目的：研究多种病理类型肺部磨玻璃结节的CT表现。方法将104例CT影像学表现为肺部磨玻璃结节的患者分为三组院浸润前病变组25例、微浸润腺癌组(MIA)42例、浸润性腺癌组(IAC)37例,比较三组患者病灶的大小、三维和二维比率、病灶形状等指标。结果①浸润前病变患者的CT表现多为纯磨玻璃结节,MIA患者多表现为纯磨玻璃结节或混合密度磨玻璃结节,IAC患者多表现为混合密度磨玻璃结节；②从浸润前病变到微浸润腺癌再到浸润性腺癌,病灶边缘毛刺、分叶,内部空泡和胸膜凹陷征的比率逐渐增加；③MIA患者与IAC患者的CT表现在病灶大小、密度、实性成分、形状、边缘毛刺、内部空泡、胸膜凹陷等方面差异明显(P<0.05)；榆浸润前病变患者与MIA患者在病变密度、边缘毛刺、分叶、实性成分方面差异有统计学意义(P<0.05)。结论对磨玻璃结节的CT影像学特征进行分析有利于诊断和鉴别肺部浸润前病变、浸润性腺癌、微浸润腺癌,值得临床推广应用。

Objective To explore the CT features of ground-glass nodules. Methods A total of 104 cases of GGN le-sions were divided into three groups, 25 cases in preinvasive lesion group, 42 cases in minimally invasive adeno-careinoma group(MIA), 37 cases in invasive adenocarcinoma group (IAC), the lesion size, 3-dimensional ratio, 2-dimen-sional ratio, shape were analyzed and compared with pathological. Results ①All preinvasive lesions presented as pure GGN on CT image, MIA presented as pure GGN or mixed GGN on CT image, IAC most presented as mixed GGN on CT image; ②Speculation, lobulation, air-containing space and pleural indentation displayed gradually increasing from preinvasive lesions to MIA and IAC; ③There were statistically significant differences in lesion size, CT density, shape between the MIA and IAC groups (P<0.05); ④There were statistically significant differences in CT density values and long diameters of solid component of the lesions between the preinvasive lesion group and MIA group (P<0.05). Con-clusion Comprehensive analysis of the CT image features of GGNs, especially the solid component in the lesions, may help to the preoperative and differential diagnosis of preinvasive lesions, MIA and IAC, which is worth promoting the clinical application.
