Like many health-care related fields, the area of diagnostic radiology is growing rapidly, and a number of educational institutions and professional organizations have been working on creating online resources to help those entering the field. The Department of Diagnostic Radiology at Yale University has created this resource, which functions as a thorough listing of web-based materials. Upon arriving at the site, visitors can scroll through a list of thematic materials, including radiology sites, departmental resources, and teaching file and image sites. Educators working in the field will find the teaching file sites particularly useful, as they include links to materials that can be used in the classroom. Additionally, educators may want to give this site to their students, as they can also make good use of it.
