In February 2018, a blood test to evaluate mild traumatic brain injury in adults was approved by the FDA. Those with mild to moderate head injuries could receive skull and neck x-rays to check for bone fractures or spinal instability. Moderate to severe cases of TBI might receive a CT scan. This technology uses a series of x-rays to create a detailed view of the brain and can uncover evidence of bleeding in the brain, blood clots, bruised brain, and brain tissue swelling. Magnetic resonance imaging (MRI) uses powerful radio waves and magnets to create a detailed view of the brain and is generally used after the individual’s condition stabilizes.
