Reduction of arterial partial volume effects for improved absolute quantification of DSC-MRI perfusion estimates: Comparison between tail scaling and prebolus administration.

Summary, in English

To evaluate and mutually compare the tail-scaling approach and the prebolus administration concept for reduction of arterial partial volume effects (PVEs), because reproducible absolute quantification of cerebral blood flow (CBF) by dynamic susceptibility contrast magnetic resonance imaging (MRI) is often hampered by PVEs in the arterial input function (AIF) registration.
