RESUMO
Objective: Determine how many radiology resident research day projects are presented at the Canadian Association of Radiologists Annual Scientific Meeting (CAR ASM) and if presentation at the CAR ASM is associated with increased rates of publication. Methods: A database of radiology resident presentations from 2012 to 2017 research days at seven Canadian radiology programs was utilized. Each presenting resident was searched for in 2011-2019 CAR ASM books of abstracts to identify all CAR ASM presentations both related to and separate from their research day projects. These presentations were matched with resident research day presentations and their publication status. Descriptive statistical analysis and calculation of relative risk (RR) between publication of research day projects and presentation at CAR was performed. Results: 208 residents presented 288 projects at internal research days. 93 of the 208 residents had a total of 195 presentations at CAR (mean .94 +/- 1.91 SD). 36 of the 288 (13%) research day projects were presented at a CAR ASM, of which 18/36 (50%) were published. 83 of the 252 (32%) research day projects not presented at CAR were published. CAR ASM presentation of a research day project was associated with an increased rate of publication (RR 1.537 P=.0396). There was no significant association between research day project publication and unrelated CAR ASM presentations (P=.275). Most research day projects both presented at CAR ASM and published (56%) were in the Canadian Association of Radiologists Journal. Conclusion: CAR ASM presentation of research day projects is associated with an increased rate of publication.

Wrist trauma is common in children, typically requiring radiography for diagnosis and treatment planning. However, many children do not have fractures and are unnecessarily exposed to radiation. Ultrasound performed at bedside could detect fractures prior to radiography. Modern tools including three-dimensional ultrasound (3DUS) and artificial intelligence (AI) have not yet been applied to this task. Our purpose was to assess (1) feasibility, reliability, and accuracy of 3DUS for detection of pediatric wrist fractures, and (2) accuracy of automated fracture detection via AI from 3DUS sweeps. Children presenting to an emergency department with unilateral upper extremity injury to the wrist region were scanned on both the affected and unaffected limb. Radiographs of the symptomatic limb were obtained for comparison. Ultrasound scans were read by three individuals to determine reliability. An AI network was trained and compared against the human readers. Thirty participants were enrolled, resulting in scans from fifty-five wrists. Readers had a combined sensitivity of 1.00 and specificity of 0.90 for fractures. AI interpretation was indistinguishable from human interpretation, with all fractures detected in the test set of 36 images (sensitivity = 1.0). The high sensitivity of 3D ultrasound and automated AI ultrasound interpretation suggests that ultrasound could potentially rule out fractures in the emergency department.
RESUMO
OBJECTIVE: Twenty-one previous studies have shown a mean presentation to publication conversion rates at radiology conferences of 26%. There have been no prior studies on publication of medical imaging residency research presentations. Our objective was to determine how many medical imaging resident research projects presented at internal program research days across Canada go on to publication. METHODS: A list of unique medical imaging resident research presentations given at program research days during the 2012-2013 to 2016-2017 academic years was generated via e-mail contact of programs or review of publicly available data on program websites. Unique resident presentations were identified and publications associated with these presentations were sought via database and Internet searching. The number of publications, publishing journals, and time to publication was determined. RESULTS: Data from 32 research days at 7 programs were assessed. A total of 287 resident presentations were identified. Of these 287 presentations, 99 had associated publications (34% presentation to publication conversation rate), with variation in presentation numbers and publication conversion rates between schools. These 99 presentations were associated with a total of 118 publications in a total of 57 different journals. Time from presentation to publication was calculable for 109 of the 118 articles. Fifteen (14%) were published before research day and 94 (86%) were published after research day with a mean time to publication of 12.3 ± 13.6 months for all articles. CONCLUSIONS: Thirty-four percent of resident research presentations at Canadian medical imaging program research days go on to publication.
