European Society of Paediatric Radiology Abdominal Imaging Task Force recommendations in paediatric uroradiology, part X: how to perform paediatric gastrointestinal ultrasonography, use gadolinium as a contrast agent in children, follow up paediatric testicular microlithiasis, and an update on paediatric contrast-enhanced ultrasound.

At the European Society of Paediatric Radiology (ESPR) annual meeting 2017 in Davos, Switzerland, the ESPR Abdominal (gastrointestinal and genitourinary) Imaging Task Force set out to complete the suggestions for paediatric abdominal imaging and its procedural recommendations. Some final topics were addressed including how to perform paediatric gastrointestinal ultrasonography. Based on the recent approval of ultrasound (US) contrast agents for paediatric use, important aspects of paediatric contrast-enhanced US were revisited. Additionally, the recent developments concerning the use and possible brain deposition of gadolinium as a magnetic resonance imaging contrast agent were presented. The recommendations for paediatric use were reissued after considering all available evidence. Recent insights on the incidence of neoplastic lesions in children with testicular microlithiasis were discussed and led to a slightly altered recommendation.
