Fig. 4From: Kinfitr — an open-source tool for reproducible PET modelling: validation and evaluation of test-retest reliabilityMicroparameter comparison for the two-tissue compartment model (2TCM). The relationship between the values of individual rate constants calculated by either kinfitr or PMOD. All results were derived from the thalamus region. The diagonal line represents the line of identity. Each colour corresponds to a different subject, and the dotted lines connect both measurements from the same subjectBack to article page
