Intravascular sonography is a valuable tool for the morphologic assessment of coronary atherosclerosis and the effect of pharmacologic and nonpharmacologic interventions on the progression or stabilization of atherosclerosis. An analysis of the different modes, applications, and limitations is provided on the basis of review of existing data from multiple clinical case studies, trials, and mechanistic studies. Intravascular sonography has been used to assess the outcomes of different percutaneous interventions, including angioplasty and stent implantation, and to provide detailed characterization of atherosclerotic lesions, aneurysms, and dissections within the cerebrovascular circulation. Evolution of intravascular sonographic technology has led to the development of more sophisticated diagnostic tools such as color-flow, virtual histology, and integrated backscatter intravascular sonography. The technologic advancement in intravascular sonography has the potential of providing more accurate information prior, during, and after a medical or endovascular intervention. Continued assessment of this diagnostic technique in both the intracranial and extracranial circulation will lead to increased use in clinical practice with the intent to improve outcomes.
血管内超声是评估冠状动脉粥样硬化形态学的一种有价值的工具，也是评估药物和非药物干预对动脉粥样硬化进展或稳定的影响的一种有价值的工具。本文基于对多项临床病例研究、试验和机制研究的现有数据的回顾，对不同模式、应用和局限性进行了分析。血管内超声已用于评估不同经皮介入治疗（包括血管成形术和支架植入术）的结果，并对脑血管循环中的粥样硬化病变、动脉瘤和夹层进行详细的特征描述。血管内超声技术的发展带来了更复杂的诊断工具，如彩色血流、虚拟组织学和背向散射积分血管内超声。血管内超声技术的技术进步有可能在医疗或血管内干预之前、期间和之后提供更准确的信息。持续评估这种诊断技术在颅内和颅外循环中的应用，将导致其在临床实践中的应用增加，目的是改善治疗效果。
