Noninvasive techniques have assumed an increasingly important role in the management of patients with vascular disease. Both ultrasonic and plethysmographic instruments allow objective evaluation of vascular disorders by the measurement of segmental limb blood pressures, analysis of blood velocity disturbances, recording of digit or limb pulse waveforms, or imaging of vascular disease, with or without Doppler flow analysis or color-flow mapping. These techniques have been applied for screening asymptomatic individuals, diagnosis of symptomatic patients, monitoring of interventional or surgical procedures, and follow-up of the natural history or the efficacy of medical, interventional, or surgical therapy of vascular disease. This article reviews the clinical application of these modalities to patients with peripheral arterial disease and briefly discusses cost-effectiveness and potential abuses of noninvasive technology.
非侵入性技术在血管疾病患者的管理中发挥着越来越重要的作用。超声和体积描记仪器都可以通过测量肢体节段血压、分析血流速度紊乱、记录手指或肢体脉搏波形，或对血管疾病进行成像（无论有无多普勒血流分析或彩色血流图）来客观评估血管疾病。这些技术已被应用于筛查无症状个体、诊断有症状的患者、监测介入或外科手术，以及跟踪血管疾病的自然病程或药物、介入或手术治疗的疗效。本文回顾了这些方法在周围动脉疾病患者中的临床应用，并简要讨论了非侵入性技术的成本效益和潜在滥用情况。
