These subjects were stratified on age, sex and education. The questionnaire was in\n C<\/jats:styled-content>\n hinese and consisted of 28 questions mostly in multiple choice\/true\u2010or\u2010false format, divided into three sections examining demographic data, radiation knowledge\/awareness and expectations.\n <\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n A total of 173 questionnaires were returned (83 females and 84 females; mean age of 53). Of these, 32.6% had attended college, 32.6% had completed matriculation and 24.4% secondary school. Most subjects underwent\n CT<\/jats:styled-content>\n (75),\n MRI<\/jats:styled-content>\n (70) and\n PET\u2010CT<\/jats:styled-content>\n (18). Education significantly affected the radiation knowledge (\n P<\/jats:italic>\n \u2009=\u20090.013). 60.7% and 32.7% were not aware of the radiation\u2010free nature of\n MRI<\/jats:styled-content>\n and\n USG<\/jats:styled-content>\n , respectively. Respectively, 45.4% and 43.5% were of the misconception that Barium enema and Barium swallow studies do not involve radiation. Moreover, 77.6% and 87.9% were aware of the radiation\u2010laden nature of\n CT<\/jats:styled-content>\n and plain\n X<\/jats:styled-content>\n \u2010rays, respectively. Furthermore, 34% and 50%, respectively, think that they are not exposed to radiation at home and on a plane. Regarding the fatal cancer risk from\n CT<\/jats:styled-content>\n , 17.8% chose the correct answer and 62% underestimated the risk. 32.2% correctly estimated the equivalent dose of\n CT<\/jats:styled-content>\n in terms of number of conventional\n X<\/jats:styled-content>\n \u2010rays and 43.2% underestimated the dose. Most (98.2%) were told of the indication, and 42.7% were told the associated radiation dose.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n Patient radiation awareness is unsatisfactory. There is need to increase patient radiation awareness, and to provide them with the necessary information.<\/jats:p>\n <\/jats:sec>","DOI":"10.1111\/j.1754-9485.2012.02471.x","type":"journal-article","created":{"date-parts":[[2012,11,5]],"date-time":"2012-11-05T05:26:12Z","timestamp":1352093172000},"page":"38-44","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":43,"title":["Assessing local patients' knowledge and awareness of radiation dose and risks associated with medical imaging: A questionnaire study"],"prefix":"10.1111","volume":"57","author":[{"given":"Ho\u2010kwan","family":"Sin","sequence":"first","affiliation":[{"name":"Medical and Geriatric Department Kwong Wah Hospital Hong Kong"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chun\u2010Sing","family":"Wong","sequence":"additional","affiliation":[{"name":"Department of Diagnostic Radiology The University of Hong Kong Hong Kong"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bingsheng","family":"Huang","sequence":"additional","affiliation":[{"name":"Department of Diagnostic Radiology The University of Hong Kong Hong Kong"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ka\u2010ling","family":"Yiu","sequence":"additional","affiliation":[{"name":"Department of Medicine North District Hospital Hong Kong"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wai\u2010lam","family":"Wong","sequence":"additional","affiliation":[{"name":"Accident & Emergency Department Tuen Mun Hospital Hong Kong"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yiu Ching Tiffany","family":"Chu","sequence":"additional","affiliation":[{"name":"Radiology Department Kwong Wah Hospital Hong Kong"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2012,11,5]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMra072149"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.2235592100"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00247-006-0170-x"},{"key":"e_1_2_6_5_1","unstructured":"United Nations Scientific Committee on the Effects of Atomic Radiation.Annex D: medical radiation exposures.
