多层CT血管造影对超早期大面积脑梗塞的诊断作用

目的 评价多层CT血管造影（MS—CTA）对超早期大面积脑梗塞的诊断作用。方法 临床怀疑超早期（出现症状6小时内）大面积脑梗塞的病人20例，均在CT平扫后进行CTA检查。结果 20例病人MS—CTA都得到了可以达到诊断目的的高质量动脉图像。在所有影像和临床随访证实为非腔隙性脑梗塞的13例中．MS—CTA均看到了潜在的血管病变。结论 对于急性早期大面积脑梗塞的病例，MS—CTA是迅速和综合评价脑血管的有力手段。

Multi-slice CT angiography in the evaluation of patients with hyperacute cerebral infarction

Objective To evaluate the suitability of multi-slice CTA (MS-CTA) for patients with hyperacute cerebral infarction. Material and Methods 20 patients with clinically suspected hyperacute cerebral infarction. underwent CTA in a MS-CT scanner after no contrast scan. All findings were reviewed for stenoses or occlusion of the intracranial artery. Results In all patients, MS-CTA intracranial CVS yielded images of diagnostic quality with comprehensive visualization of the arterial CVS including the third segment of the major cerebral arteries. In all patients, in whom imaging and clinical follow-up proved a non-lacunar infarction (n=13), MS-CTA detected the underlying vascular pathology. Conclusions Multi-slice CT angiography may be a new diagnostic tool for the rapid and comprehensive assessment of the intracranial CVS in patients with clinical signs of hyperacute cerebral infarction.
