CT scans after an accident

In plain English: a CT (computed tomography) scan uses a series of X-rays and a computer to build cross-section images of your body. It's fast, which is why emergency departments rely on it after crashes and falls.

What a CT scan is good at

  • Bleeding in or around the brain, and skull fractures after a head injury.
  • Fractures, especially complex breaks in the spine, pelvis and face that plain X-rays can miss.
  • Internal injuries to organs such as the liver, spleen and kidneys.
  • Chest injuries, including collapsed lungs and rib fractures.

A CT can be done in minutes, which matters when doctors need to decide quickly whether you need surgery.

What it often misses

CT is less sensitive to soft tissue. Ligament and tendon tears, disc injuries, nerve damage and many concussions don't show up well, or at all. An MRI is usually better for these, but it's slower and not always done in the emergency room.

This matters for your claim. A report that reads "no acute findings" means the scan didn't show a fracture, bleed or organ injury. It doesn't mean you have no injury. Insurers sometimes quote a normal CT as if it settles the question. It doesn't, and your doctors can explain why in writing.

Example

After a rear-end crash, a driver's neck CT is clear of fractures. Months later, with arm tingling and neck pain that won't go, an MRI shows a disc herniation pressing on a nerve. The early CT helps his claim, because it shows no fracture and points to the disc injury as the source.

How CT results are used in a claim

  1. Proving the injury. A fracture or bleed on CT is strong, objective evidence.
  2. Timing. A scan on the day of the accident ties the injury to the event.
  3. Pre-existing conditions. Radiologists often note degenerative changes, such as arthritis in the spine. Insurers use these to argue your pain is age-related. A doctor can explain whether the accident made a quiet condition painful, which is usually still compensable.
  4. Future treatment. Findings can support the need for surgery or follow-up imaging.

Getting your scans

Ask for both the radiologist's written report and the images themselves, often on a disc or through a patient portal. Your lawyer or medical expert may need the images, not just the summary. In the US, HIPAA gives you the right to access your records. In the UK, you can make a subject access request. In Canada, provincial privacy laws give similar rights.

Radiation and repeat scans

CT uses more radiation than a standard X-ray. Don't ask for extra scans just to help a claim. Follow your doctor's advice about what's medically needed.
