominated by mixed-density nodules with blurre
