核磁共振短时间反转恢复序列判断非小细胞肺癌纵隔淋巴结转移与病理诊断符合率的研究

The value of MRI-STIR in delineated mediastinal lymph nodes metastasis in non-small cell lung cancer and pathological diagnosis coincidence rate

目的:探索核磁共振短时间反转恢复序列(MRI-STIR)对判断非小细胞肺癌纵隔淋巴结转移与病理诊断的符合率.方法:回顾性分析了21例病理确诊,并行MRI检查的非小细胞肺癌病例,以MRI-STIR技术判断非小细胞肺癌纵隔转移淋巴结与病理诊断的符合率.结果:MRI-STIR诊断正确22个淋巴结,符合率为62.9%(22/35),MRI-STIR判断非小细胞肺癌纵隔转移淋巴结的敏感度为52.4%(22/42),特异度为88.8%(103/116).结论:M R I-S T I R对于判断非小细胞肺癌纵膈淋巴结转移具有一定临床价值,但也存在假阴性及假阳性,为提高诊断准确性,需同其他检查手段结合.

Objective To explore the coincidence rate of mr-stir for mediastinal lymph node metastasis and pathological diagnosis of non-small cell lung cancer.Methods A retrospective analysis of 21 cases of non-small cell lung cancer with pathologic diagnosis,combined with MRI,To determine the coincidence rate of mediastinal metastatic lymph nodes and pathological diagnosis of non-small cell lung cancer.Results MRI-STIR Correct diagnosis of 22 lymph nodes,coincidence rate of 62.9%(22/35),The sensitivity of MRI-STIR based on single lymph node analysis was 52.4%(22/42),specificity was 88.8%(103/116).Conclusion MRI-STIR is of certain clinical value for the determination of mediastinal lymph node metastasis of NSCLC,but there are also false negative and false positive,which should be combined with other examination methods to improve the diagnostic accuracy.
