摘要
应用高场强磁共振设备及多种线圈、多序列扫描技术探测颈动脉粥样斑块,不仅能观察到斑块内脂核含量和纤维帽的厚度,斑块内出血、坏死等变化,还可以得到血管管壁形态学的改变、血管管腔及斑块自身的应力改变等多方面的信息;通过钆螯合对比剂及超顺磁性三氧化二铁制剂增强成像,可以了解斑块内炎性改变,这与斑块的发展和预后密切相关。因此,通过磁共振成像技术判定颈动脉粥样斑块的稳定性具有重要的临床意义。
With a high-power field magnetic resonance（MR）equipments,a variety of coils,and multi-sequential scanning for the detection of carotid atherosclerotic plaques,MR imaging can visualize the content of lipid core in plaques,the thickness of fibrous cap,and intraplaque hemorrhage,in addition to the histological changes in vascular walls,vascular lumens,and the stress alteration in plaques.Gadolinium-chelated contrast media and supramagnetic ferric oxide will help characterize the inflammatory presentations of plaque that is associated with the development and prognosis of plaque.Therefore,MR imaging plays a clinically significant role in the evaluation of the stability of atherosclerotic plaque.
