CT in ischaemic cardiac disease

Coronary artery disease (CAD) remains the leading cause of death in western nations. Multi-detector CT (MDCT) images obtained with ECG gating are superior to the standard (non-ECGgated) studies due to reduction in blurring secondary to cardiac and respiratory motion, and deliver fast volume coverage and high spatial and temporal resolution. It is recognised as an excellent and robust application for non-invasive assessment of coronary arteries and cardiac structures.

Further technological advancements with third generation scanners have led to combined substantial improvements in image acquisition and analysis with significant reduction in dose.

Updated NICE guidelines now recommend CT coronary angiography as the first-line investigation for all patients who present with typical and atypical angina without known significant coronary artery disease.
