Figure 5:

19 year-old female with history of right adrenal gland adrenocorticocarcinoma with several bone metastases. First PET/CT was obtained after chemotherapy. A very subtle area of lucency surrounded by minimal sclerosis (arrow) correlates with area of photopenia on the correlating PET images. These findings probably represent response to treatment. The high spatial resolution and improved signal-to-noise ratio allow for detection of small photopenic region which can be often useful for therapy response.
