Abstract

Aim To assess the usefulness of CT perfusion scans of the brain in patients with traumatic brain injury having cerebral contusion on CT scan.

Material and Methods This prospective study included 76 patients with cerebral contusion on plain CT of the brain, aged 5 to 86 years, admitted in our institution. They underwent perfusion CT as part of their admission CT survey and follow-up scan 48 hours later. Clinical data, unenhanced CT brain findings, and perfusion CT scans were evaluated with respect to the postoperative GCS (Glasgow Coma Score) and neurologic deficit.

Results Perfusion CT gave additional information when done with conventional unenhanced CT in the detection of cerebral contusions. Perfusion CT featured specific patterns with respect to patient outcome, patients with unfavorable outcome having significant decrease in cerebral perfusion. In patients having less GCS score, a significant decrease in cerebral blood flow and cerebral blood volume was detected.

Conclusion Perfusion CT provides independent useful information regarding functional outcome. In the acute phase of mild head injury, disturbed cerebral perfusion is seen in patients with normal noncontrast CT correlating with evolution, severity of injury, and outcome.
