Contrast media have gained acceptance to enhance ultrasonography in many fields of medicine; in particular, cardiology. Several agents have been described and many more are being manufactured and tested. By increasing the number of strong sound scatterers, these agents improve images by increasing the amount of echoes. This is true both for grey-scale and color or Doppler imaging. Their use in obstetrics is very limited at the moment because of safety issues. In a laboratory setup, they have been shown to markedly enhance placental imaging. In gynecology, imaging of the uterine cavity and Fallopian tubes is greatly improved. A potential area where ultrasound contrast may find a role is gynecological oncology. Vascularity is increased in many tumors, but usually vessel diameter is small and velocity low. One can therefore expect future use of the ultrasound contrast agents in ovarian or other gynecological neoplasms.
在医学的许多领域，尤其是心脏病学领域，造影剂已被广泛应用于增强超声检查。目前已经描述了多种造影剂，并且有更多的造影剂正在被生产和测试。通过增加强回声散射体的数量，这些造影剂通过增加回波量来改善图像。这在灰阶成像以及彩色或多普勒成像中均适用。由于安全问题，目前它们在产科的应用非常有限。在实验室环境中，已证明它们能显著增强胎盘成像。在妇科领域，子宫腔和输卵管的成像有了很大改善。超声造影可能发挥作用的一个潜在领域是妇科肿瘤学。许多肿瘤的血管增多，但通常血管直径小且流速低。因此，可以预期超声造影剂在卵巢或其他妇科肿瘤中将有未来的应用。
