Invasive coronary angiography (ICA) has served as the "gold standard" for coronary artery disease diagnosis over the past two decades. The recent British Cardiovascular Society Working Group report on the role of non-invasive imaging, published in Heart, proposes that developments in non-invasive testing now challenge the primacy of ICA.¹ Non-invasive testing modalities, such as exercise tolerance testing (ETT), myocardial perfusion scintigraphy (MPS), stress echocardiography (SE), cardiac computed tomography (CT) and cardiovascular magnetic resonance (CMR), offer alternative approaches to evaluate aspects of cardiac anatomy and physiology, while avoiding the morbidity, costs and risks of major complications from ICA.

Since selection of the optimal diagnostic test for a particular patient requires an assessment of the benefits and risks to the patient of each test under consideration, as well as the benefits and risks of not performing any testing, an understanding of the risks from ionising radiation can play an important role in . . .
