Overview
An x-ray may be helpful in the diagnosis of intussusception. Plain x-ray abdomen of patient are done in supine and upright position. Findings on an x-ray suggestive of/diagnostic of intussusception include absence of air in right lower quadrant and right upper quadrant, soft tissue density in right upper quadrant in 25-60% of patients, and normal in 60% of cases.

- An x-ray may be helpful in the diagnosis of intussusception. Findings on an x-ray suggestive of/diagnostic of intussusception include:
- Normal in 60% of cases.
- Absence of air in right lower quadrant and right upper quadrant.
- Soft tissue density in right upper quadrant in 25-60% of patients.
- Distended loops of bowel with absence of colonic gas (sign of intestinal obstruction).
- Target sign
- Two concentric radiolucent circles superimposed on the right kidney.
- This signifies peritoneal fat around the intussusception.
- A study shows target sign is present in 26% of patients.[1]
- Crescent sign
- A soft tissue density projecting into the gas of the large bowel.
- Concealed liver margin.[2]
