UK are also taking on roles that were typically only undertaken by the Radiologist (a medical doctor who specialized in interpreting X-rays), Urologist or Cardiologist in the past. This extended practice includes various interventional procedures not excluding barium enemas, barium meals/swallows, peripheral angioplasties, nerve root injections, central line insertions and many other procedures. The professional body and workers union for Radiographers in the United Kingdom is the Society and College of Radiographers (SCoR). The union has been heavily involved in extending practice of Radiographers in the United Kingdom and has helped expand the role of the Radiographer greatly. Expanded practice Radiographers are now able to write reports and diagnose pathologies and/or conditions seen on differing diagnostic media after completing a HCPC and SCoR accredited university course; completing a course in this modality allows the Radiographer to become a reporting Radiographer in their chosen specialty. Diagnostic Radiographers are able to become supplementary prescribers which allows them the capacity to prescribe medications in partnership with an independent prescriber (a doctor or a dentist); the supplementary prescriber is to implement an agreed Clinical Management Plan for an individual patient with that patient's agreement. An accredited university course must be undertaken before this role extension is annotated onto a HCPC registrant's record. It is thought that in the future Diagnostic Radiographers in will gain independent prescribing rights, however this is currently limited by their restricted and varied scope of practice. In 2016, the introduction of independent prescribing right was agreed for Therapeutic Radiographers after a consultation by the Medicines and Healthcare products Regulatory Agency (MHRA) United States In the United States, these professionals are known as . Formal training programs in radiography range in length that leads to a certificate, an associate, or a bachelor's degree. The American Registry of Radiologic Technologists (ARRT), the primary credentialing organization for Radiologic Technologists in the United States, requires that candidates for ARRT Certification Exams must have an associate degree at minimum as of January, 2015, effectively ending non-degree granting diploma programs. Accreditation is primarily through The Joint Review Committee on Education in Radiologic Technology (JRCERT), the only agency recognized by the United States Department of Education and the Council for Higher Education Accreditation to grant accreditation to both traditional and online programs in Radiography, Radiation Therapy, Magnetic Resonance Imaging, and Medical Dosimetry. An online page where prospective students can check the accreditation of programs is maintained by
