The health detriment arising from the radiation dose associated with CT has been quantified in terms of the number of likely cases of serious health effects. The results show that a significant saving in the collective radiation dose is possible, with an associated detriment of between 0.23 and 0.33 cases of cancer or severe hereditary effects averted in one imaging department every year. In selecting the balance of provision of MRI and CT facilities, the health detriment associated with the radiation dose from CT should be considered.<\/jats:p>","DOI":"10.1259\/bjr.74.886.740926","type":"journal-article","created":{"date-parts":[[2014,6,13]],"date-time":"2014-06-13T02:13:40Z","timestamp":1402625620000},"page":"926-931","source":"Crossref","is-referenced-by-count":24,"title":["Provision of MRI can significantly reduce CT collective dose"],"prefix":"10.1093","volume":"74","author":[{"given":"J C","family":"Clarke","sequence":"first","affiliation":[{"name":"Departments of 1Radiology and 3Neuroradiology, Royal Group of Hospitals, Belfast BT12 6BA, 2Northern Ireland Regional Medical Physics Agency, Forster Green Hospital, Belfast BT8 6HD and 4Northern Ireland Regional Medical Physics Agency, Headquarters, Belfast BT2 8BS, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"K","family":"Cranley","sequence":"additional","affiliation":[{"name":"Departments of 1Radiology and 3Neuroradiology, Royal Group of Hospitals, Belfast BT12 6BA, 2Northern Ireland Regional Medical Physics Agency, Forster Green Hospital, Belfast BT8 6HD and 4Northern Ireland Regional Medical Physics Agency, Headquarters, Belfast BT2 8BS, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"B E","family":"Kelly","sequence":"additional","affiliation":[{"name":"Departments of 1Radiology and 3Neuroradiology, Royal Group of Hospitals, Belfast BT12 6BA, 2Northern Ireland Regional Medical Physics Agency, Forster Green Hospital, Belfast BT8 6HD and 4Northern Ireland Regional Medical Physics Agency, Headquarters, Belfast BT2 8BS, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"K","family":"Bell","sequence":"additional","affiliation":[{"name":"Departments of 1Radiology and 3Neuroradiology, Royal Group of Hospitals, Belfast BT12 6BA, 2Northern Ireland Regional Medical Physics Agency, Forster Green Hospital, Belfast BT8 6HD and 4Northern Ireland Regional Medical Physics Agency, Headquarters, Belfast BT2 8BS, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"P H S","family":"Smith","sequence":"additional","affiliation":[{"name":"Departments of 1Radiology and 3Neuroradiology, Royal Group of Hospitals, Belfast BT12 6BA, 2Northern Ireland Regional Medical Physics Agency, Forster Green Hospital, Belfast BT8 6HD and 4Northern Ireland Regional Medical Physics Agency, Headquarters, Belfast BT2 8BS, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2014,3,5]]},"reference":[{"key":"2025060608120637700_R1","unstructured":"Royal College of Radiologists\/National Radiological Protection Board.
