The COVID-19 pandemic and subsequent policies (e.g., social distancing, travel restrictions) challenged both organizers for and attendees of programs typically held in person. Many scientific training programs quickly adapted to virtual formats by incorporating digital assets developed for virtual learning and remote social engagement. At the…

We follow a radioactive sample from production in a reactor to its use in a biological application to model the complexities in the use of radioactive isotopes from a student's perspective. Specifically, we describe a way to use gamma ray detection outside the body to estimate the clearance rate of these radioisotopes from the body and how that…

Self-monitoring is essential for effectively regulating learning, but difficult in visual diagnostic tasks such as radiograph interpretation. Eye-tracking technology can visualize viewing behavior in gaze displays, thereby providing information about visual search and decision-making. We hypothesized that individually adaptive gaze-display…

Diagnostic errors are a major, largely preventable, patient safety concern. Error interventions cannot feasibly be implemented for every patient that is seen. To identify cases at high risk of error, clinicians should have a good calibration between their perceived and actual accuracy. This experiment studied the impact of feedback on medical…

Visuospatial ability plays a crucial role in anatomy related study success as studies have shown that students with high scores on a mental rotation test (MRT) perform better on anatomy exams. We hypothesized that segmenting anatomical structures on radiological images might impact students' visuospatial abilities as measured by MRT scores.…

The carbonyl group of an aldehyde or ketone reacts with different types of nucleophiles through a nucleophilic addition reaction. When the nucleophile is water, the product obtained is a "gem"-diol or geminal diol. This functionalization is unstable and quickly reverts to the parent carbonyl group. The chemistry of "gem"-diols…

People miss a high proportion of targets that only appear rarely. This low prevalence (LP) effect has implications for applied search tasks such as the clinical reading of mammograms. Computer aided detection (CAD) has been used to help radiologists search mammograms by highlighting areas likely to contain a cancer. Previous research has found a…

For over 50 years, the satisfaction of search effect has been studied within the field of radiology. Defined as a decrease in detection rates for a subsequent target when an initial target is found within the image, these multiple target errors are known to underlie errors of omission (e.g., a radiologist is more likely to miss an abnormality if…

Simulation has an ever-increasing role in health professions' education, however there is limited evidence on the transferability of learning to practice. In this study, a pragmatic approach using a convergent mixed methods design explored the use of a virtual high-fidelity Computed Tomography (CT) simulator in preparing students for clinical…

Basic competency in radiological imaging is essential for physicians to identify and manage diseases. An optimal place in which to include imaging in the medical curriculum is during anatomy as students can correlate the 3D anatomy from their body donors with the 2D cross-sectional anatomy. The goal of this project was to enhance first-year…

For the past seven years, we -- a museum educator and an academic radiologist -- have co-taught Seeing in Art and Medical Imaging, a first-of-its-kind medical humanities curriculum for residents in nuclear medicine and radiology based at the Harvard Art Museums. The program aims to foster residents' close looking and clinical skills,…

Despite numerous investigations of the prevalence effect on medical image perception, little research has been done to examine the effect of expertise, and its possible interaction with prevalence. In this study, medical practitioners were instructed to detect the presence of hip fracture in 50 X-ray images with either high prevalence (N[subscript…

Recent work has shown that perceptual training can be used to improve the performance of novices in real-world visual classification tasks with medical images, but it is unclear which perceptual training methods are the most effective, especially for difficult medical image discrimination tasks. We investigated several different perceptual…

The Beatles formed in Liverpool are one of the most famous music groups in the history of pop considered as the best-selling artists in the category "band," with the highest amount of claimed record sales. With their foremost pioneering activities in songwriting, artistic presentation, and recording, the band revolutionized many aspects…

High-fidelity anatomical models can be produced with three-dimensional (3D) scanning techniques and as such be digitally preserved, archived, and subsequently rendered through various media. Here, a novel methodology--digital body preservation--is presented for combining and matching scan geometry with radiographic imaging. The technique…
