【摘要】：目的探討CT表現(xiàn)為混合磨玻璃結(jié)節(jié)的肺原位腺癌(AIS)、微浸潤(rùn)腺癌(MIA)和浸潤(rùn)性腺癌(IAC)中實(shí)性成分的CT表現(xiàn)及病理特征,分析肺混合磨玻璃結(jié)節(jié)中實(shí)性成分對(duì)AIS、MIA和IAC的定性診斷價(jià)值,為臨床選擇治療方法提供參考。資料與方法回顧性分析CT表現(xiàn)為混合磨玻璃結(jié)節(jié)、并經(jīng)手術(shù)病理證實(shí)的18例AIS、53例MIA及28例病灶最大徑≤2 cm的IAC患者,分析3組病灶中的實(shí)性成分的CT表現(xiàn),并與病理結(jié)果進(jìn)行對(duì)照。結(jié)果 AIS病灶中實(shí)性成分以點(diǎn)狀或多邊形多見(jiàn),大小分布面較廣,實(shí)性結(jié)節(jié)常單發(fā)(17例,94.44%),位于病灶中心(14例,77.78%),邊界清晰(16例,88.89%),與同層面血管密度相仿(13例,72.22%);MIA實(shí)性成分以圓形及橢圓形居多(33例,62.26%),大小≤5 mm(48例,90.57%),呈偏心性多點(diǎn)分布(45例,84.90%),邊界欠銳利(40例,75.47%),密度稍低于同層面血管(34例,64.15%);IAC病灶中實(shí)性成分以不規(guī)則形多見(jiàn)(21例,75.00%),大小5 mm(24例,85.71%),呈偏心性生長(zhǎng)(20例,71.43%),并呈多結(jié)節(jié)融合,邊界欠銳利(15例,53.57%)。3組病灶中的實(shí)性成分CT表現(xiàn)差異均有統(tǒng)計(jì)學(xué)意義(P0.01)。結(jié)論根據(jù)肺混合磨玻璃結(jié)節(jié)中實(shí)性成分在CT影像上的不同表現(xiàn),能在一定程度上預(yù)測(cè)肺混合磨玻璃結(jié)節(jié)的病理分型和預(yù)后,并指導(dǎo)臨床處理原則。
[Abstract]:Objective to investigate the CT features and pathological features of solid components in mixed milled glass nodules (AISA) and invasive adenocarcinomas (IAC), and to analyze the diagnostic value of solid components in mixed milled glass nodules for AISMIA and IAC.To provide a reference for clinical selection of treatment methods.Materials and methods CT findings of mixed ground-glass nodules were retrospectively analyzed in 18 patients with MIA and 28 patients with IAC whose maximum diameter was less than 2 cm. Ct findings of solid components in 3 groups were analyzed.The results were compared with pathological results.Results the solid components of AIS lesions were mostly punctate or polygonal, and the size of the lesions was very wide.瀹炴，
