## Abstract Diffusion tensor magnetic resonance imaging (DTβMRI) has previously been used to investigate white matter tracts in schizophrenia, with inconsistent results. The aim of the study was to use a novel method for tractβspecific measurements of frontoβtemporal fasciculi in earlyβonset schizo

## Abstract A theoretical framework is presented for understanding the effects of noise on estimates of the eigenvalues and eigenvectors of the diffusion tensor at moderate to high signalβtoβnoise ratios. Image noise produces a random perturbation of the diffusion tensor. Power series solutions to
The effect of susceptibility differences between fluid and fibers on the properties of DTI fiber phantoms was investigated. Thereto, machine-made, easily producible and inexpensive DTI fiber phantoms were constructed by winding polyamide fibers of 15 microm diameter around a circular acrylic glass s
