EDITORIAL Non-invasive coronary imaging: computed tomography or magnetic resonance imaging?

Non-invasive coronary artery imaging has taken a significant step forward with the advent of multislice computed tomography Non-invasive coronary imaging has recentlyseen a rapid expansion of interest, fuelledlargely by technical advances in both computed tomography (CT) and cardiac magnetic resonance imaging (CMR). The race is on for these two modalities to provide routine and robust imaging of coronary arteries in clinical practice. The rate of this progress has inevitably pro-vided a bewildering array of developments, which are hard to stay abreast of. This article will attempt to clarify the fundamental differences between the available techniques, explore their respective capabilities, and discuss future poten-tials
