amp;nbsp;CT angiography (CTA) has revolutionized vascular imaging. Vessels smaller than 1mm in diameter can be visualized with single slice CTA and vessels 2 mm or more in diameter can be diagnostically evaluated. The acquisition of 3D data volumes makes it possible to generate angiographic views...

前循环缺血性卒中在发病6小时内进行血管内治疗已被证实是有效和安全的。本研究(MR CLEAN-LATE)旨在评估血管内治疗在晚时间窗(症状发作后或在患者最后一次已知健康状况良好后6-24h内)且CT血管造影(CTA)显示存在侧支血流的患者中的疗效...
传统的动脉成像技术包括CT血管成像(CT angiography,CTA)、磁共振血管成像(magnetic resonance angiography,MRA)、数字减影血管造影(digital subtraction angiography,DSA)等均无法评估ICAS易损斑块的部位、大小、形态、信号及强化特征等信息。 高...

The most common reason of damage of extracranial carotid arteries is atherosclerosis. Atherosclerosis is a chronic disease, which develops in the result of disorder of lipid and protein metabolism. Elastic and muscular-elastic arteries get damaged following focal accretions of lipids and proteins in ...
与普通 X线计算机体层成像( computed tomography,CT)相比,磁共振成像的昀大优势在于,它是对人体没有任何伤害且安全、快速、准确的临床诊断方法。 1.极高的图像分辨率在所有医学影像学手段中, MRI的软组织分辨率昀高。不同于依靠 X线吸收率的不同来区分组织之间差异的 X线、CT,MRI的...
