Comparison of CT and MRI in diagnosis of nasopharyngeal

Objective To compare the detection rate of nasopharyngeal carcinoma with CT scan and MRI,evaluate the value in the diagnosis of nasopharyngeal carcinoma.Methods 38 patients from March 2011 to September 2012 who were definitely diagnosed with nasopharyngeal at pathology tests were selected,comparative analysis was carried out to study their CT and MRI test results,and compare the two imaging methods for detection rate in the diagnosis of nasopharyngeal.Results The detection rate of CT scan was 42.1％ for the imaging diagnosis of nasopharyngeal invasion while that of MRI was 71.1％,the detection rate of CT scan was 36.8％ for the imaging diagnosis of local invasion to basis cranii while that of MRI was 54.2％,there was statistical difference between CT and both in the diagnosis of nasopharyngeal (P＜0.05).Conclusion MRI has remarkable advantage in diagnosis of nasopharyngeal with more convincing MRI results,it is much more valuable for patients with nasopharyngeal.
