We hypothesized that the cerebral vasculopathy of Fabry disease is associated with abnormal cerebrovascular responses, and furthermore, that these would normalize with repeated intra-vascular infusion of α-galactosidase A [ 5 6 ] . We compared the functional cerebrovascular responses in Fabry disease to those in age and sex matched controls using both visual stimulation and acetazolamide challenge by [ 15O]H 2 O and positron emission tomography (PET) to measure rCBF.
Another report found changes on positron emission tomography scanning following two weeks of a comprehensive memory program that included memory training, special diet, physical exercise, and stress reduction [13].
First, in a mouse with human melanoma they used highly sensitive positron emission tomography (PET) scanning to show not only that the level of uptake of integrin was specific for the tumor, but also that the uptake was in direct proportion to the amount of avß3 expressed, thus potentially allowing quantification of receptor expression; however, larger tumors showed a poorer correlation, possibly because of the presence of necrotic areas that do not express the integrin.
With the advent of other noninvasive brain imaging techniques like positron emission tomography (PET) and functional magnetic resonance imaging (fMRI), it became possible to visualize brain activity of stutterers and compare these patterns to fluent controls.
In the late 1980s, neuroimaging experiments made possible the examination of activity in localized brain areas, first through the use of injected radionuclides detected by positron emission tomography (PET) [12] and later through the use of an externally imposed magnetic field in functional magnetic resonance imaging (fMRI) [13].
