喉咽、颈段食管癌的磁共振表现

Magnetic resonance imaging of hypopharyngeal and cervical esophageal cancer

通过对17例喉咽、颈段食管癌的食管吞钡造影与磁共振（MRI）检查结果进行对比分析。资料表明，食管吞钡造影不能显示肿物浸润周围组织结构的情况，故难作出正确的TNM分期；MRI是显示肿瘤三维形态、肿瘤与邻近结构关系的有效和可靠的技术手段。提示MRI对喉咽、颈段食管癌的诊断、TNM分期和技术治疗的选择，均具有重要的指导意义。

Imaging by MR (MRI) and esophageal barium meal of 17 cases of hypopharyngeal and cervical esophageal cancer were analyzed. The results indicate that esophageal barium meal can not demonstrate the invading of neoplasms to the adjacent structure. Therefore, it is difficult to use the only data of esophageal barium meal for TNM staging. The results also indicate that MRI is more useful and reliable in assessing the three dimensional structure and the neoplasms invading to the adjacent structure. This results suggest that MRI is that useful in determing the diagnosis, TNM staging and the determing the appropriate operative therapy for hypopharyngeal and cervical esophageal cancer.
