CCTA
Also written as: CCTA — coronary computed tomography angiography
Non-invasive cardiac imaging that visualizes coronary arteries using computed tomography with contrast enhancement.
Full Definition
Coronary computed tomography angiography is a non-invasive imaging technique that provides detailed visualization of the coronary arteries using CT technology with intravenous contrast material. CCTA can detect both calcified and non-calcified coronary plaques, assess stenosis severity, and evaluate plaque characteristics. It serves as an important tool in cardiovascular risk stratification and is increasingly used for screening intermediate-risk patients and evaluating chest pain in emergency settings.
Usage
Usage note: Distinguish from CTCA (computed tomography coronary angiography), which uses the same acronym letters in different order.
