摘要
[目的]探讨CT和MRI对鼻咽癌的诊断价值。[方法]收集2003年10月到2005年1月,经病理证实的107例鼻咽癌患者,均行MRI和CT扫描,并根据临床资料和CT或MRI进行’92分期。[结果]MRI对于腔内病变的诊断以及翼腭窝、颞下窝、颈长肌、海绵窦、颅底、颈椎、咽后淋巴结、颈淋巴结等侵犯的检出要高于CT,而对鼻腔、口咽、咽旁间隙等检出与CT差别不大。根据’92分期原则,MRI相对于CT使33.6%(36/107)的病例发生了T分期改变。[结论]MRI对鼻咽癌的诊断、分期相对CT有优势。联合应用更有益。
[Purpose]To study the value of CT and MRI in diagnosis for nasopharynageal carcinoma（NPC）.[Method]From Oct.2003 to Jan ,2005,one hundred and seven NPC patients pathologically proved underwent CT and MRI examination.92 staging system was carried out based on clinical information and CT or MRI adta.[Results]MRI appeared to be more sensitive than CT in the diagnosis for intra-cavity lesion of nasopharynx and for involvememt of pterygopalatine fossa,infratemporal fossa,longus colli,cavemous sinus,skull base,cervical vertebra,retropharyngeal node,cervical node ,but no significant difference was found between MRI and CT in detecting of invasion of nasal eavity,oropharynx,and parapharyngeal space.According to 92 staging system,MRI examination made 33.6% T staging with CT changed.[Conclusion]MRI is superior to CT in diagnosis and staging for NPC,with combined application of CT and MRI even better.
