Minimizing radiation dose in coronary CT angiography with diagnostic imaging quality in routine investigation of coronary artery disease

By Dr CE Richards & Dr DR Obaid

The potential for cardiac imaging and evaluating coronary artery disease (CAD) non-invasively has been a key driverbehind the advances incomputed tomography (CT) technologyover the last three decades. Coronary CT angiography (CCTA) now has the diagnostic accuracy to be able to exclude CAD in routine use with high negative predictive power. To extend CCTA to wide-spread usage, including low-risk or even asymptomatic subjects, however requires that high quality images be produced with radiation doses low enough to reduce clinical risk to an absolute minimum [1].
