Mortality rates due to coronary arterial disease (CAD) have declined as result of improved prevention, diagnosis and management, but CAD remains the leading cause of death. Myocardial perfusion scintigraphy (MPS) provides a cost-effective tool for early detection of CAD in symptomatic individuals and can stratify patients according to risk of cardiac events. MPS also provides valuable information to assist clinical decision-making. A large body of evidence supports the current applications of MPS, which has become integral to several guidelines for clinical practice.

Nicol ED, Reyes E, Stanbridge K, Latus K, Robinson C, Rubens MB, Underwood SRet al., 2008, Radiation dose from cardiac investigations: A survey of cardiac trainees and specialists, British Journal of Cardiology, Vol: 15, Pages: 266-268, ISSN: 0969-6113

To identify the knowledge of ionising radiation doses and radiation-related risk in common cardiac procedures among cardiology trainees, cardiologists and general practitioners with a specialist interest in cardiology, a face-to-face questionnaire survey of 47 cardiac specialists, both regular referrers and practitioners of radiation-based procedures, was conducted at the British Cardiovascular Society Annual Conference 2006. Of the 47 medical professionals surveyed, 21 (45%) provided the correct radiation dose for at least one imaging procedure. Most reported doses were below the lower limit of the reference range: the median (interquartile range) radiation dose reported by the respondents was 2 mSv (0.4 to 10 mSv) for coronary angiography (CA) and 6 mSv (1 to 15.8 mSv) for percutaneous coronary intervention (PCI); 2 mSv (0.5 to 15 mSv) and 6 mSv U to 20 mSv) for myocardial perfusion scintigraphy (MPS) and computed tomographic angiography (CTA), respectively. A risk of malignancy from ionising radiation exposure of one in 10,000 for CA (actual risk 1:5,000) and of one in 5,000 for MPS and CTA (actual risk 1:1,000) was reported by the majority of respondents. We conclude that there is significant underestimation of both dose and radiation-related risk to patients. Patients are unable to make informed decisions when consenting for these common procedures, as clinical staff are unaware of the correct radiation dose and associated risk, and therefore ase unable to advise patients properly.
