Abstract:
:The association of GE Medical Systems and the AUR represents a unique collaboration between academic radiology and industry that bears important potential for elevating the quality of clinical research in radiology and developing a cadre of high-quality radiologist researchers for the future. The establishment of the GERRAF is especially timely given the new imperatives of the rapidly changing health care environment, with its emphasis on expenditure reduction. The ultimate goals of GERRAF are to develop research leaders for radiology that will provide guidance for appropriate clinical practice, better train future researchers, and secure the role of radiologists in caring for patients.
