Background: Analysis of rejected radiographs is an important quality indicator of any radiology department. At King Abdulaziz Medical City (KAMC), about 185,000 radiographs are performed annually. Methods: The rejected radiographs over a period of 5 years were analyzed using a dedicated electronic rejection system. The rejection is performed by a certified radiologist and communicated electronically to the concerned technologist. Results: A total of 455 rejected radiographs were reviewed and analyzed. Of the reviewed rejected radiographs, 247 were adults (60%) whereas 166 were pediatrics (40%). In terms of sex, 231 (56%) of the rejected radiographs were for men and 182 (44%) were for women. The most common reason for rejection was labeling (22%), followed by procedure protocol (20%). Other reasons included positioning (14%), processing (14%), artifacts (13%), wrong documentation (9%), and exposure error (6%). The rejection due to exposure error was very low (6%) owing to the utilization of digital systems that offer a wide exposure latitude. Reported data at hospitals that use analog systems show up to 67% of rejections were due to exposure error. In terms of body parts, the highest rejection was for extremities (43%) followed by chest (31%). The remaining rejected radiographs includes abdomen (9%), spine (8%), pelvis (5%), and head and neck (4%).Conclusion: The outcome of this study can be used to set up training programs to improve radiological services and reduce the unnecessary radiation exposure to the patients.
