摘要
目的 评价CT灌注成像在脑缺血性疾病中的作用。方法 对 11例缺血性疾病发作 3h至 2 3d的患者行常规CT和CT灌注成像 ,5例进行MRI检查 ,2例行DSA检查。结果 11例患者CT平扫共检 4例 ,CT灌注成像共检出 6例 ,均经随访CT、MRI及DSA证实。 7例表现为CBF下降 ;7例MTT延长 ;6例无TP出现 ;4例CBV下降。 1例起病后 10hCBF、CBV增加 ,MTT、TP无变化。 1例起病后 10d病灶表现为MTT、TP延长 ,CBV下降。结论 结合常规CT及MRI、DSA扫描 ,CT灌注成像不仅有利于显示超急性期脑缺血病灶 。
Purpose To evaluate the application of CT perfusion in intra-axial disease.Methods 11 patients with intra-axial ischemis disease were analyzed.7 were males,4 females.11cases with CT imaging and CT perfusion imaging,5 cases with MRI examination,2 cases with DSA examination.Results 6 cases were determined with CT perfusion imaging,confirmed by follow-up CT,MRI and DSA.4 cases were identified with regular CT images.Of the patients,7 cases were with low CBF and 4 cases with low CBV,7 cases with long MTT.One case was ill with long MTT and long TP and low CBV after coming down with the illness for 10 days.Conclusions Combined with regular CT?MRI and DSA images,CT perfusion imaging not only is useful in demonstrating the hypercute ischemic storke,but also can show the hemodynaqmic changes of intra-axial ischemic lesions caused by other reasons.
