Radiologic Technologists: Roles, Training, and Scope of Practice

Radiologic technologists (also called radiographers) are nationally certified, state-licensed healthcare professionals who perform diagnostic imaging examinations. They are not physicians; they operate under the direction of a radiologist.

Core Responsibilities

• Position patients and select optimal imaging parameters (kVp, mAs, collimation) for X-ray, CT, fluoroscopy, and mobile radiography.
• Apply radiation safety principles (ALARA): shielding, distance, time, and dose monitoring.
• Verify patient identity, procedure, and pregnancy status; obtain informed consent when required.
• Operate and troubleshoot imaging equipment; perform quality control tests.
• Administer contrast media (under protocol) and monitor for reactions.
• Collaborate with radiologists, nurses, and referring physicians to ensure diagnostic image quality.

Education & Credentials

• Associate or bachelor’s degree from a JRCERT-accredited program.
• ARRT certification (primary credential) in Radiography (R); additional certifications for CT, MRI, Mammography, etc.
• State licensure required in most states.
• Continuing education (24 CE credits biennially) to maintain certification.

Work Settings

Hospitals, outpatient imaging centers, orthopedic clinics, urgent care, mobile imaging services, and dental offices (for CBCT/panoramic).

Radiographers are the hands-on experts who acquire the images radiologists interpret—essential partners in diagnostic accuracy and patient safety.
