Modelling the impact of injection time on the bolus shapes in PET-MRI AIF Conversion

Published: 29 July 2014
With the introduction of combined PET/MRI systems, AIF conversion can be made under certain circumstances (see ). We propose a model that allows modification of the injection parameters in the AIF fit to account for differences caused by different injection durations .
This enables conversion of the early part of the AIFs from one modality to another even if different injection protocols are used.
