Orientation Prior and Consistent Model Selection Increase Sensitivity of Tract-Based Spatial Statistics in Crossing-Fiber Regions

The goal of this paper is to increase the statistical power of crossing-fiber statistics in voxelwise analyses of diffusion-weighted magnetic resonance imaging (DW-MRI) data. In the proposed framework, a fiber orientation atlas and a model complexity atlas were used to fit the ball-and-sticks model to diffusion-weighted images of subjects in...

Longitudinal analysis of diffusion-weighted MRI with a ball-and-sticks model

Purpose: To increase the sensitivity in longitudinal analysis of DW-MRI data with the ball-and-sticks model.
