Initial CT scan results are prognostic indicators for TBI outcomes.

Initial CT scan results are prognostic indicators for TBI outcomes.

• A. False.
• B. Not used.
• C. True.
• D. Only for pediatric cases.

Answer: (C)

Initial CT findings reflect the amount and pattern of brain injury that drive prognosis and guide urgent management in moderate to severe TBI. The CT scan on presentation can reveal mass effect from hematomas, midline shift, compressed or herniation, diffuse or focal contusions, subarachnoid or intraventricular blood, and cerebral edema. Each of these features is associated with higher risk of deterioration, the need for surgical intervention or ICP monitoring, and worse functional outcomes or mortality. Clinically useful CT-based frameworks, such as the Marshall classification, quantify the injury burden (swelling, basal cistern status, presence of mass lesions, and diffuse injury grade), helping to stratify prognosis early. Additional scoring systems refine this by incorporating subarachnoid blood and other CT details that correlate with outcomes. Of course, CT is one piece of the prognostic puzzle. A patient’s age, initial level of consciousness, pupil reactivity, physiologic status, and evolving clinical course also shape prognosis. But because it rapidly reveals the structural injury that largely determines early risk and potential for recovery, the initial CT is a strong prognostic indicator in TBI.
