4 case question available
- notice the classic location for brown fat activation, including intensity and distribution
- correlate FDG uptake with the CT findings, brown fat activation leads to uptake solely in areas of fat on CT.
- use caution when interpreting PET-CT with brown fat activation, consider having the patient return with brown fat activation precautions
