Abstract
Introduction: There have been several national and international publications relating to patient dose management, predominantly in the United States and European countries.1,2 In South Australia, no recent study has been published surveying common adult CT examinations. This study aims to establish a faculty reference level (FRL) for one scanner in our institution.Methods: Data was retrospectively collected from our Toshiba Aquilion One Vision 320-slice from 26 December 2016 to 26 June 2017. Examinations were separated as contrast or non-contrast studies, and single phase or multi-phases. Common CT examinations, including chest, chest/abdomen/pelvis, and abdomen/pelvis were reported. The median, mean (50th percentile) and 75th percentile for the dose spread were calculated according to the examination.Results: There was a total of 1571 CT examinations performed between 26 December 2016 and 26 June 2017 using the Toshiba scanner in our institution; 262 of these examinations met the inclusion and exclusion criteria. The examinations for our Toshiba scanner (established as median value of CTDIvol and DLP) were distributed as CT chest contrast (n = 67, 25.6%, 6 mGy, 219.1 mGy.cm), CT chest non-contrast (n = 41, 15.6%, 5.7 mGy, 190.6 mGy), CT abdomen/pelvis contrast (single phase) (n = 49, 18.7%, 6.5 mGy, 330.5 mGy.cm), CT abdomen/pelvis contrast (multi-phase) (n = 33, 12.6%, 8.93 mGy, 1037.5 mGy.cm), CT abdomen/pelvis non-contrast (n = 12, 4.6%, 10.1 mGy, 289.9 mGy.cm) and CT chest/abdomen/pelvis (n = 60, 22.9%, 7.15 mGy, 619.4 mGy.cm).Conclusion: This data provided information that our own institution and others can use for quality improvement activities. Future research is required to allow for analysis to include more CT examinations in various scanners.

| Other | It is our great pleasure to welcome you all to the 22nd Asia-Australasia Conference of Radiological Technologists (AACRT 2019) in conjunction with the Australian Society of Medical Imaging and Radiation Therapy’s 14th National Conference (ASMIRT 2019), to be held at Adelaide Convention Centre, from 28-31 March 2019. The theme of ASMIRT / AACRT 2019 is Better Together - patients, professionals, possibilities. The theme is focused on bringing people together to share information on the latest technologies, of smart ways to use the resources we have for the best possible patient outcomes, and of course to socialise together and make long term friendships and networks – to better our profession, our patients and for our future possibilities. The combination of the ASMIRT 2019 Conference and the ISRRT’s 22nd Asia Australasia Conference of Radiological Technologists allows for additional international networking and collaboration. The conference will feature a comprehensive industry exhibition showcasing the latest medical radiation science technologies, up to six concurrent technical sessions over three days, international keynote speakers, a student conference, a vibrant and inclusive social program and a variety of pre-conference workshops and site visits of some of the southern hemispheres leading medical research institutions, all within easy walking distance of the Adelaide Convention Centre. This conference promises to be a great experience where we will all be ‘Better Together”. |
