目的评价CT平扫、CT灌注成像(CTPI)与CT血管成像(CTA)相结合的技术在超急性期脑梗死(HCI)中的应用。方法对21例HCI患者行CT、CTPI和CTA检查,对比观察CT、CTPI和CTA图像,分析最终病灶大小与CTPI和CTA的关系。结果 21例脑梗死患者均于发病6 h内就诊。CT平扫仅于4例中见早期表现;CTPI在20例中发现灌注异常;CTA在16例中显示异常。结论 CTPI联合CTA能够在超早期有效地诊断脑梗死。
Objective To evaluate the application of CT combined with CT perfusion imaging (CTPI) and CT angiography (CTA) in hyperacute cerebral infarction (HCI). Methods Twenty-one patients with HCI underwent CT, CTPI and CTA examinations. The CT, CTPI and CTA images were compared and the relationship between the final lesion size and CTPI and CTA was analyzed. Results 21 cases of cerebral infarction patients were treated within 6 hours of onset. CT scan showed early appearance in only 4 cases; CTPI showed abnormal perfusion in 20 cases; CTA showed abnormality in 16 cases. Conclusion CTPI combined with CTA can effectively diagnose cerebral infarction in the early stage.
