16排螺旋CT血管造影在脑血管病变诊治中的临床应用

The Clinical Value of 16-slice Spiral CT Angiography for the Patients with Cerebral Vascular Disease

目的:探讨16螺旋CT脑血管造影在脑血管病变诊治中的临床应用价值。方法:对我院收治的52例脑血管病变患者的16排CTA检查资料进行回顾性分析,并以容积重建(VR)、最大密度投影(MIP)重建和多平面重建(MPR)技术对脑血管影像表现进行评价分析。结果:52例脑血管病变中诊断出颅内动脉瘤49例,脑内动静脉血管畸形(AVM)3例。52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,也清晰显示了AVM的畸形血管团、供血动脉和引流静脉。结论:16排螺旋CT脑血管造影成像技术是一种无创伤的颅内血管性病变检查方法。它具有无创、快捷、安全、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。

Objective： To explore the clinical value of 16-slice spiral CT angiography for cerebral vascular disease.Method： Retrospectively analyzed the clinical datas of 52 patients with cerebral vascular disease who were examined by 16-slice spiral CT in our hospital,and evaluated the image of cerebral vascular by volume rendering（VR）,maximum intensity projection（MIP） reconstruction and multi-planar reconstruction（MPR） technique.Result： 49 cases with intracranial aneurysms,3 cases with brain arteriovenous malformation（AVM） in 52 cases cerebral vascular disease.52 cases of 16-slice CTA of VR,MIP and MPR reconstruction imaged to the trunk and main branches of cerebral blood vessels show 100%,and clearly showed the aneurysm＇s location,shape,size,and with the surrounding blood vessels and the relationship between the skull,also clearly showed the AVM＇s abnormal vascular group,feeding arteries and draining veins.Conclusion： 16 slice spiral CT angiography is a non-invasive imaging technique of intracranial vascular disease screening method.It has non-invasive,fast,safe,high accuracy characteristics,and can be used as the preferred and effectived screening method for the diagnosis of cerebral vascular disease.
