Abstract

All medical and healthcare practitioners have a duty of care to their patients. As part of this duty of care, practitioners are required to give sufficient information about all aspects of the examination, including the risks involved. It is the responsibility of the radiographer performing CTC examinations, therefore, to ensure that patients have been provided with the necessary information, including related risks, to enable informed consent to be established. Radiographers must work within the scope of their practice and the expectations set by the professional and regulatory bodies of the country in which they practise.
