Objective Exploring the clinical diagnostic value of MRI and CT in detecting skull base bone invasion in nasopharyngeal carcinoma.Methods A total of 72 patients with nasopharyngeal carcinoma suspected of skull base bone invasion admitted to Wuwei People's Hospital from February 2022 to April 2023 were selected as the study objects.MRI and CT were performed before surgery and biopsy to compare the diagnostic efficacy of the two methods for skull base bone invasion.Results Among 72 patients with nasopharyngeal carcinoma suspected of skull base bone invasion,58 cases(80.56%)were confirmed as skull base bone invasion by postoperative histopathological diagnosis,and 14 cases(19.44%)were confirmed as no skull base bone invasion.CT detected 40 positive cases and 32 negative cases.MRI was positive in 49 cases and negative in 23 cases.The sensitivity(81.03%)and accuracy(81.94%)of MRI were significantly higher than those of CT(62.07%)and 63.89%(P＜0.05).The sensitivity(96.55%)and accuracy(95.83%)of the combined diagnosis of skull base bone invasion were significantly higher than those of CT and MRI alone(P＜0.05).The total accuracy of MRI in detecting skull base bone invasion was higher than that of CT,and the difference was statistically significant(P＜0.05).Conclusion MRI scan can more sensitively detect skull base bone invasion in patients with nasopharyngeal carcinoma.Compared with CT examination,the detection rate is relatively high,which helps to clarify the location of bone invasion,and the combined detection can further improve the diagnostic accuracy.
