摘要
对29例原发性高血压患者用^(99m)Tc-ECD SPECT进行脑血流灌注显像。结果:93％的Ⅱ到Ⅲ期病例有局限性脑血流灌注异常。83％的病例白质区有低灌注或缺血灶,45％的病例基底节区和45％的病倒皮质区有低灌泣或缺血灶。有两处或以上血流灌注异常灶者占73％。结果表明:脑血流灌注显像探查脑小血管病变所致局限性血流灌注异常较灵敏。
29 patients with hypertension were examined using～(99m)Tc-ECD SPECT to study theregional cerebral blood flow. The result showed that 93% cases of stage Ⅱ and Ⅲ had abnormal rCBFfoci. 83% cases showed regional hypoperfusion or ischemia foci in white substance, 45% in basalganglion and 45% in cortical area. 73% cases had 2 or more foci with abnormal perfusion. The resultsuggests that the SPECT cerebral blood flow imaging is useful to early detect abnormality of rCBF of thepatient with hypertension.
