16层螺旋CT颈内动脉血管造影的临床应用

目的探讨多层螺旋CT血管成像(MSCTA)技术在颈内动脉中的临床应用价值。方法回顾性分析58例疑为颈内动脉病变患者所做的16层螺旋CT颈内动脉造影图像。对扫描数据进行容积再现技术(VRT)、最大密度投影(MIP)、多平面重建(MPR)、曲面重建(CPR)、仿真内镜(CTVE)等图像后处理。结果58例中17例无明确异常;41例有不同程度的颈内动脉病变,其中颈内动脉瘤9例,动脉狭窄23例,动脉阻塞4例,5例5枚支架有2枚显示通畅,2枚有软斑块形成,1枚支架阻塞。结论16层螺旋CT颈内动脉血管造影成像能很好地显示颈内动脉管腔狭窄及斑块形成情况,很好的评估颈内动脉支架植入情况,是一种有效的无创性颈内动脉疾病检查方法。

Clinical Application of 16-slice Spiral CT Angiography in Internal Carotid Artery

Objective To study the clinical application of multi-slice spiral CT angiography(MSCTA)in internal carotid artery.Methods A total of 58 patients suspected internal carotid diseases underwent MSCTA of internal carotid artery were reviewed.The scanning data was used to perform 3D reconstruction with volume rendering technique(VRT),maximum intensity projection(MIP),multiplanar reconstruction(MPR),curved planar reconstruction(CPR) and CT virtual endoscopy(CTVE).Results Of 58 cases,17 cases were normal,different stages of internal carotid artery diseases were revealed in 41 cases including 9 cases of aneurysm,23 cases of artery stenosis,4 cases of occlusion,of 5 stents planted in 5 cases,soft plaque suspected in 2 case and occlude in 1.Conclusion The 16-slice spiral CT angiography is superior modality in evaluation of internal carotid stenosis,plaques,and stents.As a minimally invasive examination,MSCTA is a valuable method to detect the diseases of internal carotid artery.
