多层螺旋CT多平面重建在鼻腔内翻乳头状瘤诊断中的价值

The Value of Multiplanar Reconstruction with Multi-slice Spiral CT in the Diagnosis of Nasal and Paranasal Inverted Papilloma

目的:探讨多层螺旋CT多平面重建技术在诊断鼻腔及副鼻窦内翻乳头状瘤的临床价值。方法:回顾性分析26位病理证实内翻乳头状瘤患者的28次CT检查图像,通过对原始图像多平面容积重组图像后处理,分析其影像学特征。结果:内翻乳头状瘤特点是好发于单侧鼻腔,累及中鼻道及鼻外侧壁,分叶状形态是另一典型特征。结论:多层螺旋CT结合多平面重建技术能准确反映内翻乳头状瘤的形态学特征,对其诊断与鉴别诊断有较高的临床价值。

Objective:To explore the diagnostic value of multiplanar reconstruction (MPR) with multi-slice spiral CT on nasal and paranasal inverted papilloma.Materials and Methods:Findings of 28 CT examinations in 26 patients with histologically proven inverted papilloma were retrospectively analyzed,The CT images were managed multi planar volume recombination and analysis its imaging features. Results:Unilateral tumor localization involving the lateral nasal wall and the middle meatus was the feature that best correlated with the finding of primary inverted papilloma. A lobulated surface pattern was another typical sign.Conclusion: Multi-slice CT in combination with MPR can Reflect the morphological features of inverted papilloma,have a high clinical value of diagnosis and differential diagnosis.
