Paediatric bowel ultrasound in inflammatory bowel disease.

Ultrasound has long been favoured as first line when imaging children, primarily due to it being a non-invasive, relatively low cost, easily accessible modality. The many advantages of ultrasound evaluation in paediatric inflammatory bowel disease (IBD) vastly outweighs its limitations in both initial assessment and long term follow up. High frequency ultrasound provides excellent spatial resolution, and Doppler evaluation and compression sonography aids in providing real-time dynamic assessment in IBD where other modalities cannot. This paper outlines our ultrasound technique to maximise image quality and diagnostic accuracy, describes the imaging findings in paediatric IBD, and explores the advantages and limitations that ultrasound offers. We aim to illustrate to the reader that ultrasound is an invaluable imaging tool and should be the first line modality when imaging IBD in the paediatric patient. Crown
