Controlling the Radiation Dose Received By Patients Undergoing Cardiac Imaging

Assessment of coronary bypass graft patency by first-line multi-detector computed tomography

“…Until recently, high doses were a major limitation of MDCT as first-line imaging in CABG patients, knowing that some of them will undergo CA and possibly PCI soon after the MDCT. Different techniques are available to obtain a low-dose cardiac MDCT [18,19]. The use of prospective scanning was associated with a 69%-reduction in exposure, from 11.2 to 3.5 mSv, in protection-III study [10].…”

Reduction of coronary artery multi-slice computed tomographic radiation and maintained image interpretability by parameter optimization: the multicenter RAMBO study

“…The appropriation of these techniques by interventional or non-interventional cardiologists, most often untrained in radiation protection, has led to exposing both patient and operator to significant doses of radiation, without a real quality control of the practices. A recent editorial (Georges et al, 2011), "Controlling the radiation dose received by patients undergoing cardiac imaging", emphasizes the need to follow the three steps of radiation protection suggested by the International Commission on Radiological Protection (ICRP, 2007): justification, optimization concerning the patient, and dose limitation.…”
