Choroid plexus signal is readily apparent on Arterial Spin Labeling images but its perfusion characteristics have not been systematically studied. Since the choroid plexus plays an important role in both cerebrospinal fluid production and composition, measuring its function may yield insights into cerebrospinal fluid physiology and disease. In this work, we report initial measurements of the choroid plexus blood flow with noninvasive arterial spin labeling methods using anatomically defined regional measurements.
