摘要 目的探讨256层CT全脑灌注联合CT血管造影(CTP-CTA)在急性脑梗死中的临床应用价值。方法对20例急性脑梗死患者行全脑灌注成像,一次对比剂注射,一站式检查完成CT平扫、脑灌注成像以及CT血管成像,全面评估脑梗死。结果 20例患者梗死区供血血管狭窄19例,闭塞1例。梗死中心平均通过时间(MTT)和达峰时间(TTP)明显延长,脑血容量(CBV)和脑血流量(CBF)明显下降,与健侧区差异均有统计学意义(均<0.05)。周边区TTP和MTT延长,CBV增高,CBF下降,与健侧区差异均有统计学意义(均<0.05)。结论 CTP-CTA方法简便,能准确判断缺血后脑组织的血液动力学改变,明确血管狭窄部位及程度,实现对急性脑梗死的全面评价。
