Abstract：Objective: To explore the distinguishing meaning of CT perfusion (CTP) on the blood perfusion condition of the area of cranio-cerebral trauma focus. Methods: CT scanning was used in the patients with different cranio-cerebral trauma. Furthermore, CTP was used to examine those lesions with low-density shadow surrounding, while an analysis of the parameters of mean transit time (MTT), regional cerebral blood flow (rCBF) and regional cerebral blood volume (rCBV), and a comparison of patient prognoses were also conducted. Results: CT scan showed low-density focus of the brain parenchyma around the site of the trauma in 79 cases; CT perfusion parameters showed hypo-perfusion of the brain tissue around the trauma in 42 cases (54.4%), high perfusion in 35 cases (44.3%), while there were no obvious brain tissue perfusion abnormalities in 2 cases. Prognosis of low perfusion was poorer. Conclusion: CT examination should apply further CTP in the case of those patients who have been found to display low-density shadow around their cranio-cerebral trauma, in order to help clinicians to better understand the local haemodynamic state of the brain tissue. This has great significance on the diagnosis of focus microcirculation disturbance of cranio-cerebral trauma.
