Fiber tractography based on diffuse tensor imaging (DTI) can reveal three-dimensional white matter connectivity of the human brain. Tractography is a non-invasive method of visualizing cerebral white matter structures in vivo, including neural pathways surrounding the ischemic area. DTI may be useful for elucidating alterations in brain connectivity resulting from neuroplasticity after stroke. We present a case of a male patient who developed significant mixed aphasia following ischemic stroke. The patient had been treated by mechanical thrombectomy followed by an early rehabilitation, in conjunction with transcranial direct current stimulation (tDCS). DTI was used to examine the arcuate fasciculus and uncinate fasciculus upon admission and again at three months post-stroke. Results showed an improvement in the patient's symptoms of aphasia, which was associated with changes in the volume and numbers of tracts in the uncinate fasciculus and the arcuate fasciculus.
基于弥散张量成像（DTI）的纤维束成像能够揭示人类大脑的三维白质连接。纤维束成像是一种在体内可视化脑白质结构的非侵入性方法，包括缺血区域周围的神经通路。DTI可能有助于阐明中风后神经可塑性导致的脑连接改变。我们报告一例男性患者，其在缺血性中风后出现严重的混合性失语。该患者接受了机械取栓治疗，随后进行早期康复，并结合经颅直流电刺激（tDCS）。在入院时以及中风后三个月再次使用DTI检查弓形束和钩束。结果显示患者失语症状有所改善，这与钩束和弓形束的束体积和数量变化有关。
