- First-line investigation for the evaluation of bowel and urological disease.
Indications for suspected
- Large and Small bowel obstruction (including volvulus)
- Perforation of an abdominal viscus

- Ureteric calculi
- Foreign bodies.
Different types of AXR
- Supine anterior-posterior (supine AP): common and is the widespread standard approach with the patient lying on their back.
- Erect AXR: patient stands or sits up, allowing for the observation of air-fluid levels in the bowel
- Decubitus: lies on one side with the beam passing through horizontally, providing an AP view.
