Quantitative Measurement of Corticospinal Tracts by MR Fiber Tractography: A Reproducibility Study
纤维束示踪成像技术的定量测量：可重复性研究
Conclusion The average FA of the corticospinal tracts of RRMS patients is significantly abnormal and this index may be suitable in evaluating the functional status of the cerebral type of RRMS patients.
结论RRMS患者皮质脊髓束的FA值存在明显异常，该指标可用作评价脑型RRMS患者的临床功能状态。
Results MR appearances of CPM were as followed:( 1) The location of CPM was in the center of the pons. Transverse pontine fibers were most severely affected with sparing of descending corticospinal tracts.
结果CPM的MRI特征表现为：（1）病变位于脑桥中央部位，主要累及桥横纤维的髓鞘，皮质脊髓束的轴索保持完好；
3D-DOCTOR software was used to make threshold segmentation and to reconstruct spinal cord, grey matter and bilateral corticospinal tracts ( CSTs) of rat.
利用3D-DOCTOR软件进行阈值分割并对大鼠脊髓、脊髓灰质、双侧皮质脊髓束结构进行三维重建，在PC机上对重建结构进行任意角度的观察，切割和测量。
