We present a semiautomatic technique to perform regional quantification of brain Cerebral Blood Volume (CBV) maps obtained by MR Perfusion Weighted Images, using structural MRI images. A Talairach grid system is built on the brain anatomical MRI, and a co-registered CVB map is superimposed on the grid for a regional assessment of brain CVB.
