CT与MRI对鼻腔鼻窦内翻性乳头状瘤的诊断价值

Diagnostic value of CT and MRI in inverted papilloma of nasal cavity and paranasal sinus

目的探讨CT及核磁共振检查对鼻腔鼻窦内翻性乳头状瘤的诊断价值.方法对100例鼻腔鼻窦内翻性乳头状瘤患者接受CT及核磁共振检查的临床资料进行回顾性分析,比较两种检查方法诊断的准确性、特异度、灵敏度,并对检查结果的影响因素进行Logistic回归分析.结果本组患者CT阳性预测值低于MRI诊断,差异有统计学意义(P<0.01),诊断灵敏度、特异度、阴性预测值两者比较差异无统计学意义(P>0.05).病变鼻腔数为双侧、疾病情况为复发、TNM分期为T3+T4的患者鼻腔鼻窦内翻性乳头状瘤检出率较高(P<0.05或0.01);患者的病变鼻腔数和疾病情况是影响其检查结果准确性的独立危险因素(P<0.05或0.01).结论核磁共振对鼻腔鼻窦内翻性乳头状瘤的诊断准确性高于CT检查,且受病变鼻腔数和疾病情况的影响.

Objective To observe the diagnostic value of CT and MRI in inverted papilloma of nasal cavity and paranasal sinus.Methods Retrospective analysis of clinical data of 100 patients with nasal cavity and paranasal sinus undergoing CT and MRI was performed.The accuracy,specificity and sensitivity of the two methods were compared,and the logistic regression analysis was performed on the influencing factorsof the test results.Results The detection rate of nasal sinus inverted papilloma was higher in patients with bilateral lesions,bilateral recurrence,and TNM stage T3+T4(P<0.05 or 0.01).The number of lesions and disease situation were independent risk factors affecting the accuracy of the test results(P<0.05 or 0.01).Conclusion The diagnostic accuracy of NMR in the inverted papilloma of the nasal cavity and sinus is higher than that of the CT examination,and it is affected by the number of lesions and the disease situation.
