To evaluate and compare the characteristics of the regional cerebral blood flow in patients with mild cerebral concussion or injury using the results of perfusion computed tomography (CT).
Thirty-eight men, aged 18-35 years, including 21 with concussion and 17 with mild cranial/brain injury (CBI), were examined at the early stage of disease. The control group consisted of 7 age-matched men with non-confirmed CBI.
The results of CT-perfusion revealed generalized changes in the hemodynamics. There was a significant increase in the mean time and decrease in the total volume of blood flow through selected regions. Hypoperfusion caused by generalized vasospasm was found in all patients at the early stage of mild CBI. Focal disturbances of cerebral blood flow localized in the poles of the frontal and temporal lobes were determined in patients with mild brain injury compared to the patients with concussion. The use of CT-perfusion can improve the diagnosis of mild CBI.
利用灌注计算机断层扫描（CT）结果评估并比较轻度脑震荡或脑损伤患者的局部脑血流特征。
对38名年龄在18 - 35岁的男性进行了检查，其中包括21名脑震荡患者和17名轻度颅脑损伤（CBI）患者，均在疾病早期进行检查。对照组由7名年龄匹配、未确诊CBI的男性组成。
CT灌注结果显示血流动力学存在全身性变化。所选区域的平均时间显著增加，血流总量减少。在轻度CBI早期，所有患者均发现因全身性血管痉挛导致的灌注不足。与脑震荡患者相比，轻度脑损伤患者的脑血流局部紊乱定位于额叶和颞叶的极部。CT灌注的应用可改善轻度CBI的诊断。
