From: CT-perfusion measurements in pancreatic carcinoma with different kinetic models: Is there a chance for tumour grading based on functional parameters?

Fig. 3

Plotted data of thee corresponding functional parameters calculated with both methods. Red line is the linear regression function for each functional parameter with indicated ICC and Pearsons r. a Linear regression analysis for BFMS vs. BFD showed a strong correlation and a good linear fit with a resulting slope of 1.5. (b and c) Despite significant differences between Patlak- and deconvolution models (BVP vs. BVD and k-transP vs. k-transP), moderate to good correlation between the functional perfusion-based parameters with regard to ICC and Pearson’s linear correlation coefficient were found. Abbreviations: BFD = blood flow calculated with deconvolution; BFMS = blood flow calculated with maximum slope; BVD = blood volume calculated with deconvolution; BVP = blood volume calculated with Patlak; k-trans = permeability surface area product, or k-trans; k-trans; D = k-trans calculated with deconvolution; k-transP = k-trans calculated with Patlak
