Evaluation of the metabotropic glutamate receptor subtype 5 using PET and 11C-ABP688: assessment of methods


Treyer, V; Streffer, J; Wyss, M T; Bettio, A; Ametamey, S M; Fischer, U; Schmidt, M; Gasparini, F; Hock, C; Buck, A (2007). Evaluation of the metabotropic glutamate receptor subtype 5 using PET and 11C-ABP688: assessment of methods. Journal of Nuclear Medicine, 48(7):1207-1215.

Abstract

(11)C-ABP688 displays favorable kinetics for assessing mGlu(5) receptors. For tracer kinetic modeling, 2-tissue-compartment models are clearly superior to models with only 1 tissue compartment. In comparison to the compartmental models, the Logan method is equally useful if only DV(tot) values are required and fast pixelwise parametric maps are desired. The lack of regions devoid of receptors limits the use of reference region methods that do not require arterial blood sampling. Another advantage of the tracer is the fast kinetics that allow for relatively short acquisitions.
