July 19, 2017 — The American College of Radiology (ACR) recently collaborated with professional medical societies to update guidance to promote safe and effective diagnostic and therapeutic radiology use.
The ACR and the American Society for Radiation Oncology (ASTRO) revised the ACR–ASTRO Practice Parameter for the Performance of Total Body Irradiation.
The ACR and the American Association of Physicists in Medicine (AAPM) updated the ACR–AAPM Technical Standard for Diagnostic Medical Physics Performance Monitoring of Computed Tomography (CT) Equipment.
“The ACR-ASTRO parameter improves care quality with specific training and technique guidance,” said Alan C. Hartford, M.D., Ph.D., FACR, chair of the ACR Committee on Practice Parameters — Radiation Oncology.
“We provide a baseline of technical and equipment performance standards that are designed to maintain high-quality care,” noted Maxwell R. Amurao, Ph.D., MBA, chair of the ACR Committee on Practice Parameters and Technical Standards — Medical Physics.
Both documents were approved by the ACR Council Steering Committee and the Board of Chancellors. They are available now and take effect Aug. 1.
All ACR Practice Parameters and Technical Standards are available at no charge on the ACR website.
