不要再濫用 KUB...

Abdominal x rays - rarely useful
Is there ever a reason to request an abdominal x ray (AXR)?

Hardly ever, according to this review of evidence for their use in emergency departments. An AXR gives a radiation dose equivalent to that from 35 chest x rays and no longer has a place in the routine investigation of abdominal pain.

Evidence based reasons for requesting an urgent AXR include
  • Acute abdominal pain, if bowel obstruction is suspected
  • Esophageal foreign body is suspected
  • Sharp or poisonous foreign body is suspected.
