E Science News -- Numerous radiology practices were able to significantly reduce the radiation dose associated with multi-detector computed tomography (MDCT) scans by participating in a one day dose optimization workshop provided by the Royal Australian and New Zealand College of Radiologists (RANZCR) and supported by the local state health department, according to a study in the August issue of the Journal of the American College of Radiology (www.jacr.org). Ten hospital-based public and private sector radiology practices in Queensland, Australia, participated in the study. A one day feedback and optimization training workshop was conducted for participating practices and was attended by the radiologist and medical imaging technologist responsible for the project at each site.
