摘　　要：目的探讨多层螺旋CT图像后处理技术在肺部浸润前与浸润性病变患者中的鉴别诊断价值。方法回顾42例肺部浸润前病变(A组)与56例浸润性病变(B组)患者的资料。采用GE64排螺旋CT进行扫描检查,并进行后处理。比较2组患者CT征象,以受试者工作特征(receiver operating characteristic,R0C)曲线分析病灶直径和多层螺旋CT图像后处理技术对浸润前病变和浸润性病变的效能。结果2组病灶边缘、病变周边征象、病灶直径比较差异有统计学意义(P<0.05),即浸润性病变中分叶/毛刺、血管集束征多见,浸润性病变病灶直径大于浸润前病变(P<0.05);病灶直径对肺部浸润前病变和浸润性病变鉴别诊断的R0C分析显示,病灶直径的最佳截断点为12.77 mm,灵敏度、特异度和曲线下面积(AUC)分别为76.19%、80.36%和0.810;多层螺旋CT图像后处理技术对肺部浸润前病变和浸润性病变鉴别诊断的R0C分析显示,灵敏度、特异度和AUC分别为76.19%、86.43%和0.901。结论出现分叶/毛刺、血管集束征、病灶直径>12.77 mm均可提示肺部浸润性病变,多层螺旋CT图像后处理技术用于肺部浸润前与浸润性病变患者鉴别诊断的效能更高。Objective To explore the differential diagnosis value of multi-slice spiral CT image post-pro-cessing technology in patients with preinvvasive lesions and invasive lesions.Methods The data of 42 patients with preinvvasive lesions(group A)and56 patients with invasive lesions admitted to the hospital(group B)were reviewed.The GE64 row spiral CT was used for scanning inspection,after the images scan and post processing were completed.The CT signs of the two groups of patients were compared,the receiver operating characteristic(ROC)curve was used to analyze the effect of lesion diameter and multi-slice spiral CT image post-processing technology on preinvvasive and invasive lesions.Results There were statistically significant difference in lesion edge,peripheral signs and lesion diameter between the two groups(P<0.05),that is,leaf/burrs of invasive lesions and vascular bundling signs were more common,the size of the infiltrating lesion was larger than that before the invasion(P<0.05).ROC analysis of the differential diagnosis of lesion diameter for pre-infiltration lesions and invasive lesions shows that the optimal cutoff point for lesion diameter was 12.77 mm,sensitivity,specificity and area under curve(AUC)were 76.19%,80.36%and 0.810,respectively.ROC analysis of the differential diagnosis of multi-slice spiral CT image post-processing technology for pre-infiltration lesions and invasive lesions shows that the sensitivity,specificity and AUC were 76.19%,86.43%and 0.901,respectively.Conclusions The presence of leaf/burr,vascular bundling sign,and lesion diameter>12.77mm can indicate lung infiltrating lesions,in the differential diagnosis of patients with preinvvasive lesions and invasive lesions,the multi-slice spiral CT image post-processing technique is more effective.
