Multiparametric FDG-PET/MRI of Hepatocellular Carcinoma: Initial Experience
(a) Correlation plots between SUVmax T/L (i.e., ratio between SUVmax values in HCC vs. liver) and DCE-MRI parameters transfer constant from Tofts model (Ktrans TM), extravascular extracellular fraction from Tofts model ( TM), and transfer constant from shutter-speed model (Ktrans SSM). Treatment-naive HCC lesions are shown as circles and treated HCC lesions are shown as triangles. (b) Correlation plots of SUVmean T/L (top) and SUVmax T/L with DCE-MRI parameters Ktrans TM, TM, and Ktrans SSM in treatment-naive HCC lesions only. The correlation coefficient and corresponding FDR-adjusted values are shown in the top right corner of each plot.
