Abstract

Microvascular flow imaging (MVFI) is an advanced Doppler ultrasound technique designed to detect slow-velocity blood flow in small-caliber microvessels. This technique is capable of realtime, highly detailed visualization of tumor vessels without using a contrast agent. MVFI has been recently applied for the characterization of focal liver lesions and has revealed typical vascularity distributions in multiple types thereof. Focal nodular hyperplasia (FNH) constitutes an important differential diagnosis of malignant liver tumors. In this essay, we provide iconographic documentation of the MVFI appearance of FNH and other common solid liver lesions. Identifying the typical patterns of vascularity, including the spoke-wheel pattern with MVFI, can expedite the diagnosis, spare patients from unnecessary procedures, and save costs.

微血管血流显像鉴别局灶性肝脏病变:轮辐型是局灶性结节增生的特殊征象。

微血管血流成像(MVFI)是一种先进的多普勒超声技术，用于检测小口径微血管中的慢速血流。该技术无需使用造影剂即可实时、详细地显示肿瘤血管。MVFI最近被应用于局灶性肝脏病变的表征，并显示了多种类型的典型血管分布。局灶性结节性增生(FNH)是恶性肝肿瘤的重要鉴别诊断。在这篇文章中，我们提供了FNH和其他常见实性肝脏病变的MVFI图像记录。识别典型的血管分布模式，包括MVFI的辐轮模式，可以加快诊断，使患者免于不必要的手术，并节省成本。

期刊介绍： Ultrasonography, the official English-language journal of the Korean Society of Ultrasound in Medicine (KSUM), is an international peer-reviewed academic journal dedicated to practice, research, technology, and education dealing with medical ultrasound. It is renamed from the Journal of Korean Society of Ultrasound in Medicine in January 2014, and published four times per year: January 1, April 1, July 1, and October 1. Original articles, technical notes, topical reviews, perspectives, pictorial essays, and timely editorial materials are published in Ultrasonography covering state-of-the-art content. Ultrasonography aims to provide updated information on new diagnostic concepts and technical developments, including experimental animal studies using new equipment in addition to well-designed reviews of contemporary issues in patient care. Along with running KSUM Open, the annual international congress of KSUM, Ultrasonography also serves as a medium for cooperation among physicians and specialists from around the world who are focusing on various ultrasound technology and disease problems and relevant basic science.
