Simplified reference tissue model
Webb1 feb. 2011 · In both 3-tissue, 6-parameter, and 2-tissue, 4-parameter, models, the term K 1 represents transport across the blood–brain barrier, which is proportional to flow and tracer extraction. In simplified models that use a reference tissue in place of an arterial input function (simplified reference tissue model), the term R 1 represents the ratio of K … Webb23 juni 2024 · From the dynamic PIB PET scan, three rCBF images were generated, namely R 1 by pharmacokinetic modelling of the dynamic scan (using Simplified Reference Tissue Model 2 (SRTM2) and the grey matter of the cerebellum as the reference tissue), and 2 SUVR images by taking the time-weighted average of the initial frame intervals, i.e. …
