Diagnostic yield of a novel tracer 68Ga-citrate in sarcoidosis patients.

68Ga-citrate PET/CT was conclusive for activity assessment in sarcoidosis for diagnosis, activity assessment, and identification of extrapulmonary organ involvement. As an innovative novel tracer, 68Ga-citrate identified disease activity, extrapulmonary organ involvement, biopsy sites, and coexistent malignancy due to its chemical properties with a higher statistical diagnostic yield compared to conventional laboratory findings and the PET/CT imaging manifestations in sarcoidosis.
