【摘要】：目的分析迷路炎的CT和MRI影像表现,同时进行CT与MRI图像融合,探讨其对迷路炎的应用价值。方法回顾性分析诊断为迷路炎的23例(30耳)的影像学资料,22例(29耳)行CT检查,9例(14耳)行MRI检查,对其中6例(10耳)同时有CT和MRI检查者进行CT与MR图像融合。结果CT上1耳未见异常,5耳同时表现为骨迷路狭窄/闭塞和骨质破坏,7耳仅有骨质破坏,5耳仅表现为骨质密度增高,11耳仅表现为骨迷路狭窄/闭塞。MRI上2耳表现为膜迷路信号减低、消失,伴有管腔局部狭窄/中断;8耳仅表现为膜迷路信号减低、消失;4耳仅表现为膜迷路的管腔局部狭窄/中断。CT-MRI融合图像中,CT反相MRI不反相有利于骨迷路和膜迷路病变的显示,CT不反相MRI反相有利于骨迷路病变的显示。结论CT与MRI相结合可以提供更全面的影像学信息,有利于迷路炎的影像诊断。
[Abstract]:Objective to analyze CT and MRI findings of labyrinthitis and to evaluate the value of CT and MRI fusion in labyrinthitis. Methods the imaging data of 23 cases (30 ears) with labyrinthitis were retrospectively analyzed. 22 cases (29 ears) were diagnosed as labyrinthitis. Ct examination was performed in 9 cases (14 ears) and MRI was performed in 9 cases (10 ears). Ct and Mr images were fused in 6 cases (10 ears) with both CT and MRI examinations. Results on CT, there was no abnormality in 1 ear. 5 ears showed bony labyrinthine stenosis / occlusion and bony destruction in 7 ears and only bone destruction in 5 ears. 11 ears showed bone density increase and 11 ears showed bony labyrinthine stenosis / occlusion. For the loss of membranous labyrinth signal, In 8 ears with local stenosis / interruption of lumen, the signal intensity of membranous labyrinth was decreased. In the fusion image of CT, CT inverse MRI is beneficial to the display of labyrinth and membranous labyrinth lesions. The CT without inverse MRI is beneficial to the display of bony labyrinthine lesions. Conclusion CT combined with MRI can provide more comprehensive imaging information and be helpful to the diagnosis of labyrinthitis.
