The Diagnosis Value of MRI and CT Plain Scan/Enhancement Image on Nasopharyngeal Carcinoma

Objective To study diagnosis value of the magnetic resonance imaging(MRI)on clinical diagnosis and treatment in nasopharyngeal carcinoma.Methods 245 cases of pathologically confirmed nasopharyngeal carcinoma patients with MRI and CT plain scan/enhancement imaging data.Results In 245 cases of nasopharyngeal carcinoma,MRI scan/enhanced displayed paranasopharyngeal extension,oropharynx,retropharyngeal lymph nodes,skull base,sinus,cavernous sinus/brain,etc.The detectable rate of MRI was higher than that of CT,the difference was statistically significant(P0.05);the detectable rate of cervical lymph node metastasis of MRI plain scan was higher than that of CT,the difference was statistically significant(P0.05).However,the detectable rate of cervical lymph node metastasis between enhancement MRI and CT was no significant difference(P0.05);the detectable rate of nasal metastasis between MRI and CT enhancement scan was not statistical significance(P0.05).Conclusion MRI can clearly show that nasopharyngeal carcinoma tissue,adjacent structures,retropharyngeal lymph node metastasis,and has great value in the diagnosis and radiation therapy target orientation of nasopharyngeal carcinoma.
