AARD

Objective To evaluate 3 D CT reconstruction in diagnosing atlanto axial rotatory displacement ( AARD ) in children.

目的　探讨三维CT成像(3DCT)对小儿寰枢椎旋转性移位 ( atlantoaxialrotatorydisplacement,AARD ) 的诊断价值.

Project Aardvark Blog In2005, a team of four summer interns built the first version of Fog Creek Copilot from start to finish.

2005年的Aardvark博客项目，四个暑期实习生自始至终开发了第一版的Fog Creek Copilot。

Results According to 36 cases with AARD, the fixed angle of atlantoaxial, altas dislocation, fracture, shape of spinal canal and the lesions around could be clearly found on CT image.

结果36例寰枢关节旋转脱位CT均可清晰显示寰枢椎间固定角度及寰椎移位、寰枢椎骨折、骨性椎管的形态及周围病变等。
