Example reconstructed SPECT and CT (with and without lesions) transverse slices at the level of sternum and spine lesions of the male patient study with artificial lesions. Red arrows show the lesion locations. VOI used to analyze the reconstructed SPECT studies had the same shape and position as the lesion seen on the CT image. AMAP-S and AMAP-R refer to reconstructions where lesion is absent in the CT and AMAP-S CT and AMAP-R CT to lesion-present cases. The color scale is set to SUV 15 for all SPECT images
