MR DTI作为目前唯一能显示水分子运动方向和强度的成像技术,可以动态反应中枢神经系统白质的超微结构及相应病理生理改变,为研究脊髓损伤提供了新的方法.近年来脊髓DTI已应用于临床.本文对脊髓DTI技术的应用、发展趋势进行综述.%At present, MR DTI, as the only imaging method to detect the direction and intensity of hydrone motion, is capable of dynamically reflecting ultrastructures and relative pathophysiologic changes of white matter in central nervous system, providing a new access for research of spinal cord injury (SCI). For the past few years, spinal cord DTI has been applied clinically. The development and application of spinal cord DTI were reviewed in this article.
