摘　　要：目的:探讨分析早期肺腺癌的高分辨率CT(HRCT)血管征在早期肺腺癌病理亚型分型的关系。方法:回顾性分析87例经手术切除肺早期肺腺癌结节患者的HRCT资料,按照最新的肺腺癌病理分类标准将其分为2组:浸润前组共31例,包括不典型腺瘤样增生(AAH)11例、原位腺癌(AIS)20例;浸润性腺癌(IAC)组56例,包括微浸润腺癌(MIA)组23例;浸润性腺癌(IAC)组33例。对各组早期肺腺癌的血管与病灶进行评估并作统计学分析。结果:高分辨率CT(HRCT)血管征在示浸润前组与浸润组间比较差异有统计学意义(P<0.01),但在浸润前组中不典型腺瘤样增生与原位腺癌间比较无显著差异(P>0.05)。结论:高分辨率CT(HRCT)血管征可作为区分浸润前病变、浸润性病变的重要CT影像特征。Objective:To explore the relationship between high resolution CT(HRCT) vascular signs and pathologic subtypes of early lung Adenocarcinoma. Methods:HRCT data of 87 patients with Lung Adenocarcinoma nodules were retrospectively analyzed. According to the latest pathologic classification of Lung Adenocarcinoma, 87 patients were divided into 2 groups: pre-invasive Group(31 cases), there were 11 cases of atypical adenomatous hyperplasia(AAH), 20 cases of Adenocarcinoma in Situ(AIS), 56 cases of invasive Adenocarcinoma(IAC), including 23 cases of microinvasive Adenocarcinoma(MIA), and 33 cases of invasive Adenocarcinoma(IAC). The vessels and Foci of early lung Adenocarcinoma in each group were evaluated and statistically analyzed. Results:High Resolution CT(HRCT) vascular signs showed significant difference between pre-invasive Group and Invasive Group(P<0.01), but there was no significant difference between Atypical Adenomatous Hyperplasia and Adenocarcinoma in situ in pre-invasive Group(P>0.05). Conclusion:High Resolution CT(HRCT) vascular signs can be used as an important imaging feature to distinguish pre-invasive lesions from invasive lesions.
