Objective: To determine the level of improvement of reject rate, persistent main cause of repeated films and re-occurring most common projection(s). Methodology: A prospective design was carried out on radiographs of poor image quality collected from the 3 conventional diagnostic rooms for a period of 9 months (April – December, 2011) at the Radiology department, University of Maiduguri Teaching Hospital. All radiographs with good diagnostic image quality, those used for contrast study and mammograms formed the exclusion criteria. Result: The reject rate was found to be 29.34%, Chest radiograph has the highest reject (12.19%), over and under exposure contributed to about 24.28% and 36.2% respectively. Anatomical cutoff ranked the next (21.91%) and motional blur (0.14%) the least. Conclusion: The study has outlined reasons why radiographs were rejected and the rejected rate for the period of study to be 29.34% which is almost 5x greater than the recommendation given by World Health Organization (WHO) on radiation protection, Conference of Radiation Control Program Directors, (CRCPD) and Quality assurance for Radiographers and Radiological Technologist, this calls for immediate rectification strategies like knowledge update, repairs and frequent quality assurance measures in place.
