Baseline MRI was recommended in acute spinal cord injury for clinical decision making and outcome prediction. The study presented a new quantitative method for evaluating the spinal cord severity to grade the retained fiber tracks by zoom DTI in pre-operation. For patients with ASIA A, no ASIA grade got promoted in FTClass A1 with completely fibers interruption and 3 out of 6 patients converted to C within 6-month follow-up in FTclass A2 with partially retention. The retained spinal cord fibers were critical for postoperative functional recovery. Multimodal MRI, especially accurate DTI provide potential quantitative predictive indicators for prognosis.
