A computationally efficient algorithm for determining regional cerebral blood flow in heterogeneous tissues by positron emission tomography.

Inclusion of brain tissues with different rates of blood flow and metabolism within a voxel or region of interest is an unavoidable problem with positron emission tomography due to its limited spatial resolution. Because regional cerebral blood flow (rCBF) is higher in gray matter than in white matt...
