Segmented left kidney along axial, sagittal and coronal axis using the AI . The segmentation boundaries are highlighted with red contour on a contrast-enhanced CT on the left-hand side and on a low-dose CT on the right-hand side. The red rectangle corresponds to the bounding box used in kidney detection by the algorithm and the yellow contour is the 3 mm expanded region for activity retrieval from the SPECT images based on the CT-segmentation
