Computed tomography scan, also known as CT scan or CAT scan, is an important tool for the assessment of patients with traumatic brain injury. The CT scan is a type of x-ray image procedure where a continuous tube with a beam of x-rays rotates while the patient moves through the scanner. During this process a series of pictures are taken that provide a comprehensive view of the brain from different views. The CT scan is the most commonly used imaging technique for diagnosis and to guide treatment decisions.
