The ACR awards accreditation to facilities for the achievement of high practice standards after a peer-review evaluation of its practice. Image quality and procedure evaluations are conducted by board-certified radiologists and medical physicists who are experts in the field. The program also evaluates personnel qualifications, adequacy of facility equipment, quality control procedures and quality assurance programs. All findings are reported to the practice via a comprehensive report that includes recommendations for improvement. The ACR accredits facilities in: Magnetic resonance imaging (MRI), breast ultrasound, computed tomography (CT), mammography, nuclear medicine, positron emission tomography (PET), stereotactic breast biopsy, ultrasound, and radiation oncology.
