In an official statement published on their website, the American College of Radiology (ACR) declared their opposition to the change in title from physician assistant (PA) to physician associate.
They wrote "The physician assistant title accurately reflects the training of these professionals and their role in any physician-led team. Any change would lead to confusion among patients as they make important healthcare choices."
The ACR argues that radiologists are uniquely trained and qualified to provide radiologic care, and they oppose supervision or interpretation of radiological exams or procedures by non-physician providers.
The role and training of Registered Radiology Assistants (RRA), a position which does not include imaging supervision or interpretation, is endorsed by the ACR.
