Introduction and Background Although different in appearances on imaging, radiation and drug-induced lung diseases share several similarities. Both entities may present with a variety of appearances, both in the acute…
Introduction Eosinophilic lung diseases are characterized by the presence of pulmonary opacities and peripheral blood eosinophilia, tissue eosinophilia, or both. Eosinophils are leukocytes that are involved in immune defense and…
■ Introduction Certain diffuse lung diseases are associated with high- or low-attenuation lesions. High-attenuation lesions are most often due to calcium deposition from a variety of mechanisms, but can also…
Introduction Hypersensitivity pneumonitis is an immunologically mediated lung disease that occurs in susceptible sensitized individuals following inhalational exposure to antigenic organic dust. As such, the antigenic material must be small…
▪ Introduction and Background: Considerations for Using MRI Magnetic resonance imaging (MRI) is an important tool in imaging the mediastinum, chest wall, and chest vasculature, with a continuously expanding role….
Air Space Disease Acute Consolidation Air space consolidation results when alveoli are filled with material that attenuates the x-ray beam more than the surrounding lung parenchyma. When encountered in the…
Introduction The bony thoracic cage and crowded vital organs in the thorax make open surgical access difficult and challenging. For these same reasons, the thorax is ideal for image-guided interventions….
Introduction Historically, radionuclide lung imaging was used mainly for the diagnosis of pulmonary embolism (PE) and lung function. The advent of fluorodeoxyglucose (FDG) positron emission tomography (PET) computed tomography (CT)…
▪ Introduction Various imaging techniques are used in the assessment of the normal anatomy and pathology of the heart and great vessels. Chest radiography is the most commonly used modality…
Introduction Radionuclide myocardial perfusion imaging (MPI) plays a key role in the diagnosis and management of individuals with known or suspected coronary artery disease (CAD). Recent breakthroughs in single-photon emission…
