Fig. 1 Renal PET static images using H215O. Each image represents a transversal slice in which high activity corresponds to the cortex (orange arrow on image 2) and higher activity to the aorta (red arrow on image 2). Orientation: Ant = up, Right = left. The upper left image represents the subdiaphragm slice, the lower right image, the inferior slice. Color scale shown on left side of the image.

Fig. 2 Examples of aortic (dashed line) and tissue (solid lines) PET TACs from one patient. Input function (aortic PET TAC) represents the evolution in time of the mean of activity measured in the aortic ROI. Tissue function (kidney PET TACs, baseline [K bl], and periods 1 [K P1], 2 [K P2], 3 [K P3], and 4 [K P4]) represents the evolution in time of the mean of activity measured in the two kidneys ROI.
