Sarcoidosis is a systemic granulomatous disease that can affect multiple organ systems, leading to a wide range of radiologic manifestations. High-resolution CT (HRCT) is particularly useful in evaluating pulmonary involvement, revealing findings such as perilymphatic nodules, bronchovascular bundle thickening, and fibrosis. MRI is valuable in assessing cardiac and central nervous system involvement, providing detailed tissue characterization. PET/CT with fluorodeoxyglucose (FDG) is effective in detecting active inflammatory sites and assessing the extent of systemic involvement. These imaging modalities are essential for accurate diagnosis, assessing disease activity, guiding biopsy, and monitoring treatment response. A comprehensive understanding of the imaging features of sarcoidosis across different modalities and organ systems is crucial for effective patient management.
