Helical CT angiography provides a means to rapidly and noninvasively evaluate the vasculature, both intracranially and extracranially, in acute, subacute, and chronic stroke settings and thus to provide potentially important information about the presence of vessel occlusions or stenoses.

螺旋CT血管成像（helical CT angiography， helical CTA）可以快速、无创地评价急性、亚急性、慢性卒中时颅内及颅外血管状况；因此，可以提供血管闭塞或狭窄的信息。该技术用于急性卒中患者的可行性已被证实。
