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 … Webb"The reference tissue model allows for quantification of receptor kinetics without measuring the arterial input function, thus avoiding arterial cannulation and time …

Webb31 juli 2024 · Performance of both the full reference tissue model (FRTM) [23, 24] and the simplified reference tissue model (SRTM) was investigated. The advantage of reference tissue input models is that no arterial input function is needed. Instead, a reference region is used as indirect input function, in this case, the contralateral reference region. WebbKinetic modelling. The MAGIA system currently has implementations for the follwing PET models which can all be used depending on the type of PET data that are available.
