Introduction The use of ionising radiation within cardiology is widespread with both myocardial perfusion scintigraphy (MPS) and conventional invasive coronary angiography (CA) being common diagnostic investigations for coronary artery disease. In the UK, some 70,000 MPS were performed in 20001 and over 205,000 CA in 2005.2 The use of ionising radiation is likely to increase further with the advent of cardiac multi-detector X-ray computed tomography (MDCT) and X-ray computed tomographic angiography (CTA). Furthermore, all these investigations are deemed to involve moderate- or high-dose radiation.3 Previous studies have shown poor knowledge o
