[摘要] 目的探讨螺旋 CT 脑灌注成像技术在超早期脑梗死诊断中的价值。方法分析总结 12 例发病在 6h 内临床可疑脑梗
死,对其进行了 CT 平扫、CT 脑灌注检查和 CT 复查住院患者资料,并对灌注资料做统计学分析。结果 CT 平扫 2 例脑实质
密度轻微减低、脑沟变浅(17%),CT 脑灌注 10 例显示与临床症状对应区域血流灌注异常(83%),与对侧比较 CBF、CBV 下
降,MTT 延长。24~72h CT 复查血流灌注异常区域全部出现大小不等低密度脑梗塞灶。2 例对于 CT 平扫、CT 灌注及复查均
未见异常(17%)。结论常规 CT 平扫对超早期脑梗死诊断有限,不能满足临床的要求。CT 脑灌注成像技术对超早期脑梗
死诊断有重要的临床应用价值。

[Abst ract ] Object ive To investigate the application of spiral CT cerebral perfusion imaging in the diagnosis of acute infarction.
Met hods The data were analyzed of 12 patients,who fell ill in 6 hours,suspected of having acute ischemic infarction,were examined
by non- puted tomography(CT),CT perfusion and examination by non- enhanced CT. These data were analyzed statistically.
Result s Non- enhanced CT scanning showed a slight reduction in the density of brain parenchyma in two cases,with brain shallow
groove (17%)and CT perfusion showed perfusion abnormalities corresp
