Positron emission tomography
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…
CARDIOVASCULAR IMAGING
Single photon emission computed tomography
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…
Pulmonary, Mediastinal, Vascular, and Chest Wall MRI
▪ 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….
Imaging Anatomy of the Heart and Thoracic Great Vessels
▪ 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…
Pulmonary CT: The Scanner, the Protocol, and the Dose
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),…
Cardiovascular CT
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…
Radiographic Techniques
■ 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…
Step-by-Step Analysis of Cardiac Chambers in CT
■ 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…
Mediastinum, Chest Wall, and Diaphragm
■ 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…
Normal Anatomy of the Lungs
▪ Introduction The lungs incorporate the parenchyma, vasculature, bronchial tree (trachea, bronchi, and bronchioles), and a network of investing connective tissue that supports and connects the structures to one another….
