Abstract

Pulsed fluoroscopy is considered a requisite for paediatric fluoroscopy. The goal of paediatric fluoroscopic studies is to produce interpretable images (to answer a specific question) at the lowest possible radiation exposure. Digital pulsed fluoroscopy has the advantage of reducing patient dose while yielding diagnostic images. The radiologist is responsible for choosing the appropriate pulse setting and deciding between storing the image as a 'picture-grab' or a true 'spot-film'. We present a simple description of this technology highlighting the advantages and disadvantages. We also describe in detail our recommended protocol for performing a micturating cystourethrogram and a barium swallow/meal in children.

Highlights

Fluoroscopy is most frequently used in the investigation of urinary tract infection! (micturating cystourethrography (MeUG)) and in screening those children suspected of gastro-oesophageal reflux
The radiologist has the advantage of screening a full swallow or bladder void and selecting the 'picturegrab' image from the series in retrospect
If we as radiologists get through the psychological barrier of 'ugly' images, we can certainly reduce the dose to our patients

Summary

Introduction

Fluoroscopy is most frequently used in the investigation of urinary tract infection! (micturating cystourethrography (MeUG)) and in screening those children suspected of gastro-oesophageal reflux (barium swallow/meal). Fluoroscopy is most frequently used in the investigation of urinary tract infection! (micturating cystourethrography (MeUG)) and in screening those children suspected of gastro-oesophageal reflux (barium swallow/meal). Paediatric radiology is especially concerned with minimising radiation dose because of the higher risk of radiogenic cancers in children due to medical irradiation." The goal of fluoroscopic studies is to produce interpretable images at the lowest possible radiation exposure and dosage to the patient."
