【摘要】 目的:探讨青少年上肢远端肌萎缩症在不同检查方法下的MRI表现特点。方法:3例经临床证实的青少年上肢远端肌萎缩症患者采用PHILIPS3.0T磁共振机,先取常规仰卧位下颈椎MRI检查,再行屈颈位下MRI检查,探讨MRI检查方法及表现。结果:常规仰卧位显示脊髓萎缩和脊髓背侧硬膜外静脉丛扩张;屈颈位可见下段颈髓局限受压变细及硬脊膜后壁向前推移。结论:青少年上肢远端肌萎缩症在不同检查体位下有特征性MRI表现。更多还原

【Abstract】 [Objective] To investigate MRI features of juvenile muscular atrophy of distal upper extremity with different inspection methods.[Method] We analyzed the MRI results of three confirmed cases of juvenile muscular atrophy of distal upper extremity to explore the methods and performance of the MRI examination.[Result] Spinal cord atrophy and spinal cord dorsal epidural venous plexus expansion could be detected with conventional supine position.Neck flexion position can detect attenuation of the lower segments of the cervical spinal cord under pressure and spinal dura mater was onward.[Conclusion] There are different features of MRI results with different position in patients of juvenile muscular atrophy of distal upper extremity.更多还原
