Sarcoidosis is a complex multisystem inflammatory disease characterized by noncaseating granulomas and variable clinical manifestations, most commonly affecting the lungs, skin, heart, and nervous system. Imaging is central in its diagnosis, staging, and management, providing essential insights into organ involvement and disease activity. Pulmonary manifestations remain the hallmark, with modalities such as high-resolution chest computed tomography (CT) and chest radiography offering critical diagnostic clues. Imaging techniques, including Fluorodeoxyglucose Positron Emission Tomography (FDG-PET) and cardiac magnetic resonance imaging, are invaluable for identifying cardiac and systemic involvement, including cutaneous and musculoskeletal, while abdominal MRI and ultrasound help delineate hepatic and splenic manifestations. Neurosarcoidosis requires MRI for precise evaluation, supplemented by FDG-PET to guide biopsy and monitor treatment response. This chapter synthesizes the imaging features of sarcoidosis across organ systems, emphasizing practical approaches to diagnosis and management while identifying key areas for future research.
