to and participate in continuing professional development Enforcement of radiation protection (There is a duty of care to patients, colleagues and any lay persons that may be irradiated.) Justification of radiographic examinations Patient care Production of diagnostic media Safe, efficient and correct use of diagnostic equipment Supervise students and assistants On a basic level, radiographers do not generally interpret diagnostic media, rather they evaluate media and make a decision about its diagnostic effectiveness. In order to make this evaluation radiographers must have a comprehensive but not necessarily exhaustive knowledge of pathology and radiographic appearances; it is for this reason that radiographers often do not interpret or diagnose without further training. Notwithstanding, it is now becoming more common that radiographers have an extended and expanded clinical role, this includes a role in initial radiological diagnosis, diagnosis consultation and what subsequent investigations to conduct. It is not uncommon for radiographers to now conduct procedures which would have previously been undertaken by a cardiologist, urologist, radiologist or oncologist autonomously. Contrary to what could be inferred, radiographers conduct and contribute to investigations which are not necessarily radiological in nature, e.g. sonography and magnetic resonance imaging. Radiographers often have opportunities to enter military service due to their role in healthcare. As with most other occupations in the medical field many radiographers have rotating shifts that include night duties. Career pathways Radiography is a deeply diverse profession with many different modalities and specialties. It is not uncommon for radiographers to be specialized in more than one modality and even have expertise of interventional procedures themselves; however this depends on the country in which they operate. As a result of this the typical career pathway for a radiographer is hard to summarize. Upon qualifying it is common for radiographers to focus solely on plain film radiography before specializing in any one chosen modality. After a number of years in the profession, non-imaging based roles often become open and radiographers may then move into these positions. Imaging modalities Generally, imaging modalities are all diagnostic, all have the potential to be used therapeutically in order to deliver an intervention.
