Overview

Coronary CTA noninvasively visualizes coronary artery stenosis plaque morphology and cardiac anatomy with ECG gating to reduce motion.

Technique

ECG gating heart rate control and contrast timing are essential for diagnostic coronary imaging.

Clinical Uses

Coronary artery disease assessment calcium scoring and preoperative planning for structural interventions.

Limitations and Safety

Radiation and contrast exposure. Heart rate control and patient selection affect image quality.
