Influence of blood/tissue differences in contrast agent relaxivity on tracer-based MR perfusion measurements
Perfusion assessment by monitoring the transport of a tracer bolus depends critically on conversion of signal intensity into tracer concentration. Two main assumptions are generally applied for this conversio...
