radiologic technologists; radiologist assistants
HB 2050 updates Arizona's regulations for medical imaging professionals. It sets specific education standards for radiologic technology schools (24 months, 400 classroom hours, 1,865 clinical hours), establishes exam content covering radiation safety and imaging techniques, and creates new certification for bone densitometry technicians. The bill formally defines "radiologist assistants" as a distinct role requiring department certification, allowing them to perform specific procedures under a radiologist's supervision (like fluoroscopy and administering contrast) but prohibiting image interpretation or diagnosis. It also mandates continuing education requirements ranging from 2 to 50 hours every two years, depending on certification type. This directly affects radiologic technologists, radiologist assistants, bone densitometry technicians, and nuclear medicine technologists in Arizona.
