KEY POINTS • Before ordering any test, especially one associated with ionizing radiation, we must ensure the appropriateness of the study and that the potential benefits outweigh the risks. •…
KEY POINTS • The radionuclides of interest for PET emit positrons, the antiparticles of electrons. • Positrons interact with free electrons to produce two back-to-back 511-keV annihilation photons; PET imaging…
KEY POINTS • Conventional gamma cameras use one to three detectors, based on a NaI scintillation crystal and a photomultiplier tube array, that rotate around the patient. • Cameras commonly…
▪ 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….
▪ 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 CT has become an indispensable part of diagnostic imaging in recent times. With the help of the money that the Beatles’ records made for Electrical and Music Industries (EMI),…
Introduction CT imaging of the heart plays an important role in anatomic and sometimes functional evaluation of the heart and coronary arteries. Coronary artery cardiac CT angiography (CTA) has substantially…
■ Conventional Chest X-Ray The chest radiograph is the most common radiographic procedure performed in the imaging department and is the initial imaging modality in a patient presenting with thoracic…
■ Introduction Heart disease is a leading cause of morbidity and mortality worldwide. Noninvasive imaging plays a role in the diagnosis, monitoring, and treatment of heart disease. Hence, radiologists can…
■ Introduction The mediastinum, chest wall, and diaphragm can be evaluated by multiple imaging modalities, such as radiography, computed tomography (CT), and magnetic resonance imaging (MRI). The chest radiograph is…
