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.
