T1-weighted MRI and parametric images of BP, variability, and reliability (ICC) for an inferior (cerebellar) and superior (striatal) slice. Variability and ICC images were masked (i.e., shown in black) at BP > 0.3 and by segmented gray matter MRI image. Parametric images for BP, variability, and ICC were similar for 240- and 300-min data.
