Session Title: Radiation and Cancer: Reality, Extrapolations, Myths & Practice
Question 1: According to UNSCEAR 2010, the contribution of CT examinations to population dose has continued to increase ever since the practice was introduced in the 1970’s
Reference:Paragraph 20 in the Sources and Effects of Ionizing Radiation, United Nations Scientific Committee on Effects of Atomic Radiation (UNSCEAR 2008), Volume 1, published in 2010, United Nations, New York.
Choice A:True.
Choice B:False.
Question 2: There is a significant and systemic practice of inappropriate examination in radiology. Authoritative sources suggest that a significant fraction (20–50% in some areas) of radiological examinations may be inappropriate
Reference:Justification of diagnostic medical exposures: some practical issues. Report of an International Atomic Energy Agency Consultation. Br J Radiol. 2012 May;85(1013):523-538.
Choice A:True.
Choice B:False.
Question 3: When parents (or other caregivers) are provided factual information on potential cancer risks from CT scans in children immediately prior to the examination, which one of the following is most likely?:
Reference:Larsen DB et al. Informing parents about CT radiation exposure in children: it’s OK to tell them. AJR 2007; 189:271-275
Choice A:Many will refuse the examination
Choice B:Most will proceed, with some concern.
Choice C:Most will proceed, with no concern.
Choice D:Most will request a substitute, nonionizing, examination.
Question 4: The tool in which information is hierarchically organized based on anticipated questions/concerns is called:
Reference:Perez M et al. Communication Radiation Risk in Paediatric Imaging. WHO 2016 http://www.who.int/ionizing_radiation/pub_meet/radiation-risks-paediatric-imaging/en/
Choice A:Message mapping
Choice B:Social marketing
Choice C:Social messaging
Choice D:Message marketing
Question 5: Almost no A-bomb survivors received organ doses similar to those from a typical abdominal CT scan.....
Reference:Preston DL, Ron E, Tokuoka S, Funamoto S, Nishi N, Soda M et al. Solid cancer incidence in atomic bomb survivors: 1958-1998. Radiat Res 2007; 168: 1–64.
Choice A:True.
Choice B:False.
Question 6: Recent epidemiological studies of cancer risks associated with pediatric CT scans have produced risk estimates that are inconsistent with those from A-bomb survivors
Reference:Brenner DJ, Hall EJ. Cancer risks from CT scans: Now we have data, what next? Radiology. 2012;265:330-1
Choice A:True.
Choice B:False.
