Estimating 3D supraspinatus intramuscular fatty infiltration in older adults: a pilot study.

BACKGROUND: A recent report suggests that semi-quantitative two-dimensional Goutallier grade (2D-GG) correlates poorly with quantitative three-dimensional Dixon fat fraction (3D-Dixon-FF) on magnetic resonance imaging (MRI). PURPOSE: To determine whether the finding of poor correlation of supraspinatus 3D-Dixon-FF with 2D-GG is reproducible, and to determine the strength of the correlation of 3D-Dixon-FF with quantitative 2D Dixon fat fraction (2D-Dixon-FF). MATERIAL AND METHODS: Ten adults aged ≥60 years were recruited prospectively received shoulder MRI. 2D-Dixon-FF and 3D-Dixon-FF were measured on 6-point Dixon fat fraction maps. 2D-GG was rated on T1-weighted images. RESULTS: The mean age of participants was 70.7 ± 3.7 years. The mean 3D-Dixon-FF was 8.3% ± 5.7%; the mean 2D-Dixon-FF was 7.3% ± 4.4%; and the mean 2D-GG was 0.9 ± 0.7. There was a strong correlation for 3D-Dixon-FF with 2D-Dixon-FF (rho = 0.90; P < 0.001) and with 2D-GG (rho = 0.73; P = 0.017). Excellent inter-observer reliability was found for Dixon fat fraction (intraclass correlation coefficient = 0.946), which was good for Goutallier grade (weighted kappa = 0.634). CONCLUSION: Supraspinatus 3D-Dixon-FF had a strong correlation with 2D-Dixon-FF and 2D-GG in our study population.

Virtual Radiology Readouts After the Coronavirus Disease (COVID-19) Pandemic.

Social distancing concerns arising from the coronavirus disease (COVID-19) pandemic have led to the emergence of virtual readouts in radiology training programs. Given the myriad benefits of virtual readouts, radiology departments should continue using virtual readouts in at least a hybrid format, even after social distancing restrictions become relaxed. This article highlights the challenges and opportunities associated with virtual readouts and provides guidance and strategies for their long-term implementation by training programs.

A Radiology Trainee's Guide to Unique Opportunities Offered by the Radiological Society of North America.

The Radiological Society of North America (RSNA) offers educational resources and career development opportunities through many opportunities for trainees. However, trainees frequently lack access to or awareness of these opportunities and requirements. The purpose of this article is to promote access to RSNA trainee opportunities by illustrating their qualifications, advantages, and characteristics. Access to opportunities starts with RSNA membership, which grants access to several educational, research, and career development offerings. One focal point of RSNA opportunities is the RSNA Annual Meeting in Chicago, Ill, which provides several trainee-specific events. RSNA educational opportunities include access to board preparation content and information about emerging radiologic technologies. Research opportunities include mentor pairing, project development workshops, venues for presentation and publication, and the William W. Olmsted Editorial Fellowship for Trainees. Career development opportunities include positions for society involvement, leadership, and job searching. Collectively, the information presented in this article can guide the approach to early radiology career development for interested medical students, residents, fellows, and faculty advisers. ©RSNA, 2020.

Imaging Patterns of Injuries After the 2015 Amtrak Philadelphia Train Derailment.

OBJECTIVE: The purpose of this article is to describe the injury patterns observed in the 2015 Philadelphia Amtrak train derailment. CONCLUSION: Fractures accounted for most observed injuries, but uncommon and potentially serious injuries included posterior sternoclavicular dislocation and mesenteric contusion. Imaging plays a critical role in the triage of patients during mass-casualty events, and familiarity with the injury patterns associated with high-velocity unrestrained blunt force trauma will aid diagnosis in any future similar occurrence.

RSNA Diagnosis Live: A Novel Web-based Audience Response Tool to Promote Evidence-based Learning.

Audience response systems have become more commonplace in radiology residency programs in the last 10 years, as a means to engage learners and promote improved learning and retention. A variety of systems are currently in use. RSNA Diagnosis Live™ provides unique features that are innovative, particularly for radiology resident education. One specific example is the ability to annotate questions with subspecialty tags, which allows resident performance to be tracked over time. In addition, deficiencies in learning can be monitored for each trainee and analytics can be provided, allowing documentation of resident performance improvement. Finally, automated feedback is given not only to the instructor, but also to the trainee. Online supplemental material is available for this article. © RSNA, 2017.

A Platform-Independent Plugin for Navigating Online Radiology Cases.

Software methods that enable navigation of radiology cases on various digital platforms differ between handheld devices and desktop computers. This has resulted in poor compatibility of online radiology teaching files across mobile smartphones, tablets, and desktop computers. A standardized, platform-independent, or "agnostic" approach for presenting online radiology content was produced in this work by leveraging modern hypertext markup language (HTML) and JavaScript web software technology. We describe the design and evaluation of this software, demonstrate its use across multiple viewing platforms, and make it publicly available as a model for future development efforts.
