ADVANCES in imaging technology, diagnostic techniques and non-invasive therapeutic techniques have provided physicians with significantly better tools to better diagnose patient diseases and to provide the appropriate treatment. Many of these diagnostic and therapeutic techniques in the area of heart disease involve the use of ionising radiation (harmful radiation) which includes X-rays and radiation from radioactive isotopes injected into the body. While the use of these diagnostic and therapeutic options with ionising radiation in the management of heart diseases have both been indispensable to physicians and beneficial to patients, resulting in decreasing death rates and prolonging survival, repeated exposure to significant doses of radiation may have adverse consequences.
