| Summary: | Assessing the repeat rate is crucial to reduce unnecessary dose to the patient by identifying the major
cause for repeating the x-rays exposure to the patient and apply corrective measures. To analyse the
repeat rate of routine lower limb projections in direct digital radiography (DR) from general radiology
department of Pantai Klang Hospital. 26 months retrospective repeated radiograph was acquired from
Picture Archiving and Communication System (PACS) at Hospital Pantai Klang. The retrieved
radiographs were grouped based on the reason for the i radiographs being rejected which are incorrect
positioning, incorrect collimation, patient movement, incorrect exposure factors, artefact, and other
reasons. Total repeated radiographs retrieved for basic lower limbs projections were 13616. Knee was
the highest repeted examination and the lowest repeat rate was tibia fibula. (repeat rate: knee = 1.04%,
tibia fibula = 0.57%). incorrect positioning is the major causes for repeat exposure for all examinations
type, followed by incorrect collimation, other categories, centring ray error, incorrect exposure factors
and artifact. |
