How is whiplash diagnosed?
Whiplash is an injury of the muscle and soft tissue in your neck that can't be seen by x-ray. Whiplash is usually a diagnosis of exclusion, meaning once other injuries have been ruled out, your doctor may feel that the only explanation for your pain and symptoms is whiplash.

In order to rule out other injuries, your doctor could order more specialized tests than x-rays, such as magnetic resonance imaging (MRI) or computed tomography scan (CT). These are more specific than x-rays and allow your doctor to look at the body tissue more closely.
