【摘要】：目的探讨多层螺旋CT(MSCT)在肺局灶性亚厘米磨玻璃结节(f GGO)诊断中的临床价值。方法分析95例亚厘米f GGO患者的MSCT检查资料,并与病理诊断结果相对照,比较不同病理类型f GGO病灶大小、内部实性成分大小、混合型磨玻璃结节(m GGO)比例、和胸膜凹陷、病灶形状、分叶、毛刺、空泡和边界情况。按照病灶与周围血管的关系分为3型,分析不同病理类型f GGO与血管关系分型。结果 95例患者病灶最小为4.1 mm,最大为9.9 mm。浸润前组与腺癌组病变大小、实性成分大小、m GGO和分叶征所占比例差异有统计学意义(P0.05),而胸膜凹陷、病灶形状、毛刺、空泡和边界情况差异无统计学意义(P0.05),良性组除分叶所占比例与腺癌组差异有统计学意义外,其余征象与腺癌组差异均无统计学意义(P0.05),按照f GGO与血管关系分型,良性组均为Ⅰ型和Ⅱ型,浸润前组Ⅲ型10例(25.6%),腺癌组Ⅲ型17例(39.5%),浸润前组、腺癌组Ⅲ型所占比例均高于良性组(P0.05)。结论肺内亚厘米f GGO术前定性诊断难度较大,病灶的MSCT形态特点及其与周围血管的关系对病变性质的判断有一定价值。
[Abstract]:Objective to evaluate the clinical value of multilayer spiral CTT in the diagnosis of focal subcentimeter milled glass nodules (f GGO.). Methods the MSCT findings of 95 patients with subcentimeter f GGO were analyzed and compared with pathological findings. The size of f GGO lesions, the size of internal solid components, the proportion of mixed milled glass nodules, and pleural cavity, shape, lobulation, burr were compared among different pathological types. According to the relationship between the lesions and the peripheral vessels, the relationship between the lesions and the vessels was classified into 3 types. Results the lesions of 95 patients were the smallest of 4.1 mm and the maximum of 9.9 mm. The size of the lesions in the preinvasive group and the adenocarcinoma group was 9. 9 mm, and the size of the lesions in the preinvasive group and the adenocarcinoma group was 9. 9 mm. There were significant differences in the proportion of solid component size GGO and lobulation sign (P 0.05), but pleural depression, lesion shape, burr, etc. There was no significant difference in cavitation and boundary conditions (P 0.05). Except for the proportion of lobulation in benign group and adenocarcinoma group, there was no significant difference between benign group and adenocarcinoma group (P 0.05). According to the relationship between f GGO and vascular type, there was no significant difference between benign group and adenocarcinoma group. The proportion of type 鈪，
