肺磨玻璃样结节的薄层CT征象与病理的相关性研究

Correlation between Thin CT Signs and Pathological Features of Pulmonary Ground Glass Nodules

目的探讨分析肺部磨玻璃样结节的薄层CT征象与病理对照研究。方法选取2017年1月至2018年1月在我院行CT扫描的肺磨玻璃样结节病患41例,对病患的术前CT图像进行回顾性分析,并将其与经病理证实为恶性肿瘤或者是癌前病变病患的病灶进行对比分析,探讨CT对肺磨玻璃样结节的诊断价值。结果本组41例病患中,浸润前病变7例,微浸润腺癌13例,浸润性腺癌21例;浸润性腺癌病患结节与微浸润或无浸润病患相比,其分叶、胸膜凹陷、边缘毛刺以及内部空泡比较多见;浸润性腺癌病患结节与微浸润或无浸润病患的磨玻璃结节体积、大小以及实性成分比较有差异(P<0.05)。结论肺磨玻璃样结节的薄层CT征象,结节的体积、大小以及实性成分比例同病理结果有着一定的关联性。

Objective To investigate the thin-slice CT signs and pathological study of the ground glass-like nodules in the lung. Methods Forty one patients with pulmonary radiculous nodular nodules who underwent CT scan in our hospital from January 2017 to January 2018 were retrospectively analyzed and confirmed by pathology. For the comparative analysis of the lesions of malignant tumors or precancerous lesions, the value of CT in the diagnosis of lung-fired glass-like nodules was explored. Results In the 41 patients, 7 had preinvasive lesions, 13 had microinvasive adenocarcinoma, and 21 had invasive adenocarcinoma. The innominate adenocarcinoma had nodules compared with those with microinvasive or noninvasive patients, pleural indentation, marginal burrs and internal vacuoles are more common; invasive adenocarcinoma patients with nodules and microinvasive or non-invasive patients with millet nodules volume, size and solid components are different（P0.05）. Conclusion The thin-slice CT signs of lungmilled nodular nodules, the volume, size and ratio of solid components of the nodules have a certain correlation with pathological results.
