With the increasing availability of contrast-enhanced US (CEUS) worldwide and in the United States, the potential applications of this modality in abdominal imaging and intervention are continuing to expand. CEUS leverages the many inherent benefits of US with a safe and unique microbubble contrast agent. When injected intravenously, US contrast agents (UCAs) function as a pure blood pool agent, augmenting diagnostic US examinations such as vascular imaging. In the procedure suite, UCA can be used to improve needle visualization and depict active extravasation. UCA may also be injected through needles and tubes into various body spaces, allowing the assessment of the urinary system, indwelling catheters, and other tracts and cavities. Some venous and lymphatic lesions may be diagnosed with the direct injection of a UCA into these lesions. The authors highlight some of the many applications that are relevant to the abdominal imaging professional and interventional radiologist but should not be considered a complete list, and users of UCAs should continue to consider uses beyond those traditionally highlighted in recent literature.

随着对比增强超声（CEUS）在全球和美国的应用越来越广泛，该技术在腹部成像和介入治疗中的潜在应用不断扩大。CEUS 利用了超声的许多固有优势，并结合了安全且独特的微泡造影剂。静脉内注射超声造影剂（UCAs）后，其可作为纯血池造影剂，增强血管成像等诊断性超声检查。在手术室内，UCA 可用于提高针的可视性并描绘出活跃的外渗。UCA 也可以通过针和管注入到各种体腔中，从而评估泌尿系统、留置导管和其他管道和腔隙。一些静脉和淋巴病变可通过直接向这些病变内注射 UCA 来诊断。作者强调了一些与腹部成像专业人员和介入放射科医生相关的许多应用，但不应将其视为完整列表，而且 UCAs 的使用者应继续考虑超出近期文献中传统强调的用途。RSNA，2022 年。
