Cardiac magnetic resonance (CMR) imaging allows high-contrast, spatial, and temporal resolution imaging of the heart and related structures. The absence of ionizing radiation and the greater contrast and temporal resolution…
Today, imagers are presented with more options than ever before for imaging vascular structures throughout the body. This is in part due to the evolution of magnetic resonance angiography (MRA),…
Catheter angiography refers to x-ray imaging of the blood vessels while contrast material is injected through an introducer (needle, catheter, or sheath) positioned within the vessel of interest. First developed…
Many symptoms and signs encountered in the course of clinical care may raise concern for cardiac dysfunction. These manifestations may include chest pain or discomfort, dyspnea, exercise intolerance, edema, syncope,…
Computed tomography angiography (CTA) is an exciting technology that allows noninvasive assessment of the vasculature. Over the past few decades, the use of CTA has grown tremendously due to the…
Ultrasound is the most popular noninvasive imaging technique for evaluation of the vascular system. Vascular ultrasound has significant advantages. It provides comprehensive anatomic and flow details of the vascular system,…
Principles of Nuclear Cardiac Imaging and Performing Single-Photon Emission Computed Tomography and Positron Emission Tomography Studies Cardiac imaging using nuclear techniques plays a critical role in the diagnostic and therapeutic…
Cardiac magnetic resonance imaging (MRI) sequences are numerous, and possible imaging planes are infinite. Each sequence is designed to provide specific information about function, anatomy, or tissue characteristics. Each sequence…
General Principles Cardiac computed tomography (CT) is a specialized form of chest CT. All the technical principles that govern the acquisition and reconstruction of chest CT also apply to cardiac…
Background Despite major advances in other imaging modalities, invasive cardiac catheterization remains a critical component of cardiovascular care. More than 1.1 million cardiac catheterization procedures, in addition to approximately 1.3…
