Anorectal malformation
Disease Information
Tests
How are anorectal malformations diagnosed?
Your baby's physician will perform a physical examination when your baby is born, and will look at the anus to see if it is open and in the proper position.
Diagnostic imaging tests may also be done to get more details on the severity of the malformation:
- Abdominal x-ray - A diagnostic test that uses invisible electromagnetic energy beams to produce images of internal tissues, bones and organs on film.
- Abdominal ultrasound (sonography) - A diagnostic imaging technique which uses high-frequency sound waves and a computer to create images of blood vessels, tissues, and organs. Ultrasounds are used to view internal organs as they function, and to assess blood flow through various vessels.
