We describe a systematic approach to the ultrasound US examination of the antropyloric region in children. US is the modality of choice for the diagnosis of hypertrophic pyloric stenosis HPS. The imaging features of the normal pylorus and the diagnostic findings in HPS are reviewed and illustrated in this pictorial essay. Common difficulties in performing the examination and tips to help overcome them will also be discussed.
