Outline of Final Research Achievements

Q-Space imaging is a novel magnetic resonance technique that enables the assessment of ultrastructural changes of white matter. We hypothesized that this technique would facilitate the assessment of vascular dementia, such as cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL).
Six CADASIL patients were studied. Q-Space imaging was performed using a single shot, echo-planar imaging technique. Both q-space imaging and ADC maps depicted progressive neuronal damage. Early neuronal damage was especially well depicted using q-space imaging, with preferential involvement of the frontal lobes and central gray matters. Visual assessment of images revealed a trend for occipital lobe sparing, especially on q-space imaging. Q-Space imaging demonstrated early neuronal damage in CADASIL. Since this method appears to be sensitive to early neuronal damage, it could conceivably aid in evaluating vascular dementia.
