Synopsis

There are no reports on the use of TractSeg in patients with brain arteriovenous malformations (BAVMs). This study aimed to investigate the effect of the presence of BAVMs on TractSeg findings of the corticospinal tract (CST) and their clinical usefulness. In case of BAVMs through which the CST runs, the visualization was affected, but in most cases, tractography reconstruction was possible. In case of BAVMs through which the CST does not run, the same results as that of normal volunteers were obtained.
