A common misconception is that indicator dilution theory cannot be used to derive perfusion parameters such as cerebral blood flow (CBF) and cerebral blood volume (CBV) if tracer recirculation is present in dynamic susceptibility contrast MR perfusion data. Here, we show that it is unnecessary to remove tracer recirculation from DSC-MR data in order to derive perfusion parameters.
