摘要
目的探讨多层螺旋CT血管造影(MSCTA)对烟雾病的诊断的检查技术要点、影像表现和临床应用前景。方法采用16层螺旋CT行脑CTA检查,后处理技术为容积再现(VR)、多平面重建(MPR)及最大密度投影(MIP)。结果CTA能清晰显示颈内动脉颅内段、脑基底动脉环等部位血管狭窄、闭塞的形态,管壁状况及狭窄程度,且能清晰显示增多迂曲的脑基底部的异常血管网。结论CTA检查可作为烟雾病首选的检查方法,对临床的治疗有指导作用。
Objective To investigate the multi-slice spiral CT angiography （MSCTA） for the diagnosis of moyaraoya disease inspection techniques, imaging findings and clinical applications. Methods 16-slice CT cerebral CTA examination, post-processing techniques for volume rendering （VR）, multiplanar reconstruction （MPR） and maximum intensity projection （MIP）. Results CTA can clearly show that intracraulal segment of internal carotid artery, cerebral arterial rings and other parts of the base of vascular stenosis, occlusion of the morphology, wall conditions and degree of stenosis, but also to clearly indicate that an increase in brain-based tortuous abnormal vascular network at the bottom. Conclusion CTA can be used as moyamoya disease check preferred method of examination and clinical treatment has the guiding role.
