Parameters of the theoretical time-enhancement curves (TECs) for brain tissue.<br /> There were 653310 combinations of each perfusion parameter, although combinations of high flow (CBF > 120 ml∙(100 g) ^ (-1)∙min ^ (-1)) and low flow (CBF < 5 ml∙(100 g) ^ (-1)∙min ^ (-1)) parameters were excluded, which resulted in 540582 theoretical TECs for brain tissue.
