Diffusion tensor imaging of the corticospinal tract in patients with brain neoplasms.
PURPOSE To maximize the extent of tumor resection and minimize postoperative neurological deficits in patients with brain neoplasms, it is very important to evaluate the integrity of the corticospinal tract (CST) before surgery. We attempted to determine whether CST abnormality in these patients correlates with clinical motor weakness. METHODS We retrospectively evaluated 19 patients (16 men,...

متن کاملOptimal Factors of Diffusion Tensor Imaging Predicting Corticospinal Tract Injury in Patients with Brain Tumors
OBJECTIVE To identify the optimal factors in diffusion tensor imaging for predicting corticospinal tract (CST) injury caused by brain tumors. MATERIALS AND METHODS This prospective study included 33 patients with motor weakness and 64 patients with normal motor function. The movement of the CST, minimum distance between the CST and the tumor, and relative fractional anisotropy (rFA) of the CS...
متن کاملIdentification of the anterior corticospinal tract in the human brain using diffusion tensor imaging.
The corticospinal tract (CST) is generally classified into the crossed lateral CST and the uncrossed anterior CST. No diffusion tensor imaging study for identification of the anterior CST in the human brain has been conducted. Using diffusion tensor imaging, we attempted to identify the anterior CST and investigate the characteristics of the anterior CST in the normal human brain. We recruited ...
متن کاملCorticospinal Tract Change during Motor Recovery in Patients with Medulla Infarct: A Diffusion Tensor Imaging Study
Diffusion tensor imaging (DTI) and tractography (DTT) provide a powerful vehicle for investigating motor recovery mechanisms. However, little is known about these mechanisms in patients with medullary lesions. We used DTI and DTT to evaluate three patients presenting with motor deficits following unilateral medulla infarct. Patients were scanned three times during 1 month (within 7, 14, and 30 ...
