Comparison of the VoI segmentation of the right kidney of patient 7 based on the two different methodologies. Left: segmentation performed by expert 2. Right: segmentation when using the AI. The red contours illustrate segmentation on CT while the yellow contours show activity segmentation. Underestimated activity areas by the AI algorithm are pointed by a yellow arrow and overestimated activity areas by a white arrow
