Role development and extension for radiographers in computed tomography: Literature review findings and their application to Zimbabwe.

Computed Tomography (CT) technology has evolved into avital diagnostic tool in modern medical practice, leading to the development and extension of the CT radiographer's role. While some countries have made progress in developing and extending radiographers' roles in CT, resourceconstrained settings like Zimbabwe have been slower to implement these changes. The purpose of this review is to inform role changes for radiographers in Zimbabwe and similar settings by reviewing the literature on role development and extension for radiographers in CT. The review explores the concepts of role development and extension, emphasizing the necessity for changes in radiographers' roles in CT due to factors such as radiologistsshortages, cost containment, quality improvement needs, and technological advancements. It also addresses the opposition to role development and extension, emphasizing the fundamentalimpetus for these changes should be to provide high-quality and effective patient-centered care. The paper delves into specific areas of role development and extension for radiographers in CT, including intravenous (IV) cannulation and contrast media administration, performing CT colonoscopy examinations, reporting on CT brains, and the significance of research and clinical audit in CT. It underscores the potential benefits of these expanded roles, such as improved patient care, workflow efficiency, and the workload of radiologists, as well as advancements in education, service delivery, and technological innovations. The review underscores the need for further research to ensure evidencebased implementation of role development and extension for radiographers in CT. Embracing these changes and providing the necessary support and training can lead to improved patient care, address skill shortages, and advance the radiography profession in resource-constrained settings like Zimbabwe.
