扩散张量成像是无创性显示和分析白质纤维束的一项新技术,在缺血性中风的临床研究中正广泛地使用,它提供的信息能补充MRI技术的不足,经常能更早地显示病理改变,特别是扩散张量成像能显示白质纤维束的走行方向,用于检测大脑功能分区间神经联络的变化,还能追踪缺血性中风发展演变过程,评估缺血性损伤的严重程度和预测中风结果。
Diffusion tensor imaging is a novel technique for the noninvasive display and analysis of white matter fiber bundles and is widely used in clinical studies of ischemic stroke, providing information that can complement the inadequacies of MRI techniques and often show pathology earlier Changes, especially diffusion tensor imaging, can show the travel direction of white matter fiber bundles, to detect changes in neural connections between brain functional compartments, to track the evolution and progression of ischemic stroke, and to assess the severity and prognosis of ischemic injury Stroke results.
