Fig. 6
Correlation between fully quantitative compartmental modeling using K 1 (left plots) or macroinflux parameter K i (right plots) and simplified methods SUV (row A) and Patlak (row B) across all tissues. K i showed better correlation with the simplified methods than K 1. However, the good correlations observed between K i and both SUV and Patlak were mainly attributed to the relatively large intertissue range of values used for the regression fit. Points corresponding to tumor activity are represented by triangles, those from healthy prostate tissue are diamonds, and muscle are squares
