Uptake in nonosseous, nonurologic tissues is occasionally found in the performance of bone scintigraphy. Proper interpretation of these cases depends on identifying the involved organs and appreciating the significance of the uptake. Because of the rarity of these findings and a relative de-emphasis of planar imaging in radiologic imaging, current era trainees may exhibit difficulty in identifying organs on planar projections. The first section of this work consists of an image atlas depicting uptake...
