This paper has reported the accuracy of the duplex scanner in diagnosing occlusive disease of the carotid artery. Patients who present with vague neurologic symptoms, syncopal episodes, or asymptomatic carotid bruits are candidates for this type of study to determine the presence of significant stenosis. Other indications include the continuing assessment of known lesions and postoperative results in patients who have had endarterectomies.
本文报道了双功扫描仪在诊断颈动脉闭塞性疾病方面的准确性。出现模糊神经症状、晕厥发作或无症状颈动脉杂音的患者是这类检查的对象，以确定是否存在明显狭窄。其他适应症包括对已知病变的持续评估以及对接受了动脉内膜切除术患者的术后结果评估。
