MPR在眼眶爆裂骨折诊断中的应用
Chinese Imaging Journal of Integrated Traditional and Western Medicine(2013)
Abstract
目的:探讨16层CT MPR对眼眶爆裂骨折的诊断价值。方法:回顾性分析46例眼眶爆裂骨折的16层CT的横断位、MPR及3D图像。结果:MPR能准确显示骨折,直接显示出骨折线11例,内直肌增粗32例,眼肌及眶内脂肪疝入副鼻窦者26例,内直肌及眶内侧壁之间脂肪间隙变窄或消失者25例,眶内及眼睑皮下积气20例,副鼻窦积液或塌陷者35例。46例均见眼眶周围软组织肿胀。眶内侧壁骨折以横断面显示最佳,眶下壁骨折以冠状面及矢状面显示最佳,混合性骨折以冠状面显示最佳。结论:16层CT容积扫描的MPR能全面而准确地诊断眼眶爆裂骨折,对临床治疗及预后评估有重要价值。
