The identification of the extent of neural damage in patients with acute or chronic spinal cord injury is imperative for the accurate prediction of neurological recovery. The changes in signal intensity shown on routine MRI sequences are of limited value for predicting functional outcome. Diffusion tensor imaging (DTI) is a novel radiological imaging technique which has the potential to identify intact nerve fibre tracts, and has been used to image the brain for a variety of conditions. DTI imaging of the spinal cord is currently only a research tool, but preliminary studies have shown that it holds considerable promise in predicting the severity of spinal cord injury. This paper briefly reviews our current knowledge of this technique.
确定急性或慢性脊髓损伤患者神经损伤的程度对于准确预测神经功能恢复至关重要。常规MRI序列上显示的信号强度变化对预测功能结局的价值有限。扩散张量成像（DTI）是一种新型放射成像技术，它有潜力识别完整的神经纤维束，并已用于多种情况下的脑部成像。脊髓的DTI成像目前仅是一种研究工具，但初步研究表明，它在预测脊髓损伤的严重程度方面很有前景。本文简要回顾了我们目前对该技术的认识。
