The use of 67Ga scintigraphy in patients with sarcoidosis.

Sarcoidosis is a systemic disease of unknown aetiology characterised by the formation of noncaseating granulomas in various organs and tissues. The various imaging modalities that are useful in the investigation of lesions, staging and establishing indications for treatment include: conventional radiography, CT, MRI, and scintigraphy with ⁶⁷Ga, ²⁰¹Tl, 99mTc sestamibi, and somatostatin receptor scintigraphy (SRS) as well as ¹⁸F-FDG-PET/CT. This paper discusses the most commonly used technique of the scintigraphic, gallium (⁶⁷Ga) citrate) and its role in the evaluation and monitoring of patients with sarcoidosis.
