编者按临床实践方式经历了过去基于症状的经验医学,到目前基于证据的循证医学。近年来精准医学的概念逐渐兴起,对于脑血管病来说,结合现代影像学技术对脑血管形态、血流动力学及血管功能进行精准化评估,可能距离脑血管病精准治疗目标越来越近。目前从形态学上可利用经颅多普勒超声、数字减影血管造影及高分辨率磁共振成像等明确血管的狭窄程度、斑块特征等;另外可应用计算机断层扫描、 The editors went through the history of symptom-based empirical medicine in clinical practice to evidence-based evidence-based medicine. In recent years, the concept of precision medicine is gradually emerging. For cerebrovascular disease, the accurate assessment of cerebrovascular morphology, hemodynamics and vascular function in combination with modern imaging techniques may be closer and closer to the goal of precise treatment of cerebrovascular disease . Currently morphologically available transcranial Doppler ultrasound, digital subtraction angiography and high-resolution magnetic resonance imaging and other clear vascular stenosis, plaque features; the other can be applied to the computer tomography,
