Abstract:
Sarcoidosis is a multisystem inflammatory disorder characterized by noncaseating granulomas. The diagnosis of sarcoidosis is based on three criteria: clinical history, consistent imaging findings, and histopathology. Radiologists play an important role for the diagnosis and follow-up evaluation of patients with sarcoidosis, which often require a multimodal approach. This imaging essay will explore the typical and atypical imaging manifestations of sarcoidosis at chest radiography, CT, PET/CT, and MRI, provide imaging examples, and discuss relevant differential diagnoses for clinical practice. Keywords: Thorax, MR-Imaging, Staging, PET/CT, CT, Conventional Radiography, Sarcoidosis, Thoracic Imaging, Scintigraphy Supplemental material is available for this article. © RSNA, 2025.

Radiological Investigation III: Pulmonary Angiogram and PET Scan
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
Radiological Investigation II: MRI and Ventilation Perfusion Scan
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
