Acute coronary syndrome
Acute coronary syndrome (ACS) is a syndrome (set of signs and symptoms) due to decreased blood flow in the coronary arteries such that part of the heart muscle is unable to function properly or dies.

Angiography
Angiography or arteriography is a medical imaging technique used to visualize the inside, or lumen, of blood vessels and organs of the body, with particular interest in the arteries, veins and the heart chambers.

Background radiation
Background radiation is a measure of the ionizing radiation present in the environment at a particular location which is not due to deliberate introduction of radiation sources.

Circulatory system
The circulatory system, also called the cardiovascular system or the vascular system, is an organ system that permits blood to circulate and transport nutrients (such as amino acids and electrolytes), oxygen, carbon dioxide, hormones, and blood cells to and from the cells in the body to provide nourishment and help in fighting diseases, stabilize temperature and pH, and maintain homeostasis.

Computed tomography angiography
Computed tomography angiography (also called CT angiography or CTA) is a computed tomography technique used to visualize arterial and venous vessels throughout the body.

Coronary arteries
The coronary arteries are the arteries of the coronary circulation that transport blood into and out of the cardiac muscle.

Coronary artery bypass surgery
Coronary artery bypass surgery, also known as coronary artery bypass graft (CABG, pronounced "cabbage") surgery, and colloquially heart bypass or bypass surgery, is a surgical procedure to restore normal blood flow to an obstructed coronary artery.

Coronary artery disease
Coronary artery disease (CAD), also known as ischemic heart disease (IHD), refers to a group of diseases which includes stable angina, unstable angina, myocardial infarction, and sudden cardiac death.

Coronary catheterization
A coronary catheterization is a minimally invasive procedure to access the coronary circulation and blood filled chambers of the heart using a catheter.
New!!: Coronary CT angiography and Coronary catheterization · See more »
Coronary CT calcium scan
A coronary CT calcium scan is a computed tomography (CT) scan of the heart for the assessment of severity of coronary artery disease.
New!!: Coronary CT angiography and Coronary CT calcium scan · See more »
Coronary stent
A coronary stent is a tube-shaped device placed in the coronary arteries that supply blood to the heart, to keep the arteries open in the treatment of coronary heart disease.
New!!: Coronary CT angiography and Coronary stent · See more »
CT scan
A CT scan, also known as computed tomography scan, makes use of computer-processed combinations of many X-ray measurements taken from different angles to produce cross-sectional (tomographic) images (virtual "slices") of specific areas of a scanned object, allowing the user to see inside the object without cutting.

Fractional flow reserve
Fractional flow reserve (FFR) is a technique used in coronary catheterization to measure pressure differences across a coronary artery stenosis (narrowing, usually due to atherosclerosis) to determine the likelihood that the stenosis impedes oxygen delivery to the heart muscle (myocardial ischemia).
New!!: Coronary CT angiography and Fractional flow reserve · See more »
Heart
The heart is a muscular organ in most animals, which pumps blood through the blood vessels of the circulatory system.
New!!: Coronary CT angiography and Heart · See more »
Heart arrhythmia
Heart arrhythmia (also known as arrhythmia, dysrhythmia, or irregular heartbeat) is a group of conditions in which the heartbeat is irregular, too fast, or too slow.

Intravascular ultrasound
Intravascular ultrasound (IVUS) is a medical imaging methodology using a specially designed catheter with a miniaturized ultrasound probe attached to the distal end of the catheter.

Intravenous therapy
Intravenous therapy (IV) is a therapy that delivers liquid substances directly into a vein (intra- + ven- + -ous).

Medical imaging in pregnancy
Medical imaging in pregnancy may be indicated because of pregnancy complications, intercurrent diseases or routine prenatal care.

Motion blur
Motion blur is the apparent streaking of moving objects in a photograph or a sequence of frames, such as a film or animation.

Positive and negative predictive values
The positive and negative predictive values (PPV and NPV respectively) are the proportions of positive and negative results in statistics and diagnostic tests that are true positive and true negative results, respectively.
New!!: Coronary CT angiography and Positive and negative predictive values · See more »
Radiocontrast agent
Radiocontrast agents are substances used to enhance the visibility of internal structures in X-ray-based imaging techniques such as computed tomography (contrast CT), projectional radiography, and fluoroscopy.

Sievert
The sievert (symbol: SvNot be confused with the sverdrup or the svedberg, two non-SI units that sometimes use the same symbol.) is a derived unit of ionizing radiation dose in the International System of Units (SI) and is a measure of the health effect of low levels of ionizing radiation on the human body.

Tachycardia
Tachycardia, also called tachyarrhythmia, is a heart rate that exceeds the normal resting rate.

Temporal resolution
Temporal resolution (TR) refers to the precision of a measurement with respect to time.
