Background: Image quality has a significant effect on the accuracy of radiographic diagnosis, and without optimal image quality many vital information might be missed and that will affect patient management negatively. This work is aimed at assessing the image quality of plain abdominal radiographs, which is one of the most frequent emergency radiographic examinations done, using the radiographic technical parameters and the guidelines of image quality criteria set by the European Commission (EC) as the measuring criteria for the development of quality assurance program. Materials and Methods: A prospective survey of anteroposterior erect and supine plain abdominal radiographs of adult patients produced at Ahmadu Bello University Teaching Hospital from August 2019 to October 2019 was conducted assessing its quality based on the radiographic technical parameters and the guideline set by the EC for assessing image quality using a data capture sheet. Results: Plain abdominal radiographs of 92 adults comprising, 55.4% male, 44.6% female, 42.4% erect, and 57.6% supine, were evaluated. The finding of the study revealed that image quality criteria on radiographic technical parameters were optimal in 2%, suboptimal in 50%, and poor in 48%. The image quality based on the EC guideline result shows that only 3% of the reviewed plain abdominal radiograph were optimum, 63.0% were suboptimal, and 34% were poor. Furthermore, the study proves that gender has no significant effect (P = 0.985) on the image quality based on radiographic technical parameter, whereas image quality based on the EC guideline is significantly influenced by gender (P = 0.023). Conclusion: The quality of plain abdominal radiographs produced at this center during this period was abysmal; hence, rigorous quality control programs, familiarization of the radiographers with the guidelines for assessing image quality, and total replacement of obsolete equipment need to be instituted.
