摘要
目的:探讨16排螺旋CT减影后血管成像在颈动脉闭塞性疾病的应用价值。方法:36例患者先后进行平扫及增强扫描,原始数据传入工作站,以平扫图像为蒙片进行减影,最后进行三维血管成像处理,评价图像质量及病变的影像表现,其中8例进行了DSA检查。结果:血管重建后总体可评价率为91·5%,共发现病变血管28支,其中轻度狭窄10支,中度狭窄6支,重度狭窄8支,闭塞4支。8例DSA检查结果与DS-CTA一致。结论:16排螺旋CT减影后血管成像可以提供高质量的重建图像,在诊断颈动脉闭塞性疾病方面有很高的应用价值,可以为临床治疗提供指导。
Objective：To explore the value of subtraction 16-slice CT in occlusive disease of carotid artery. Methods：Thirty four patients underwent precontrast and postcontrast, the data were transfered to workstation for subtracting, at last for 3D reconstruction, two radiologists assessed the image quality and analyzed the disease, 8 patients also accepted DSA exam.Results：91.5% arteries of all could be assessed, 28 diseased arteries were diagnosed,includlng mild stenosis 10, moderate stenosis 6, severe stenosis 8, occlusion 4. The results of DSA were concordant with DS-CTA. Conclusion： Subtraction 16-slice spiral CT angiography can acquire good imaging quality,it has high value in diagnosing occlusive disease of carotid artery and can provide advice for treatment.
