What is the Origin of Coronary CT Angiography?

This clinical term combines 'Coronary' (relating to the heart's arteries), 'CT' (Computed Tomography), and 'Angiography' (the visualization of blood vessels), reflecting its method and target. Its development is a product of advancements in diagnostic radiology and cardiac imaging technology.

What is the Mechanism of Coronary CT Angiography?

A contrast agent is injected into a peripheral vein, rapidly filling the coronary arteries. The CT scanner, synchronized with the patient's heart rhythm, acquires rapid, sequential X-ray data as the contrast flows through the vessels. A powerful computer then reconstructs this data into detailed cross-sectional and 3D images. This process enables the precise measurement of plaque burden and luminal narrowing, providing a vital snapshot of the vascular health status.

Coronary CT Angiography

Meaning

Coronary CT Angiography (CCTA) is a non-invasive, advanced medical imaging technique that uses Computed Tomography (CT) and intravenous contrast material to generate high-resolution, three-dimensional images of the coronary arteries. This diagnostic tool allows clinicians to visualize the presence and extent of atherosclerotic plaque buildup and stenosis within the vessel walls. CCTA provides essential anatomical information for assessing cardiovascular risk, a factor closely intertwined with hormonal and metabolic health.
