Purpose: To identify the characteristics of and the motives behind radiologists use, or lack thereof, of after-hours services. Methods: From August 2005 to June 2006, 300 non-specialty hospitals randomly selected from the 2005 American Hospital Association Directory of Hospitals were contacted by phone, email, and mail, with an attempt made to speak to the chief of radiology. We obtained 115 responses, a 38.3% response rate, including 64 from practices that used an external after-hours service. Responses were analyzed using descriptive statistical analyses.

The purpose of this study was to determine whether radiologists could accurately assess osteopenia on chest plain films. Two chest radiologists evaluated lateral chest films from 100 patients (80 female and 20 male), ranging in age from 16 to 86 years, for osteopenia and its associated findings. Intra- and interobserver agreement was determined using weighted kappa statistics, and accuracy was assessed by making comparisons to bone mineral density as measured by the non-invasive gold standard of dual-energy x-ray absorptiometry (DXA). Overall, radiologists were good at identifying signs of late, but not early, disease. Intraobserver consistency was substantial for fish vertebrae …
