Paralleling recent developments in noninvasive vascular imaging of the carotid bifurcation, there have been several randomized therapeutic trials for carotid stenosis to identify which patients should receive treatment. Studies involved in neuroimaging have sought ways to evaluate carotid artery stenosis without standard angiography, whereas those involved in therapeutic decisions for patients with carotid stenosis have attempted to verify the use of carotid endartectomy and determine which patients benefit most from treatment. The methods of measurement for carotid stenosis, duplex ultrasound measurement comparisons, magnetic resonance angiography and computed tomographic angiography, and standard radiographic angiography are discussed.
与颈动脉分叉处无创血管成像的最新进展相平行，已经有几项针对颈动脉狭窄的随机治疗试验，以确定哪些患者应该接受治疗。涉及神经成像的研究一直在寻找无需标准血管造影就能评估颈动脉狭窄的方法，而涉及颈动脉狭窄患者治疗决策的研究则试图验证颈动脉内膜切除术的应用，并确定哪些患者从治疗中获益最大。本文讨论了颈动脉狭窄的测量方法、双功超声测量比较、磁共振血管造影和计算机断层血管造影以及标准放射学血管造影。
