Curricula for Teaching MRI Safety, and MRI and CT Contrast Safety to Residents: How Effective Are Live Lectures and Online Modules?

Purpose: The advent of the diagnostic radiology core examination and the new ACGME "milestone" evaluation system for radiology residents places new emphasis on topics in MRI and CT safety, and MRI and CT contrast agents. We evaluated whether either lecture-based teaching or online modules would improve baseline resident knowledge in these areas, and assessed which intervention was more effective.

Methods: Before didactic intervention, 2 cohorts were created from 57 radiology residents, with equal numbers and a matched level of training.

The expression patterns of minor fibrillar collagens during development in zebrafish.

Minor fibrillar collagens are recognized as the organizers and nucleators during collagen fibrillogenesis but likely serve additional functions. The minor fibrillar collagens include collagens type V and XI. Mutations of collagens type V and XI can cause Ehlers-Danlos, Stickler's, and Marshall's syndromes in human.
