Traffic Light: An Alternative Approach to Abnormality Signalling

'Red dot' is the most common form of abnormality detec�on system in clinical prac�ce. The SCoR 2013 policy recommends replacement with preliminary clinical evalua�on (PCE) however this requires a different skill set and radiographers are arguably not yet ready for this change. Wright (2013) iden�fied the need to be able to make accurate decisions before processing to wri�ng commentary. The 'traffic light' system poten�ally bridges this gap as it requires radiographers to make a decision on all the images they take. The op�on to provide a preliminary clinical evalua�on (PCE) is an addi�on feature which again scaffolds the radiographers towards the wider goal.
