Skeletal sarcoidosis is thought to occur in approximately 1–13% of patients and generally involves the peripheral skeleton. However, on imaging, some lesions may be indistinguishable from metastatic disease. PET/MR imaging can be used to detect lesions in sarcoidosis as they show intense FDG uptake. Characteristic MRI features and sarcoidosis distribution patterns, combined with simultaneous whole-body FDG PET acquisition, allow for excellent lesion detection, differentiation from malignancy, and assessment of disease activity.
