摘　　要：３５例鼻咽癌作了颈部ＭＲＩ检查，临床触诊和ＭＲＩ分别检出了４８枚和８２枚阳性淋巴结，其差别主要是ＭＲＩ能发现常规触诊不能发现的咽后区和部分上颈深区转移淋巴结；两种方法测量的淋巴结大小也有所不同，使ＴＮＭ分期中Ｎ的期别有可能发现变化；转移淋巴结在Ｔ１上表现为与肌肉较一致的等信号，Ｔ２像上为类似脂肪组织的高信号但不均匀，Ｇｄ－ＤＴＰＡ增强后出现明显的不均匀强化现象，与鼻咽部原发灶有类似的表现。MRI was executed in 35 NPC Patience before radiotherapy. By clinical Palpation, 48 cervical lymphnodes were suspected involvement in MRI, because more adenopathy were detected in lateral retropharyngeal and high intemal jugular regions there were 82 positive nodes. By the two diagnostic methods, the different size of lymphnodes were measured, so the N stage was changed also. It exhibited isointense with surrounding muscle on the T1 - weighted and markedly in homogentity hyperintense on the T2 - weighted images, and there were clearly enhancement of the lesion after Gd - DTPA administration.
