A retrospective comparative study was done between CT and MR in 23 patients with a tumor of the tongue, tongue base, or floor of the mouth. Tumor detection, delineation of tumor extent and the visualisation of enlarged lymph nodes was examined. Sixty per cent of the tumors were better visualised with MR, and in 21% supplementary information was acquired using MR. There were no significant differences between CT and MR regarding the visualisation of adenopathies. Despite the differences in tumor visualisation, the radiological staging according to the TNM-classification was not altered by MR.
对23例舌、舌根或口底肿瘤患者进行了CT与MR的回顾性比较研究。检查了肿瘤的检测、肿瘤范围的勾画以及肿大淋巴结的可视化情况。60%的肿瘤在MR上显示更好，21%的病例通过MR获得了补充信息。在显示腺病方面，CT和MR之间没有显著差异。尽管在肿瘤可视化方面存在差异，但根据TNM分类的放射学分期并未因MR而改变。
