The most commonly used technique for perfusion MRI is dynamic susceptibility, which involves generating maps of brain perfusion by monitoring the first pass of a rapid bolus injection of contrast through the cerebral vasculature. Susceptibility-related T2 effects create signal loss in capillary blood vessels and parenchyma perfused by contrast.
