Rationale And Objectives: Picture archiving and communication system (PACS) is integral to radiology, yet effective training to master PACS viewer tools remains challenging. This study aimed to evaluate the impact of a video-based curriculum on radiology residents' PACS confidence and technical proficiency.
Materials And Methods: A prospective cohort study was conducted at a tertiary academic institution during 2022-2023, enrolling first-year (R1) and second-year (R2) radiology residents. The Intervention Group received a 30-minute instructional video on PACS tools 3 months after their orientation. The Reference Group did not receive additional training. Comfort levels and PACS task performance were assessed before and after the intervention.
Results: A total of 24 residents participated, with 12 in each group. The Intervention Group showed a significant increase in self-reported confidence in PACS skills following the video intervention (median [interquartile range]=-1.01 [-1.30, -0.43] vs. 2.07 [1.37, 2.38], p<0.01). The Intervention Group maintained a higher confidence level at the R2 level compared to the Reference Group, though the difference was not statistically significant. Additionally, the Intervention Group completed their assigned PACS tasks in significantly less time (total time: 220.5 s [179.5, 259.5] vs. 315.0 s [211.8, 397.0], p=0.04).
Conclusion: The video-based PACS curriculum effectively improved radiology residents' technical skills and confidence. These results highlight the importance of supplementing on-the-job learning with formal technical training to reinforce proficiency with the PACS viewer.

Background: Prior research linking myosteatosis with cognition in older adults has been conducted in relatively homogenous populations with narrow age ranges. We evaluated if abdominal myosteatosis was associated with processing speed in a multiethnic cohort of middle aged and older adults.
Methods: The sample included 1,268 adults (46-86 years-old, mean 63±9 years, 53 % female, 41 % White, 20 % Black, 14 % Chinese, and 25 % Hispanic), a subset from the Multi-Ethnic Study of Atherosclerosis.

Introduction: There are uncertainties about whether current advanced-level courses provide the knowledge needed to develop the profession for radiographers in Sweden. The aim of this study was to investigate Swedish radiographers' perceived need for additional post-registration knowledge in their profession and their need for education at advanced level.
Methods: Swedish radiographers were invited to participate in a national electronic survey between November and December 2022.
