周围血管病变包括肢体动脉血管和静脉血管的疾病。我国60岁以上的人群中,动脉硬化闭塞性疾病的发病率约为7.97%。下肢动脉血管疾病在周围血管疾病中所占比例逐渐上升,后果十分严重。传统血管造影(DSA)的金标准地位目前已受到无创性检查技术的极大挑战。而彩色多普勒超声的结果与操作者的技术水平有明显关系,也难以检出高度狭窄或闭塞远段的病变。MR血管造影(MRA)虽然愈来愈多地用于显示周围血管疾病,但MRA的空间分辨力低、耗时,有幽闭恐怖症以及携带维持生命的电子仪器者禁
Peripheral vascular lesions include diseases of the arterial and venous limbs. China’s population over the age of 60, the incidence of arteriosclerosis occlusive disease was about 7.97%. Lower extremity arterial disease in the proportion of peripheral vascular disease gradually increased, the consequences are very serious. The gold standard of traditional angiography (DSA) has now been challenged by noninvasive techniques. The color Doppler ultrasound results and the operator’s skill level has a clear relationship, it is also difficult to detect a high degree of stenosis or occlusion distal lesions. MR Angiography (MRA) Although more and more used to show peripheral vascular disease, MRA has low spatial resolution, time-consuming, with claustrophobia and life-sustaining electronic devices banned
