Interventional radiology applications of intravascular US (IVUS) continue to expand, complementing intraprocedural angiography and providing a unique vantage from which to guide endovascular interventions. Vascular pathologic conditions become sonographically visualized rather than inferred from the planar appearance of the opacified vascular lumen. Perivascular targets become sonographically visualized rather than approximated on the basis of fluoroscopic landmarks. The authors introduce broad categories of IVUS catheters, namely radial and side-firing varieties, as well as prevailing options for each and their technical specifications. Common applications within interventional radiology are covered in a systems approach, including deep venous thrombosis, May-Thurner syndrome, nutcracker syndrome, transjugular intrahepatic portosystemic shunts, aortic interventions, peripheral arterial disease, and endovascular or perivascular biopsy. Discussions are accompanied by technical pearls from the authors, and summarized evidence where IVUS has been shown to reduce procedural time, intravascular contrast agent dose, radiation exposure, and morbidity in each space is presented. Finally, emerging applications and future directions are discussed. RSNA, 2022.
血管内超声（IVUS）的介入放射学应用不断扩大，与术中血管造影相辅相成，为血管内介入提供了独特的视角。血管病变可以通过超声可视化，而不是从血管腔的显影平面推断出来。血管周围的靶标可以通过超声可视化，而不是根据透视标志进行近似估计。作者介绍了 IVUS 导管的广泛类别，即径向和侧射型，以及每种导管的流行选择及其技术规格。采用系统方法介绍了介入放射学中的常见应用，包括深静脉血栓形成、May-Thurner 综合征、胡桃夹综合征、经颈静脉肝内门体分流术、主动脉介入、外周动脉疾病以及血管内或血管周围活检。讨论中附有作者的技术要点，并总结了在每个部位使用 IVUS 可减少手术时间、血管内造影剂剂量、辐射暴露和发病率的证据。最后，讨论了新兴的应用和未来的发展方向。RSNA，2022 年。
