Abstract
ObjectiveThe difference in the widest distance between corticospinal tracts (CST) on diffusion tensor tractography (DTT) in stroke patients with hydrocephalus was investigated retrospectively.MethodsDistances were measured on an axial slice of the corona radiata, which provided the widest distance between CSTs. Two distances were measured, the absolute distance – the distance between the most medial point of the CSTs and the relative distance – calculated as a percentage of the absolute distance.ResultsThe absolute distances of CSTs were 55.34 mm for the patient group and 46.75 mm for the control group. The relative distances of the CSTs were 44.12% and 35.96% for the patient group and the control group. Significant differences in the absolute and relative distances of CSTs were observed between the patient and the control group.ConclusionThese results suggest that the absolute and relative distances between CSTs might be used to diagnose hydrocephalus in stroke patients.
