下肢动脉阻塞疾病的诊断方法很多,彩超、磁共振血管成像(MR angiography,MRA)、CT增强、数字减影血管造影(d igitalsubtraction angiography,DSA)、选择性血管造影术等。每种方法各有优缺点。16层螺旋CT下肢动脉血管成像弥补了上述方法的一些不足,是一项高度准确的成像技术和非
There are many diagnostic methods for arterial occlusive disease of the lower extremity. Color Doppler ultrasound, MR angiography (MRA), CT enhancement, digital subtraction angiography (DSA), selective angiography and so on. Each method has its advantages and disadvantages. 16-slice spiral CT lower extremity arterial vascular imaging to make up for some of the deficiencies of the above method is a highly accurate imaging technology and non
