ACR Foundation

The mission of the ACR Foundation is to advance the profession and practice of radiology to benefit patients through specific emphasis on health policy research. The Foundation’s Board has set the focus of the Foundation’s efforts to advance health policy research in an effort to: 

  • Demonstrate the critical role that radiologists have in the era of team-based healthcare to best serve patients and society
  • Prioritize research opportunities to positively influence the policies that impact clinical care delivered to patients
  •  Develop empirical evidence that clarifies the role and value of radiology in evolving payment methodologies thus guiding policy makers and payers in allocating resources to the most valuable patient care services
  • Evaluate and demonstrate the important role that early detection of disease plays in population health management
