Hypertrophic Pyloric Stenosis Mr Findings

Infantile hypertrophic pyloric stenosis (IHPS) is a condition affecting young infants, in which the antropyloric portion of the stomach becomes abnormally thickened and manifests as obstruction to gastric emptying. The clinical diagnosis hinges on palpation of the thickened pylorus, or 'olive.' Abdominal palpation is accurate but not always successful, in such cases, radiologic examinations including US or MRI can be performed. US is the first choice of imaging modality. Unfortunately, in case of difficulty by the sonographic diagnosis of IHPS such as overlying bowel gas, MRI could be useful for the diagnosis
