Answer

In cases of intussusception, ultrasonography may be used as the initial diagnostic study to avoid a more invasive barium or pneumatic enema. The ultrasonographic finding of a "target" sign or a "pseudokidney" sign is highly suggestive for intussusception. Because ultrasonographic studies are only diagnostic, many clinicians choose to proceed directly to barium, saline, or pneumatic enema, which are both diagnostic and potentially therapeutic.

In patients with gangrenous bowel, upper and lower contrast studies aid in diagnosis.
