The enormous success of Ultrasound is derived from its good spatial resolution and diagnostic accuracy. The most recent and most important application of Ultrasound is Color Doppler. Color Doppler has introduced the dynamic factor, allowing the superimposition, on the high-resolution image, of flow information. For the first time, detailed and non-invasive information is obtained that is not only morphological, but also functional, through the visualisation of organ flow and perfusion. The clinical applications of Color Doppler are briefly discussed, encompassing areas that have long been studied by Duplex Doppler, such as the carotid-vertebral and the peripheral vessels. The most recent applications are also reviewed, namely: Tissue characterisation; Hemodynamics of portal hypertension and arterial hypertension; The evaluation of renal and hepatic transplants; and erectile dysfunction studies.
超声的巨大成功源于其良好的空间分辨率和诊断准确性。超声最新且最重要的应用是彩色多普勒。彩色多普勒引入了动态因素，使得血流信息能够叠加在高分辨率图像上。通过可视化器官的血流和灌注情况，首次获得了不仅是形态学的，而且是功能性的详细且非侵入性信息。本文简要讨论了彩色多普勒的临床应用，涵盖了长期以来由双功多普勒研究的领域，如颈动脉 - 椎动脉和外周血管。还回顾了其最新应用，即：组织特征分析；门静脉高压和动脉高血压的血流动力学；肾和肝移植的评估；以及勃起功能障碍研究。
