(MR findings) Magnetic resonance (MR) imaging appearances were investigated before and after radiotherapy. In patients without recurrence, MR appearance of the mobile tongue showed characteristic patterns after radiotherapy. An enhanced area equivalent to the submandibular gland was shown in 16 of 49 patients without recurrence. The remaining 33 patients showed relatively weak or no enhancement compared to those of submandibular gland.(FDG-PET findings) After definitive radiotherapy with interstitial implants, false-positive appearances were observed probably due to ill-balanced movement of the tongue.(Re-evaluation of diagnostic imaging for neck lymph node) Diagnostic criteria should be customized for each institution.

（MR）观察放疗前后磁共振（MR）影像学表现。在无复发的患者中，放射治疗后活动舌的MR表现为特征性模式。49例患者中有16例无复发，其面积增大相当于下颌腺。其余33例患者与颌下腺相比表现出相对较弱或无增强。（FDG-PET结果）在使用间质种植体进行明确放射治疗后，可能由于舌头运动不平衡而观察到假阳性外观。（颈部淋巴结诊断影像的再评价）诊断标准应根据不同的机构进行定制。
