Fig. 7From: Improved quantitation and reproducibility in multi-PET/CT lung studies by combining CT informationRegional variation in the K i measurements using combined-CT reconstructions for analysis. Comparison of the fibrotic and normal appearing tissue influx rate constants determined after the PET data were reconstructed with the combined-CT, using compartmental modelling (Ki2) and Patlak-Rutland analysis (K iP ) for all patients.
