弥散张量成像(diffusion tensor imaging,DTI)技术是目前唯一可以在活体显示脑白质纤维束的无创性检查方法,现已成为临床追踪颅内白质纤维束走形最常用的工具之一。DTI技术在颅内肿瘤的鉴别诊断、治疗方案制定与疗效评价以及纤维束损伤程度的判断等方面发挥了重要的参考作用,与其他功能磁共振成像联合应用具有更高的临床应用价值和发展前景。 Diffusion tensor imaging (DTI) is currently the only noninvasive method that can detect white matter in vivo. It has become one of the most commonly used tools to trace the trabecular white matter trabeculae. DTI technology plays an important reference role in the differential diagnosis of intracranial tumors, the development and evaluation of therapeutic regimens, and the judgment of the extent of fiber bundle damage. Combined with other functional magnetic resonance imaging, DTI has higher clinical value and development prospects .
