“…In our study, the reject rate in chest and extremities radiographs were due to exposure (mAs) factors and were calculated to be 94% and 87% respectively. Similar results were found by Zewdeneh D et al 3 who concluded that highest reject rate is for chest (27.5%) and main reason of reject was overexposure (22.8%) whereas Dunn MA et al 4 found positioning as the main cause for reject of the chest radiograph in their study. Both over exposure and underexposure were seen attributed to the performance of the X-ray machines, technical skill and training.…”

“…Previous studies 3 reported the highest rate in chest xrays (27.5%) followed by skull radiographs (25.6%). Dunn MA et al 4 found approximately 50% of all plain radiographic examination were chest X-rays and had a highest reject rate of 6.5%.…”

“…Out of the 15388 radiographs exposed 3404 radiographs were rejected due to one or multiple factors accounting for a reject rate of 22.12%. Zewdeneh D et al 3 reported reject rate of 4.94% for public hospitals and 0.83% for private hospital which was below the WHO criteria of 5%. 1 Hence reject rate in our study is higher than Zewdeneh D et al 3 The main reason of discrepancy can be multifactorial like use of old machines, with frequent problem of calibration and collimation, faulty technique used by radiographers due to inattentiveness, excessive workload and not so favorable working environmental conditions can also be accountable for the increased reject rate.…”

This further adds various patients' factors like movement, not able to hold breath and non-compliance of instructions by patients were responsible for the rejection of the xray films.…”

Quality assurance in diagnostic radiology is of paramount importance to provide quality services leading to better diagnostic yield and thus accurate and timely treatment. Reject analysis study was done in conventional radiography to find out the incidence and the causative factors so that necessary steps be taken to avoid these factors resulting in less repetition of films thus reducing cost and unnecessary radiation to patients and personnel working in radiology department.

“…Thus, the objective of reject/repeat analyses is identifying ways to minimize patient exposure and reduce costs. Diagnostic radiology departments would be able to identify potential problem areas, scrutinize the reasons for these problems and come up with ways to rectify them [11].…”

Medical diagnostic X-rays are the largest manmade source of ionizing radiation received by the members of the general public. The aim of this study was to evaluate the radiographic reject/repeat rate and also to determine dose to the patients from radiographic rejects/repeats in radiology centers of Urmia University of Medical Sciences. During a 4 month period the most frequently examinations were chosen in three radiology centers. A form was designed as a reject/repeat analysis form for radiographers to complete each time a film was rejected by radiologists or repeated. The collected data were compiled at the end of each week and entered into a computer for analysis at the end of study. The results of this study showed that highest and lowest repetition rates were for pelvis, 14.01% and upper limb, 4.17%, respectively. The main reasons of repetition of radiographs were due to exposure (54%) and positioning (18%) errors. The average repeat rate in all three hospitals was 7.20%. It was found that human error has important role to repetition of radiographs. It is demonstrated that those patients having repeated radiographs received an average of 3.23 Gy·cm<sup>2</sup>. Based on the findings of this study it must be remembered that the highest repetition rate was for pelvis. Considering the radiosensitive organs related to pelvis especially in pediatric patients some special considerations must be applied for pelvis examinations
