FGGO多层螺旋CT征象与其性质鉴别诊断价值分析

Analysis of Manifestations of FGGO in Multi-slice Spiral CT and Differential Diagnosis for Its Nature

目的研究FGGO在多层螺旋CT(MSCT)征象表现,对其性质进行鉴别,分析MSCT在FGGO临床诊断价值。方法收集本院2017年7月至2019年4月收治的75例肺部FGGO患者的临床资料,对比良、恶性病变的病灶形态,边缘是否光整,边界是否清楚,常见征象表现以及病灶类型分型。结果良、恶性病变病灶形态、边缘、常见征象比较存在明显差异(P<0.05),良性病变病灶形态以圆形或类圆形为主,边缘光整,大部分边界清楚;恶性病变病灶大多呈不规则形态,边缘以不光整为主,出现"毛刺征",边界大部分清楚,少部分呈现模糊状态;良性病变无胸膜"凹陷征"和血管"纠集征","支气管征"与"分叶征"分别出现3例,恶性病变主要出现"支气管征"、胸膜"凹陷征"、"分叶征"(P>0.05);MSCT检查对良、恶性FGGO总诊断正确率为90.89%,与病理学检查结果相比,两者比较无差异(P<0.05)。结论MSCT可反映病变组织内结构变化、病理改变以及血管征象,对判断FGGO性质判断有着重要的参考价值。

Objective To study the manifestations of FGGO in multi-slice spiral CT(MsCT),to identify its nature,and to analyze the clinical diagnostic value of MsCT for FGGO.Methods The clinical data of 75 patients with pulmonary FGGO admitted from July 2017 to April 2019 in our hospital were collected.The shape of the lesion was compared between good and malignant lesions,whether the edge was smooth,the boundary was clear.Common signs and lesion types were compared.Results There were significant differences in the shape,margins and common signs between benign and malignant lesions(P<0.05).The lesions shape of benign lesions were mainly round or suborbicular,with smooth edges and most of the borders were clear.The lesions shape of malignant lesions were mostly irregular,the edge was mainly smooth and tidy,a small number of edges showed burrs.Most of the borders were clear,and a few of borders were fuzzy.There were no pleural indentation signs and vascular entanglement in benign lesions.There were 3 cases with bronchial sign and lobulated sign respectively.The main signs of malignant lesions were bronchial sign,pleural indentation sign and lobulated sign(P>0.05).The overall diagnostic accuracy of MsCT was 93.33%for benign and malignant FGGO diseases.Compared with Compared with the results of the pathological examination,there was no difference between the two examination(P<0.05).Conclusion MsCT can reflect structural changes,pathological changes and vascular signs in diseased tissues,and has important reference value for judging the nature of FGGO.
