[Abstract] Objective: To study the application value of MRI and CT in the clinical diagnosis of skull base bone invasion in nasopharyngeal carcinoma.Materials and Methods: To retrospectively analyze the complete clinical datas of 70 patients with nasopharyngeal carcinoma who were pathologically confirmed in our hospital from February 2018 to July 2020. The comprehensive results of the patients’ clinical symptoms, imaging data and follow-up were taken as the skull base bone invasion criteria, then to analysis of the value of CT and MRI in the diagnosis of nasopharyngeal carcinoma skull base bone invasion.Results: Bone invasion of nasopharyngeal carcinoma skull base on CT is mainly manifested as thickening of cortical bone or hyperplasia and sclerosis, single or multi-site worm-like bone destruction; MRI is mainly manifested as bone marrow high signal displaced by medium signal. Among 70 patients, 24 patients were diagnosed as skull base bone invasion with CT, the detection rate was 34.3%, of which 17 cases were invaded by multiple sites. 51 cases of skull base bone invasion were diagnosed by MRI, of which including 31 cases of multi-site invasion, the detection rate was 72.9%, the detection rate of the two examination methods was statistically different (P<0.05). Both CT and MRI examinations showed a higher incidence of the skull base bone invading the petrosal tip.Conclusions: MRI can significantly improve the detection rate in the diagnosis of nasopharyngeal carcinoma with bone invasion of the skull base, which provides imaging basis for clinicians to choose the treatment plan and is worthy of promotion.
