Technique of pediatric thoracic CT angiography.

CT angiography is now an accepted application of contemporary multidetector row CT. Faster scanning, thinner slices, and improvement in intravenous contrast enhancement are benefits that have offered unique opportunities for pediatric thoracic angiographic evaluation, and often obviate routine angiography. Pediatric CT angiography can be challenging but adherence to a relatively straightforward step-by-step method, emphasizing patient preparation and technical familiarity, can result in excellent examinations even in the smallest infants and most complex clinical scenarios.
