The necessity of quality assurance and quality management programs in diagnostic and therapeutic radiology a review of some abnormal occurrences in the USA

During 1990, 467 medical radiology mis administration cases, involving 573 patients, were reported to the Nuclear Regulatory Commission in the USA. Of the 467, 443 cases were related to diagnostic radiology and 24 to radiation therapy. Details on these events were reported by the NRC's Office for Analysis and Evaluation of Operational Data (AEOD). This office serves also as the NRC's center for the independent assessment of operational events. The above data were taken from the medical mis administration report of the AEOD office. Several cases from this report were mentioned also in the NRC's 1991 Annual Report. (authors)
