When an X-ray Is Needed
The X-ray is often requested because it is quick, widely available, and relatively inexpensive. However, not every complaint needs an X-ray, and the decision is best made together with your doctor.
Situations that often need an X-ray
An X-ray is usually requested for suspected fractures after a fall or impact, a prolonged cough or fever suspected to be pneumonia, and certain abdominal pain suspected to be a bowel obstruction. It is also often used to check the position of medical devices.
In children, an X-ray may be requested when a swallowed foreign object or a growth plate injury is suspected.
Situations that do not always need one
Mild back pain without warning signs usually does not require an X-ray right away. Many guidelines recommend conservative treatment before imaging, unless red flags are present.
Ordinary headaches generally do not need a skull X-ray. Clinical assessment by a doctor is often more important than an image.
Warning signs that need prompt attention
Seek care promptly for severe pain after an injury, a body part that looks deformed or cannot be moved, or shortness of breath, chest pain, or high fever with weakness.
Your doctor will decide whether an X-ray is needed. Do not delay care just because you are unsure whether an X-ray is necessary.
