Determining the presence and characteristics of vascular flow is an essential part of sonography interrogation. However, small vessels and low velocities are not always possible to depict with conventional color and power Doppler ultrasound. This can be frustrating, especially when the diagnosis depends mainly on the existence of vascular flow, the sonographic examination will be inconclusive, further imaging examinations will be required and diagnosis delayed. Superb microvascular imaging (SMI) is a novel vascular imaging mode, which provides visualization of low velocity and microvascular flow. SMI uses a clutter suppression algorithm to extract flow signals and depicts this information as a color overlay image or as a monochrome or color map of flow. By using SMI, high frame rates and high-resolution images remain maintained. With SMI, it is possible to visualize small vessels including their branches that, until now, it is possible to demonstrate only using contrast-enhanced ultrasound. Availability of this additional technology on all ultrasound machines may make some of the computed tomography scans unnecessary. In our paper, we describe six patients, aged 16-73 years, in which final diagnosis was achieved only with SMI and where conventional color and power Doppler failed. All these examinations were performed using Aplio 500 Platinum ultrasound unit (Toshiba Medical Systems, Tokyo, Japan).
确定血管血流的存在及其特征是超声检查的重要组成部分。然而，小血管和低速血流并不总是能用传统的彩色和能量多普勒超声显示出来。这可能会令人沮丧，尤其是当诊断主要取决于血管血流的存在时，超声检查可能无法得出结论，就需要进一步的影像学检查，从而导致诊断延迟。超微血管成像（SMI）是一种新型的血管成像模式，它能显示低速血流和微血管血流。SMI使用一种杂波抑制算法来提取血流信号，并将这些信息描绘为彩色叠加图像或血流的单色或彩色图。通过使用SMI，可以保持高帧率和高分辨率图像。使用SMI，可以显示包括其分支在内的小血管，而到目前为止，这些小血管只有使用超声造影才能显示。所有超声设备都具备这项附加技术，可能会使一些计算机断层扫描变得不必要。在我们的论文中，我们描述了6例年龄在16至73岁之间的患者，这些患者仅通过SMI获得了最终诊断，而传统的彩色和能量多普勒检查均失败。所有这些检查均使用Aplio 500 Platinum超声设备（日本东京东芝医疗系统公司）进行。
