摘    要:目的:探讨成人中耳,内耳解剖结构CT三维重建技术,方法:采用螺旋CT薄层扫描(层厚1mm或2mm),小视野(FOV=5cm),密集重建技术(间隔0.2mm或0.5mm),对75例成人中耳,内耳进行三维成像,包括多平面重组(MPR),最大密度投影(MaxIP),表面成像(SSD)和仿真内镜成像(CTVE)。结果:中耳鼓室,听骨链,内耳及内耳道均获得满意三维图像。结论:螺旋CT三维重建技术的应用能够真实准确观察成人中耳,内耳立体结构。

关 键 词:中耳 内耳 三维重建 解剖结构 螺旋CT

Abstract:Objective:To explore the application of 3D spiral CT of adult middle and inner ear.Methods:3D imaging spiral CT of adult middle and inner ear,including multiplanar reconstructions(MPR), maximum intensity projection(MaxIP),surface shaded display(SSD) and CT virtual endoscopy (CTVE),was performed with 1mm or 2mm slice thickness,5cm field of view and 0.2mm or 0.5mm reconstruction interval in 75 subjects.Results:Satisfactory 3D images of tympanic cavity in middle ear,the auditory ossicular chain,inner ear,internal auditory meatus were obtained.Conclusion:3D spiral CT could accurately demonstrate the three dimensional structure of adult middle and inner ear.
Keywords:Middle ear Inner ear Tomography  X ray computed Three dimensional reconstruction
