20 th ISRRT World Congress 2018 Hosted by Website: www.isrrt2018.org.tt Email: queries@isrrt2018.org.tt Conclusion: These verifications of the radiation shielding barriers’ effectiveness were within the stipulated standards and well below calculated outcome. COMPUTED TOMOGRAPHY Digital Training Platform for Chest Image Interpretation: An RCT CT2-1 Dr. Sonyia McFadden, Ms. Laura McLaughlin, Dr. Ciara Hughes, Dr. Raymond Bond, Dr. Jonathan McConnell, Dr. Nicholas Woznitza, Mr. Andrew Cairns, Dr. Ayman Elsayed Ulster University, Northern Ireland Purpose: Time delays and errors exist within image interpretation which lead to delays in patient care and misdiagnosis. However, little research has tested training guides and no research has been performed on chest image interpretation training based on eye tracking technology. Methods: Reporting radiographers interpreted 20 chest images during pre and post intervention interpretation sessions (n=320). Participants within the intervention group had access to a digital training platform for nine months following their initial assessment. The training platform included a digital search strategy training tool and an educational multimedia tool to communicate the search strategies using eye tracking technology. The interpretation sessions were completed using eye tracking technology and whilst thinking aloud. An online survey gathered feedback on the platform. Results: Both groups increased true negative (TN) rates following the test period. Intervention group TN’s increased from approximately 54.5% to 65% and control group increased from 47.7% to 77.5% (p=0.015). True positive (TP) rate increased within the intervention group from 30.6% to 47.5% following the test period, whereas the TP rate of the control group decreased following the test period from 44.4% to 30.0%. False positive (FP) rate decreased for both groups, in the intervention group from 45.5% to 35.0% and in the control group also from 52.3% to 22.5% following the test period (p=0.006). Both groups were more confident in their provided diagnosis following the test period, this increased most in the intervention group, increasing from a mean of 4.4/10 to 5.4/10. Participants found the training platform useful however they commented on the difficulty in finding time to use it. Conclusion: Confidence increased most in the intervention group. Some improvements were noted in participant performance following access to the tool, however the training platform needs to be tested with a larger group of participants. Enhancing Radiographer Threshold CT Competencies through Clinical Simulation Maryann Hardy 1 , Martine Harris 1 Professor, University of Bradford, UK CT2-2 Purpose: The last decade has seen extensive growth of Computed Tomography (CT) place greater expectations on radiographers to participate in CT image acquisition early in their careers. Pre-qualification technical skills development is achieved through the integration of academic and clinical learning but pressures on health service capacity limit opportunities for students to obtain practical experience. Practice simulation has been shown to be beneficial to learning but limited opportunities exist in relation to CT skills development. This proof of concept study explore whether a bespoke CT simulation web platform could increase student confidence and competence in non-contrast head acquisition. Methods: Supported by funding from Health Education England, an integrated CT simulation programme distributed through the internet was developed. This programme reflected current clinical CT practice taking the student from patient registration through to discharge requiring decision making on image acquisition and reconstruction processes. Both practice and assessment modes were incorporated into the programme for monitoring student CT skills development and errors in decision-making. 20 th International Society of Radiographers and Radiological Technologist, World Congress April 12 – 15, 2018 • Hyatt Regency Trinidad, Wrightson Road, Port of Spain, Trinidad, W.I.

20 th ISRRT World Congress 2018 Hosted by Website: www.isrrt2018.org.tt Email: queries@isrrt2018.org.tt Results: The CT simulation programme enabled students to practice their clinical skills and see the consequences of errors in parameter choice on image quality. Students reported greater confidence in CT processes prior to clinical placement and ability to questions clinical radiographers from a wider knowledge base. Conclusions: CT simulation technologies that enable errors in judgement to be made, and consequences appreciated, increase fundamental knowledge and understanding of the technology. Expansion of the CT simulation programme to include chest imaging is being explored. Drop-In CT for Intensive Care Patients Kim Storm Rasmussen 1 , Birthe Degn 2 , Bo Mussmann 3 1 Specialist Radiographer, 2 Head of CT, Master of learning processes, 3 Research radiographer, PhD Odense University Hospital, Denmark CT2-3 Purpose: CT examinations in critically ill patients demand coordination between the intensive care units (ICU) and the radiology department and often the ICU will interrupt ongoing medical treatment to allow the patient to be scanned when a time slot is open at the radiology department. Furthermore, the scanner will be blocked while the patient is being transported to the radiology department.Thus, the scanner capacity is not used effectively.The primary purpose of the study was to establish a procedure where the CTexamination would not interfere negatively with the treatment plan. The secondary purpose was to evaluate if the patients were scanned without waiting time and to evaluate the use of the scanner capacity. Methods: We introduced a drop-in system where the ICUs prepare the patient when appropriate with regard to the treatment plan. Without prior notice the ICU calls the CT-booking office and announces that the patient arrives in CT within 10 minutes. The CT-team will then finish the current examination and prepare for the ICU scan. Results: During 5 months we scanned a total of 91 ICU patients (39 CT-head, 39 chest/abdomen and 13 miscellaneous) none of which had any waiting time. 2 Time spent on one patient dropped from approximately 40 to 20 minutes on average. The radiology department spent very little time coordinating, except when the ICU staff were unfamiliar with the new procedure and called in advance to arrange specific time slots for CT. In a few cases two patients arrived at the same time, but they were still scanned immediately because it was possible to clear another scanner. Conclusion: Drop-in CT works well for ICU-patients and the procedure meets the needs of both ICU and radiology departments. ICU-patients can be scanned without waiting time and the scanner capacity can be more effectively used. GENERAL IMAGING Advances in Radiation in Guyana: Academic and Regulatory Perspectives Petal Surujpaul Medical Physicist, Georgetown Public Hospital Corporation, Guyana GI2-1 Purpose: A four-year intense journey through the various advancements and challenges faced in Guyana as we transcend from initiating academic emphasis on a Bachelors of Science in Medical Imaging, towards obtaining membership from the IAEA, and now developing regulatory requirements for both medical and industrial sectors. Newer more solicited aspects include extensive aspects of diverse research, along with the student’s and collaborative institutional inputs. Regulatory requirements are not yet formally in existence for Industrial radiography and radioactive sources use, but have been recently implemented in radiotherapy for the health sector. The mining areas are predominant users of radioactive sources which have now pushed the government to place some much needed emphasis on regulatory requirements for transport, handling, storage and use of same. IAEA’s strategic input has been a guidance tool in implementing radiation protective measures by first starting with the radioactive source inventory, detection methods, radiation emergency preparation and capacity building for port health and occupationally exposed workers. 20 th International Society of Radiographers and Radiological Technologist, World Congress April 12 – 15, 2018 • Hyatt Regency Trinidad, Wrightson Road, Port of Spain, Trinidad, W.I.
