Paediatric pelvic imaging: optimisation of dose and technique using digital grid-controlled pulsed fluoroscopy

Abstract

Fluoroscopy acquired images are now used since the fluoroscopic techniques give much less dose than conventional radiography and provide images of sufficient quality for clinical assessment. Indeed, as there was no significant difference in clinical usefulness between the frame grab and DSI techniques, it is planned to use frame grab alone, thus gaining additional dose saving.

“…Pre-operative radiographs were analysed, and neck shaft angle and Reimer's migration percentage were recorded [24]. Hard copy fluoroscopy was used for follow-up rather than conventional radiographs because the radiation exposure is greatly reduced [25, 26].…”

Pediatric radiation protection

“…The quality assurance program should also perform regular tests to all machinery involved with the delivery of radiation burden, and should organize audits to ensure that DRL are kept regarding diagnostic tests in pediatrics as well as in all imaging procedures involving radiation exposure. All departments can benefit from audits and re-evaluation and standardization of their procedures [28,50,51,52,53].…”

“…Pulsed fluoroscopy provides increased resolution for moving as well as stationary objects [58]. In many centers, fluoroscopically acquired digitized images have replaced hard copy images on certain clinical indications, such as follow-up of Perthe's disease or micturating cystograms, with significant dose-reduction [47,50,56]. Regarding complex examinations, there are differences among centers in the number of spot-film images and fluoroscopy time per test [59].…”
