Computed tomography perfusion imaging on traumatic cerebral contusion: a preliminary report

Area of Science:

• Neuroimaging
• Traumatology
• Radiology

Background:

• Traumatic brain injury (TBI) frequently causes brain ischemia and infarction, leading to significant morbidity and mortality.
• Pericontusional hypodense areas are common findings in TBI, but their perfusion status requires detailed evaluation.

Purpose of the Study:

• To determine the perfusion status of pericontusional hypodense areas in traumatic cerebral contusions using computed tomography perfusion (CTP).

Main Methods:

• Ten patients with traumatic cerebral contusions from motor vehicle accidents were studied.
• Computed tomography (CT) scans diagnosed contusions, followed by computed tomography perfusion (CTP) to analyze hypodense areas divided into 4 regions of interest (ROIs).

Main Results:

• Ischemic perfusion was most prevalent in ROI 6 (60% of patients), though mean perfusion parameters were normal.
• A significant positive correlation was observed between perfusion in ROI 3 (near skull vault) and its distance to the skull vault (r = 0.698, P = 0.025).
• Adjacent ROIs 4 and 5 showed a significant positive correlation in perfusion status (r = 0.667, P = 0.035), suggesting edema and perfusion disturbances.

Conclusions:

• CTP is a valuable, rapid, and appropriate tool for evaluating perfusion in pericontusional hypodense areas.
• CTP findings can assist physicians in making informed treatment decisions for TBI patients.
