The aim of this study was to examine recent shifts in place of service for noninvasive diagnostic imaging (NDI) and determine whether hospitals have lost business to private outpatient imaging facilities. ⋯ Medicare NDI utilization rates increased in all places of service between 1996 and 2006. Growth in hospital outpatient imaging was slower than that in private imaging facilities. Because NDI can be a profitable business, it seems that hospitals have lost an important opportunity. Much of this loss of business was to nonradiologist physicians, whose private office imaging utilization rate grew considerably more rapidly than that of radiologists.

Corporate scientific activity lies at the heart of the modern academic institution, and yet field-specific estimates of institutional or departmental scholarly productivity are difficult to assess. The authors sought to estimate long-term and current departmental research efforts at residency-sponsoring US radiation oncology departments, using modifications of established bibliometric indices. ⋯ The use of quantitative metrics provides departments and researchers with a mechanism to evaluate collective scientific productivity and serves as an impetus for improved performance across the field.
