Last fluoroscopy hold in paediatric fluoroscopy: dynamic capture of physiological events and a potential for radiation exposure time reduction.

The purpose of this study was to retrospectively evaluate last fluoroscopy hold (LFH) in paediatric fluoroscopy. LFH is a software program that enables dynamic storage of last fluoroscopy sequences. A hundred and ninety-four paediatric patients underwent 215 fluoroscopy examinations during a 14-month period. LFH was employed to review an equivocal finding, when last image hold did not provide an adequate diagnostic image or when a physiologic dynamic event was too fast or did not last long enough to capture. LFH was used in 29% of the examinations. The Institutional Review Board approved this study and waived informed consent.
