Using structural magnetic resonance imaging in a clinical scanner at 3.0 Tesla, we describe results showing that following twelve weeks on a diet of 2% cholesterol, rabbits experience a significant increase in the volume of the third ventricle compared to rabbits on a diet of 0% cholesterol. Using time-of-flight magnetic resonance angiography, we find cholesterol-fed rabbits also experience a decrease in the diameter of a number of cerebral blood vessels including the basilar, posterior communicating, and internal carotid arteries. Taken together, these data confirm that, despite the inability of dietary cholesterol to cross the blood brain barrier, it does significantly enlarge ventricular volume and decrease cerebrovascular diameter in the rabbit – effects that are also seen in patients with Alzheimer’s Disease.
