  Beyond the Chest X-ray: How Nuclear Imaging Reveals the Hidden Burden of Sarcoidosis Gallium Scintigraphy, FDG PET/CT, and the Future of Precision Imaging in Systemic Granulomatous Disease Category: Nuclear Medicine | Molecular Imaging | Thoracic Radiology | PET/CT | Inflammatory Disease Keywords: Sarcoidosis, FDG PET/CT, Gallium Scan, Panda Sign, Lambda Sign, Nuclear Medicine, Granulomatous Disease, Molecular Imaging, Chest CT, Whole-Body Imaging Executive Summary Sarcoidosis is one of the most fascinating and challenging multisystem inflammatory diseases encountered in modern medicine. Although pulmonary involvement remains the hallmark of the disease, sarcoidosis is fundamentally a systemic granulomatous disorder capable of affecting virtually every organ, including the lymph nodes, skin, eyes, heart, liver, spleen, nervous system, and musculoskeletal system. The remarkable diversity of clinical manifestations frequently delays diagnosis and often leads clinicians through a...

Sarcoidosis: The Radiology Interpretation Guide Every Clinician Should Know Sarcoidosis remains one of the most fascinating and diagnostically challenging inflammatory diseases in modern medicine. For radiologists, pulmonologists, emergency physicians, and nuclear medicine specialists, it represents a unique intersection between medical imaging , immune dysregulation, and multisystem disease. A patient may initially present with nothing more than chronic fatigue or mild dyspnea. Yet beneath those subtle symptoms can lie extensive granulomatous inflammation affecting the lungs, mediastinal lymph nodes, heart, eyes, skin, and nervous system. In the era of advanced MRI, CT scan diagnosis , PET imaging, and precision radiology interpretation, understanding sarcoidosis has become increasingly important for accurate and timely diagnosis. This article provides a comprehensive, evidence-based review of sarcoidosis with a strong focus on: CT imaging findings Nuclear medicine imaging Differentia...
