He specifies above a dozen characters which may be found varying even on the same branch . 他指出在同一枝條上進行變異的12種以上的特征。
Conclusion : color doppler flow imaging is a useful noninvasive method for the diagnosis of vertebral artery course variation 結論:彩色多普勒超聲對椎動脈走行變異是一種理想的無創(chuàng)性診斷方法。
Objective to evaluate the diagnostic value of color doppler flow dynamic changes in patients with vertebral artery course variation 摘要目的:研究椎動脈走行變異患者推動脈血流動力學的超聲診斷價會值。
Results : the sonographic manifestations in the ipsilateral course variation vertebral artery revealed that the diameter and flow velocity were decreased , pi and ri were increased 結果:椎動脈走行變異其變異側椎動脈超聲表現(xiàn)為:管徑較窄, pi和ri較高,流速較低。
Methods : the blood flow parameters of 113 patients with vertebral artery course variation among 1161 patients with cervical spondylopathy were statistically analyzed and compared to the control group 方法:用彩色多普勒對頸椎病患者進行檢測,從1161例頸椎病中篩選出113例椎動脈走行變異患者,對變異側內(nèi)徑和血流參數(shù)與對照組進行統(tǒng)計學比較。
