Contrast-enhanced ultrasound (CEUS) is a medical imaging technique that offers multiple advantages over other modalities such as computed tomography (CT) and magnetic resonance imaging (MRI). These advantages include portability, no ionising radiation and no renal toxicity, with the great advantage of real-time imaging. CEUS has numerous established applications for the study of different pathologies, both intravenous and intracavitary administration. The contrast used is different in composition and function from CT or MRI contrast. It is a purely intravascular contrast and, therefore, the enhancement of the lesions may have some differences with respect to CT or MRI in the equilibrium phase. Ultrasound contrast has a very good safety profile, with infrequent, generally mild and immediate adverse reactions in intravascular use and no adverse reactions reported in intracavitary use. It is important to know the basics of contrast-enhanced ultrasound, the different ways to optimise the image and the different artefacts.
超声造影（CEUS）是一种医学成像技术，与计算机断层扫描（CT）和磁共振成像（MRI）等其他方式相比具有多种优势。这些优势包括便携性、无电离辐射和无肾毒性，具有实时成像的巨大优势。CEUS 在研究不同的病理学方面有许多既定的应用，包括静脉内和腔室内给药。所用的造影剂在组成和功能上与 CT 或 MRI 造影剂不同。它是一种纯粹的血管内造影剂，因此，在平衡期病变的增强可能与 CT 或 MRI 有一些差异。超声造影具有非常好的安全性，静脉内使用时不良反应罕见，通常为轻度和即刻，腔室内使用时未报告不良反应。了解超声造影的基础知识、优化图像的不同方法以及不同的伪影非常重要。
