计算机断层扫描血管造影在中枢神经系统疾病中应用的研究进展

Research Advance on Computed Tomography Angiography in Central Nervous System Diseases

随着多层螺旋计算机断层扫描及重组技术的发展,由于计算机断层扫描血管造影(computed tomography angiography,CTA)具有操作简便、微创的特点,其在中枢神经系统的应用越来越广泛,它不仅可为急性脑血管病、动脉瘤、脑动静脉畸形、烟雾病、脑静脉血栓形成及脊髓血管病变的诊断提供依据,对预测脑出血后血肿的再扩大也有重要意义。本文将就CTA在这些疾病中的技术优势、技术特点以及临床研究热点做一综述。

With the development of multi-slice computer tomography scan and recombinant techniques, computed tomography angiography（CTA） is widely used in central nervous system due to its convenient operation and minimal invasion. It contributes to the diagnosis of acute cerebral vascular diseases, aneurysm, arteriovenous malformations, moyamoya disease, tumors and spinal vascular disease, and provides evidence to the growth of massive hematoma. This paper reviews the imaging advantage, imaging technology and clinical research focus of CTA in the diseases.
