Abstract:
:The three missions of academic radiology compete with one another for time and funding. Revenue for the clinical mission often subsidizes education and research. Given the internal and external drivers/pressures on health care and, more particularly, on academic health centers, the current model is unsustainable. Trends seen in other industries are entering academic health care. The radiology department of the future will need to be more efficient with increasingly fewer resources while meeting its missions at higher levels of expectation.
