摘要 目的对鼻咽癌侵犯周围结构进行MRI与CT比较分析,评价MRI相对于CT对1992福州分期产生的影响。方法收集经病理证实初诊鼻咽癌42例,在CT和MRI上分别评价各个解剖部位的受侵情况;并按照RTOG推荐的分区标准,将颈部分为Ⅰ-Ⅵ个区进行评判;按照1992福州分期,作CT与MRI的对比。结果MRI对于口咽、颅底骨质、海绵窦、鼻窦、颞下窝等侵犯的检出率明显高于CT;MRI使47.6%的T期发生了改变,23.8%的N分期发生了改变,26.2%的临床分期发生改变。结论MRI在显示鼻咽癌对周围结构的侵犯方面有着巨大的优势,它能为临床准确地勾画出放疗靶区,指导合理的治疗。为了让MRI在鼻咽癌诊断和治疗中发挥更大的作用,有必要尽早出台MRI的临床分期标准。 Objective To analyze CT and MRI in nasopharyngeal carcinoma encroaching on around composition, And to evaluate the impaction 1992 fuzhou staging system by using MRI relative CT. Methods A total of 42 cases with NPC of histologically diagnosed were evaluated each encroached on situation about dissect position at CT and MRI. According to standard of RTOG recommend, Neck was judged from Ⅰ to Ⅵ area. According to 1992 fuzhou staging system, To Comparison about CT and MRI. Results MRI was significantly superior to CT in the detection of oropharynx, base of skull, cavernous sinus, nasal sinuses, infratemporal fossa. According to the MRI data, 47. 6% of T classification, 23. 8% of N classifieation,26.2% of clinical stage were shifted. Conclusion MRI has great superiority in nasopharyngeal carcinoma encroaching on around composition. It could accurate display radiotherapy target area for clinical, and to guide rational treating. For MRI elaborate the greatest affecting in diagnose and cure. We must draw up a standard for clinical staging system of MRI as early as we can.
