Magnetization transfer (MT), susceptibility weighted
(SW) and diffusion tensor (DT) MR imaging are commonly
used techniques to study white matter damage in
neurodegenerative diseases. Using these methods, we
investigated the effects of cranial irradiation on white
matter pathology in the mouse. Differences were
detectable in many white matter structures using MT and
SW, but not DT MRI. We hypothesize that dymelination
plays a larger role in irradiation induced damage than
axonal changes. In the future we will study the effect
of myelin protection in this irradiation model, and see
how this affects the imaging outcomes.
