Abstract：Objective To analyze the specific situation of MRI and CT in the diagnosis of local invasion in patients with NPC,and the comparison accuracy does not provide guidance for the diagnosis of such patients.Methods The 40 NPC patients admitted to the hospital were taken as the research subjects.The clinical data of the patients were complete,and they all received CT and MRI examinations after admission.According to the imaging results,the two diagnostic methods were used to analyze the local invasion of NPC patients,and the skull base was analyzed.The invasion and nasopharyngeal invasion were compared,and the missed diagnosis rate and misdiagnosis rate were compared.The study date was from December 2019 to December 2021.Results(1)The comparison of the invasion of the skull base showed that the diagnostic accuracy of MTI was 95.0％,which was significantly higher than that of the CT diagnosis of 80.0％,P＜0.05;(2)The comparison of the invasion of the nasopharynx showed that the diagnostic accuracy of MTI was 97.5％,significantly higher than 85.5％of CT diagnosis,P＜0.05;(3)Comparing the missed diagnosis rate and misdiagnosis rate,it was found that the missed diagnosis rate of MRI was 2.5％,and the misdiagnosis rate was 2.5％,which were both lower than 12.5％and 7.5％of CT examination.,P＞0.05.Conclusion MRI and CT diagnosis have high diagnostic accuracy in the diagnosis of local invasion of NPC patients,but the diagnostic effect of MRI examination is better than that of CT examination,which can clarify the degree of invasion of nasopharyngeal carcinoma to the skull base and nasopharynx It can effectively reduce the risk of misdiagnosis and missed diagnosis,and can provide a more reliable and intuitive basis for clinical diagnosis and treatment of diseases,and the diagnostic value is more ideal.
