摘要
目的:探讨MRI显示与肺癌手术有关结构被侵程度的能力,制定MRI判断肺癌能否手术的标准。方法:术前2周内均行MRI、纤维支气管镜检查,并经手术证实为中心型肺癌病人24例,对两种检查和手术证实结果进行回顾性对比分析。结果:MRI显示叶支气管闭塞准确率16/20例,显示叶支气管狭窄准确率4/4例。病变与纵隔大血管贴邻组手术分离率7/7例,粘连组为12/17例,包绕组为0/4例。结论:MRI显示叶以上支气管狭窄、阻塞可靠。病变贴邻大血管者手术容易分离;病变和大血管仅为粘连者手术均可分离,若粘连合并大血管变形、狭窄则手术分离困难;病变包绕大血管时则手术分离相当困难。
Objective:To establish a MRI criterion by which it can be judged whether operation is feasible in lung cancers.Clinical material and method:24 patients with central lung cancers were studied retrospectively MRI was confirmed with bronchoscopy preoperatively in all patients.Result:MRI accuracy rate was 16/20 in cases showing lobar bronchial obstruction,4/4 for cases showing stenosis.In MRI images,the relationship between masses and great vessels in mediastinum was classified into three types as nestling,adhering and surrounding.In nestling group,surgery was successful in 7/7.In adhering group resectability rate was 12/17.Conclusion:The higher resectability rate can be achieved in patients with MRI demonstrated nestling or moderately adhering.Severe adhesion and mass surrounding the great vessels in mediastium are not suitable for surgery.
