Artificial Intelligence in Radiology: A Leadership Survey.

Purpose: Surveys to assess views about artificial intelligence (AI) of various diagnostic radiology constituencies have revealed interesting combinations of enthusiasm, caution, and implementation priorities. We surveyed academic radiology leaders about their views on AI and how they intend to approach AI implementation in their departments.

Materials And Methods: We conducted a web survey of Society of Chairs of Academic Radiology Departments (SCARD) members between October 5 and October 31, 2023 to solicit optimism or pessimism about AI, target use cases, planned implementation, and perceptions of their workforce.

The crescent sign on ocular ultrasound and correlation with elevated intracranial pressure: A prospective cohort study.

Objectives: While lumbar puncture (LP) remains gold standard for assessing intracranial pressure (ICP), LP can be difficult to perform and lead to complications. Noninvasive correlations for elevated ICP via ocular ultrasound (OUS) have shown mixed results. The primary objective of this study is to identify the frequency and test characteristics of the crescent sign on OUS for elevated ICP.

Real-time imaging reveals a role for macrophage protrusive motility in melanoma invasion.

Macrophages are primary cells of the innate immune system that mediate tumor progression. However, the motile behavior of macrophages and interactions with tumor cells are not well understood. Here, we exploit the optical transparency of larval zebrafish and perform real-time imaging of macrophage-melanoma interactions.

Urine Contamination Prevalence Using a Midstream Collection Device Compared with Clean Voided Collections in Dogs.

Collecting clean-caught voided urine samples is minimally invasive, but contamination occurs when urine passes through the nonsterile urethra and external genitalia. Discarding the initial urine stream may reduce these contaminants. This study hypothesized that using a midstream urine collection device would decrease bacterial and cellular contamination as compared with cleanly caught voided urine.

Effect of owner presence on healing of spontaneous chronic corneal epithelial defects after anterior stromal puncture.

Objective: To examine the effect of client presence on healing rates of spontaneous chronic corneal epithelial defect (SCCEDs) following debridement and anterior stromal puncture (ASP).

Animals Studied: Sixty-eight client-owned dogs.

Procedures: Dogs presenting prior to the COVID-19 shutdown were assigned to the C group (client in the room, 31/68), while dogs presenting after were assigned to group NC (no client in the room, 37/68).
