摘要
目的:总结周围型肺癌的MSCT征象,以提高周围型肺癌的诊断正确率。方法:对41例经手术病理证实的周围型肺癌患者MSCT资料进行回顾性分析,并复习文献。结果:周围型肺癌表现为肺内肿块或结节,为圆形、椭圆形或不规则形,30例肿块直径≥3cm,11例直径<3cm。其中腺癌27例(1例细支气管肺泡癌),鳞状细胞癌8例,大细胞癌3例,小细胞癌3例。通过横断薄层重建及多平面重建(MPR)观察,发现二者对毛刺征、支气管截断征显示率存在显著差别(P<0.05、P<0.01);对分叶征、棘突征、血管集束征、胸膜凹陷征、磨玻璃密度影及纵隔内或肺门淋巴结增大的显示率无明显差别。结论:横断薄层重建结合多平面重建综合分析周围型肺癌的CT征像有利于提高周围型肺癌的诊断准确率。
Objective :To summarize the MSCT features of peripheral lung carcinoma, so as to improve the accuracy of the diagnosis.Methods :The Muhi-slice spiral CT features of 41 cases with operation and pathology proved peripheral lung carcinoma were studied retrospectively, and review the documents. Results :The CT features of peripheral lung carcinoma was masses or nodules in lung, the shape of peripheral lung carcinoma about circular, ellipse or irregular. in which 30 masses ≥ 3 cm in size, 11 nodule〈3 cm in size, adenocarcinoma in 27(bronchlo-loalveolar carcinoma in 1), squamous cell carcinoma in 8, big cyto carcinoma in 3, small cyto carcinoma in 3.There were difference in which show sentus sign, bronchial truncated syndrome by thin-slice axial images and multi-planar refomation(MPR)(P〈0.05, P〈0.01)and no difference in which show lobulation sign, spine-like process sign, vessel convergence sign, pleural indentation sign, ground-glass opacity, mediastinal or hilar lymphadenectasis.Conclusion :Thin-slice axial images combined with multi-planar refomation(MPR) prehensivc analysis of basic CT features is conducive to enhence the accuracy of the diagnosis of peripheral lung carcinoma.
