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.
