Fig. 2From: Whole tumor kinetics analysis of 18F-fluoromisonidazole dynamic PET scans of non-small cell lung cancer patients, and correlations with perfusion CT blood flowa Two-, b three-, and c four-tissue compartment models used to analyze the dynamic PET data. Flow rates from one compartment to another are defined by rate-constants (k values), tracer concentrations and compartment volumes [12]. The fraction of the tumor volume occupied by blood is denoted in each model as νBBack to article page
