Abstract
Objective: To determine the common factors that affect the diagnostic quality of radiographs in radiodiagnostic centers in Lagos state, Nigeria.
Methods: Self-administered questionnaires containing both open and close-ended questions were distributed to the supervising radiographers in radiodiagnostic centers within the Lagos metropolis. The questions asked included the film/reject ratio in each center and reasons why each film was rejected.
Results: Faulty x-ray machines, movement on the part of the patient, poor darkroom film processing, and suboptimal radiographic techniques were the main reasons respondents identified as factors commonly responsible for the production of faulty films. In some cases, more than one of these factors was responsible.
Conclusion: There is a need to routinely ensure that x-ray machines are properly calibrated in order to reduce the rate of film rejects in our x-ray facilities. In addition, equipment that is old and cannot be properly calibrated should be replaced. This would guarantee optimum performance and reduce radiation dose to patients and personnel. Younger radiographers should also be open to mentoring by older colleagues so they can acquire useful tips on how to reduce the production of films with unacceptable diagnostic quality.
They should be encouraged to attend continuing education programs for improved expertise. Also, quality control and maintenance programs such as the reject film analysis or regular equipment maintenance should be enforced in radiodiagnostic centers.
