CCTA
Also written as: CCTA — Coronary Computed Tomography Angiography
Coronary computed tomography angiography; non-invasive CT imaging of coronary arteries using contrast.
Full Definition
Coronary computed tomography angiography is a non-invasive imaging technique that uses multi-detector CT scanners and iodinated contrast to visualize coronary arteries. CCTA provides excellent negative predictive value for excluding significant coronary artery disease and can assess coronary anatomy, plaque characteristics, and stenosis severity. The technique requires ECG gating for cardiac motion compensation and optimal heart rate control. CCTA has become increasingly important in emergency department chest pain evaluation and coronary disease screening.
Usage
Usage note: Distinguish from general CTA (computed tomography angiography) which may refer to non-cardiac vessels.
