Objective, accurate and noninvasive assessment of the condition and prognosis of traumatic brain injury (TBI) patients in the early stage is the basis of TBI treatment. Glasgow coma scale (GCS) is the most common clinical method for assessing trauma condition. However, when patients are sedated, intubated or have language or movement disorders, it is often impossible to make an accurate assessment by GCS. In addition, GCS cannot provide direct evidences of pathological damage in brain tissues. The CT scoring system has emerged in recent years and is a non-invasive evaluation system based on CT images. The evaluation process can objectively reflect the severity of brain tissue damage without being interfered by sedation or intubation. The authors review the progress of researches on CT scoring systems to assess the prognosis of patients with craniocerebral injury, so as to provide a reference for clinicians to choose appropriate injury assessment methods and make clinical decisions.
