Scatter plot of pixel Ktrans values obtained from single-image slice pharmacokinetic modeling analyses of a patient's DCE-MRI data. The Ktransextracted with the average AIF (Avg-AIF) approach are plotted against those extracted with the individually measured AIF (Ind-AIF) approach. Both identity line and regression line are shown. The slope of the linear regression is 1.35.
