Traffic Light: An Alternative Approach to Abnormality Signalling

'Red dot' is the most common form of abnormality detection system in clinical practice. The SCoR 2013 policy recommends replacement with preliminary clinical evaluation (PCE) however this requires a different skill set and radiographers
are arguably not yet ready for this change. Wright (2013) identified the need to be able to make accurate decisions before processing to writing commentary.
The 'traffic light' system potentially bridges this gap as it requires radiographers to make a decision on all the images they take. The option to provide a preliminary clinical evaluation (PCE) is an addition feature which again scaffolds the radiographers towards the wider goal.
