【摘要】 目的:探讨16层螺旋CT血管造影(CTA)对脑血管病变的临床应用价值。方法:对40例脑血管病变患者行16层螺旋CT血管造影(CTA)检查的影像资料进行回顾性分析,采用最大密度投影(MIP)、容积重建(VR)和多平面重建(MPR)技术进行三维重建后处理。结果:动脉瘤16例,动静脉畸形9例,动脉狭窄4例(右大脑前动脉狭窄3例,双侧大脑后动脉1例),先天发育异常(胎胚性大脑后动脉)11例,40例16排CTA的VR、MIP和MPR重建图像对脑血管主干及其主要分支显示100%,并且清晰显示动脉瘤的位置、形态、大小、以及与周围血管和颅骨的关系,同时清晰显示了AVM的畸形血管团、供血动脉和引流静脉。结论:16层螺旋CT血管造影成像技术(CTA)具有安全、快速、无创、准确性高的特点,可作为脑血管病变首选而有效的检查方法。更多还原

【Abstract】 Objective:To investigate the 16 slice spiral CT angiography (CTA) on cerebral vascular lesions clinical application value.Methods:40 cases of cerebral vascular lesions underwent 16 slice spiral CT angiography (CTA) examination of the imaging data were retrospectively analyzed,using a maximum intensity projection (MIP),volume rendering (VR) and multiplanar reconstruction (MPR) techniques for 3D reconstruction after treatment.Results:Among 40 cases,16 cases with aneurysm,arteriovenous malformation in 9 cases,4 cases of arterial stenosis (right anterior cerebral artery stenosis in 3 cases,bilateral posterior cerebral artery :report of 1 cases),congenital dysplasia ( embryo of posterior cerebral artery) in 11 cases,40 cases 16 CTA VR,MIP and MPR image reconstruction on the cerebral vascular trunk and its main branches show 100%,and clearly show the location of the aneurysm,shape,size,and peripheral vascular and skull of the relationship,and clearly shows the AVM malformations,feeding arteries and draining veins.Conclusion:16 slice spiral CT angiography imaging technology (CTA) is a safe,rapid,noninvasive,high accuracy,can be used as cerebrovascular lesions preferred and effective examination method.更多还原
