Are there any other useful radiologic studies for children with abdominal pain?
Ultrasound is an integral component of the workup for pyloric stenosis and for renal calculi and can be useful in evaluating the postpubertal female with possible ovarian or uterine disease, or the child with suspected appendicitis.
The CT scan is useful for detecting renal calculi and intra-abdominal infections, including appendicitis. However, it is important to remember that CT exposes children to a substantial amount of radiation. An upper gastrointestinal (GI) series with small bowel follow-through is used to detect intestinal malrotation.
Failure of the C-loop of the duodenum to cross the midline and an abnormal location of the cecum signify a malrotation is likely.
