Repeat Reject Analysis

      The frequency of diagnostics using ionising radiation is on the increase with the potential for patients to attend radiology multiple times over their lifetime. Optimisation in radiology means striking the right balance between image quality and patient radiation exposure; it is both multi-disciplinary and multi-factorial. Reject and repeat rate analysis (RRA) is a quality indicator in Radiology and supports the department in optimising images in general x-ray. There is a special RRA tool on the GE Discovery 656 X-ray system that aids the team in both recording and analysing rejects and repeated images. AAPM TG151 recommends that 8% be used as a target for overall rejected image rate, and 10% as a threshold for investigation and possible corrective action.
