Flat detector derived parenchymal blood volume maps to estimate cerebral blood volume

Newer flat panel angiographic detector (FD) systems have the capability to generate parenchymal blood volume (PBV) maps. The ability to generate these maps in the angiographic suite has the potential to markedly expedite the triage and treatment of patients with acute ischemic stroke.

David Fiorella, Department of Neurological Surgery, Stony Brook University Medical Center, NY, and colleagues, have compared FP-PBV maps with cerebral blood volume (CBV) maps derived using standard dynamic CT perfusion (CTP) in a population of patients with stroke.

Rob Tarr asks him what they found.
