Abstract
To improve definition of the spinal cord when it lies anteriorly, turning the patient from the lateral decubitus to the supine position and obtaining a horizontal-beam lateral radiograph of the cervical spine is recommended. Supine positioning permits improved visualization of the anterior subarachnoid space and evaluation of extradural lesions encroaching upon it, as well as abnormal fixation of the cord.
摘要
为了在脊髓位于前方时提高其清晰度，建议将患者从侧卧位转为仰卧位，并获取颈椎的水平侧位X线片。仰卧位可更好地显示蛛网膜下腔前部，并评估侵犯该部位的硬膜外病变以及脊髓的异常固定情况。
