Volume Effects

Partial volume effects are present in all medical imaging methods, and they play a specific role in arterial spin labeling (ASL) MRI measurements of perfusion. This chapter demonstrates how differences in the perfusion properties of gray matter, white matter, and cerebrospinal fluid give rise to the distinctive visual appearance of cerebral perfusion images. The implications of this for quantification of perfusion in gray matter are discussed and solutions to correct for partial volume effects presented.
