Abstract

Abnormality detection by radiographers is seen as a potential for role development of radiographers, especially in specialised areas of radiography such as MRI.

This research study was designed to evaluate the capabilities of radiographers in the detection of abnormalities from MRI images of the brain.

A research tool in the form of a checklist questionnaire was formulated together with a set of MRI images from which quantifiable data was obtained. These were constructed with the help of radiologists. A pilot study was performed on a sample of two radiographers, after which only minor alterations were required. The checklist questionnaire was then distributed among the population to elicit the information required.

The results of the study demonstrate that although radiographers are willing to develop and extend their role through abnormality detection, at this point in time their accuracy in detecting and describing abnormalities is below acceptable standards in radiology.

On the basis of these findings, recommendations are proposed for the implementation of training programmes, which include both theoretical and practical components. Further studies are recommended for the evaluation of such training so that radiographers may be in a position to undertake abnormality detection within their current role,
