Predictability of motor outcome according to the time of diffusion tensor imaging in patients with cerebral infarct.

Introduction: Predictability of diffusion tensor imaging tractography (DTT) for motor outcome can differ according to the time of DTT. We attempted to compare the predictability for motor outcome according to the time of diffusion tensor imaging (DTI) by analyzing the corticospinal tract (CST) integrity on DTT in patients with corona radiata (CR) infarct.

Methods: Seventy-one consecutive hemiparetic patients with CR infarct were recruited.
