Imaging features of sarcoidosis on MDCT, FDG PET, and PET/CT.
OBJECTIVE
The objectives of this article are to discuss the epidemiology and natural history of sarcoidosis; to review the classic imaging features of sarcoidosis on radiography, CT, and 67Ga nuclear medicine scans; and to present clinical examples of sarcoidosis as seen on PET and PET/CT in the chest, abdomen and pelvis, and bones.


CONCLUSIONS
The imaging features of sarcoidosis are diverse and can be seen on a variety of imaging techniques. It is important for radiologists and nuclear medicine physicians to recognize the common imaging features and patterns of sarcoidosis in order to raise the possibility in the appropriate clinical setting.
