目的 探讨CT及MRI在鼻腔鼻窦内 翻性乳头状瘤的临床诊断中的应用价值。 方法 回顾性分析我科2012年6月至2015 年11月期间行手术病理确诊鼻腔鼻窦内 翻性乳头状瘤患者100例，术前均有CT及 MRI检查，比较分析CT及MRI与病理诊断 (黄金标准)的符合率，并分析CT与MRI的 影像诊断特点。结果 病检起源部位检出 率100%明显高于CT的85%，病检分期检出 率100%显著高于CT的83%，比较差异明显 (P<0.05)，病检恶性检出率100%与CT75% 比较无明显差异(P>0.05)；病检恶性检出 率100%显著高于MRI的25%，比较差异显著 (P<0.05)，病检起源部位检出率100%与 MRI的97%比较无差异，病检分期检出率 100%与MRI的94%比较差异不大(P>0.05)； CT恶性检出率75%显著高于MRI的25%，CT 起源部位检出率85%显著低于MRI的97%， CT分期检出率83%显著低于MRI的94%，比 较有明显差异(P<0.05)。结论 CT联合MRI 检查可以全面显示鼻腔鼻窦内翻性乳头状 瘤的范围及其与周围软组织的界线，有助 于术前肿瘤临床分期以及肿瘤起源的准确 评估，从而更有利于实现早期诊断、早期 治疗。

Objective The value of the clinical diagnosis of by CT and MRI detected in nasal inverted papilloma. Methods A retrospective analysis of our hospital from June 2012 to November 2015 period pathologically confirmed nasal cavity and paranasal sinuses inverted papilloma 100 cases of tumor patients, preoperative CT and MRI were compared with analysis of CT and MRI pathological diagnosis (gold standard) compliance rates, and analyze the characteristics of imaging diagnosis of CT and MRI. Results The pathological examination site of origin 100% detection rate significantly higher than the 85% CT and pathologic examination stage detection rate of 100% was significantly higher than the 83% CT, more significant differences (P<0.05), the detection rate of malignant disease detection CT75% 100% and no significant difference (P>0.05), detection of malignant disease detection rate of 100% was significantly higher than 25% MRI, the difference was significant (P<0.05), pathological examination site of origin and the detection rate of 100% MRI of 97% was no difference in disease detection stage 100% detection rate of 94% compared with MRI little difference (P>0.05). CT malignancy detection rate of 75% was significantly higher than the 25% MRI, CT origin site inspection the rate of 85% was significantly lower than that of MRI 97%, CT staging detection rate of 83% was significantly lower than 94% MRI, and there were significant differences (P<0.05). Conclusion CT combined with MRI, can show full of nasal inverted papilloma scope and boundaries of the surrounding soft tissue, helps preoperative clinical stage and accurate assessment of tumor origin, and thus more conducive to early diagnosis, early treatment.
