摘　　要：目的分析肺微浸润性腺癌（MIA）的高分辨率CT（HRCT）表现,提高MIA的CT诊断准确性。方法收集经手术病理证实的84例患者共92个MIA,术前均行常规HRCT扫描。结果 92个MIA最大长径0.4~2.6 cm,其中纯磨玻璃密度结节（p GGN）56个（61%）,病灶密度（-534.40±137.71）HU;混合磨玻璃密度结节（m GGN）36个（39%）。54例患者为单发病灶,30例患者为多发病灶（共38个MIA）;空泡征5个,结节边缘清晰84个,分叶征32个,血管聚集征65个,血管供应征（血管增粗）40个,细支气管扩张征9个,胸膜牵拉、凹陷31个。结论 MIA多数表现为p GGN,CT值（-534.40±137.71）HU,少部分表现为m GGN,病灶多〈2 cm,单发、边缘清楚,伴有血管聚集征。HRCT有助于MIA的显示和早期诊断。Objective To improve the diagnostic accuracy of minimally invasive adenocarcinoma（MIA） with the analysis of high-resolution CT images. Methods 84 patients with 92 cases of MIA proven by surgery and histopathology were reviewed. All cases performed with HRCT scan before surgery. Results Of 92 cases of MIA, the longest diameter range from 0.4-2.6 cm, 56 cases were pure ground-glass nodules（p GGNs） with the density（-534.40±137.71）HU, 36 cases were mixture ground-glass nodules（m GGNs）. 54 patients showed single lesion, 30 patients showed multiple lesions（total of 38 cases with MIA）. 5 cases had vacuole sign, 84 cases had clear margin, 32 cases had lobulation sign, 65 cases had vessels gathered, 40 cases had vascular supply positive, 9 cases had bronchiolectasis sign, and 31 cases had pleura indentation. Conclusion Most of MIA manifested as p GGNs, CT value（-534.40±137.71）HU. A small part of cases manifested as m GGNs. The lesion is always less than 2 cm, single, clear margin, with vessels gathered. HRCT can contribute to display and early diagnosis of MIA.
