Abstract

Two cases of atlantoaxial (A-A) instability that showed different MRI findings between supine and upright positions are presented. The upright MRI represented the findings corresponding to their symptoms. In A-A lesions, conventional MR images taken in the supine position do not always explain the pathophysiological consequences. The MR images taken in the upright position disclose the actual spinal pathophysiology with gravitational effects.

摘要

本文报告了两例寰枢椎（A-A）不稳病例，其仰卧位和直立位的MRI表现不同。直立位MRI显示的结果与患者症状相符。在A-A病变中，仰卧位拍摄的传统MR图像并不总能解释其病理生理后果。直立位拍摄的MR图像可揭示重力作用下实际的脊柱病理生理情况。
