摘　　要：目的:分析CT与MRI对于诊断鼻咽癌的临床价值。方法:选取2020年1月—2024年1月在汶上县人民医院收治的98例疑似鼻咽癌的患者作为本次研究的对象,均行CT与MRI检查,并以病理检查结果作为诊断的“金标准”,评估CT与MRI对鼻咽癌诊断的价值。结果:病理学检查显示,80例患者确诊为鼻咽癌,CT检查提示70例患者为鼻咽癌;MRI检查提示76例患者为鼻咽癌;MRI诊断鼻咽癌的准确率(91.84%)高于CT诊断(79.59%),差异有统计学意义(P<0.05);灵敏度(92.50%)高于CT诊断(81.25%);CT、MRI在诊断鼻咽癌的特异度方面差异无统计学意义(P>0.05);CT与MRI鼻咽部检查结果显示在海绵窦、颞下窝差异有统计学意义(P<0.05);颅底部鼻咽癌检查显示,CT鼻咽癌检出率31.67%低于MRI鼻咽癌检出率50.00%,差异有统计学意义(P<0.05)。结论:CT检查与MRI检查都可观察到鼻咽癌的侵入情况,但MRI检查对于鼻咽癌诊断的准确率和灵敏度高于CT检查。Objective To analyze the clinical value of CT and MRI for the diagnosis of nasopharyngeal carcinoma(NPC).Methods Ninety-eight cases of suspected nasopharyngeal cancer admitted to Wenshang County People's Hospital from January 2020 to January 2024 were selected as the objects of this study,and all patients were examined by CT and MRI,and the results of the pathological examination were used as the gold standard for diagnosis,so as to evaluate the diagnostic value of CT and MRI for nasopharyngeal cancer.Results Pathological examination revealed,Eighty patients were diagnosed with nasopharyngeal carcinoma,The CT examination indicated that 70 patients had nasopharyngeal carcinoma;The MRI examination suggested that 76 patients had nasopharyngeal carcinoma.The accuracy of MRI for NPC diagnosis(91.84%)was higher than CT diagnosis(79.59%)(P<0.05).Sensitive(92.50%)was higher than CT diagnosis(81.25%);CT and MRI in specificity of NPC was significant non-difference(P>0.05).CT and MRI showed significant difference in cavernous sinus and inferior temporal fossa(P<0.05).The examination of nasopharyngeal carcinoma at the base of the skull shows that,the detection rate of nasopharyngeal carcinoma on CT was 31.67%,lower than that on MRI,which was 50.00%(P<0.05).Conclusion However,NPC invasion can be observed in both CT and MRI examinations,but MRI examination is more accurate and sensitive than CT examination for NPC diagnosis.
