Table 1. Uses of contrast-enhanced ultrasound in ultrasound-guided interventional radiology procedures.
Abstract

Although not necessary for the vast majority of ultrasound-guided procedures, intravenous contrast agents can be useful for procedures aimed at lesions that require contrast enhancement to be seen on ultrasonography.

Using contrast-enhanced ultrasonography to guide procedures has two drawbacks: first, because enhancement from ultrasound contrast agents is short lived, it is often necessary to plan several injections; second, because the needle is poorly seen on contrast-enhanced ultrasonography, a dual image display format is necessary.

Contrast-enhanced ultrasonography can be used for planning and monitoring diagnostic and therapeutic procedures, for guiding the procedures, and for follow-up. Using contrast-enhanced ultrasonography enables better results in both types of procedures; moreover, it can be used within cavities.

Resumen

Aunque el contraste intravenoso no es necesario en la inmensa mayoría de los procedimientos realizados con guía ecográfica, su uso puede permitir realizar procedimientos en aquellas lesiones que solo se visualizan con ecografía con contraste.

Los problemas que tiene son dos: el tiempo limitado del realce producido por el contraste, que requiere con frecuencia planificar varias inyecciones, y la mala visualización de la aguja, que requiere el uso de doble ventana de visualización.

Puede ser usada en la planificación y el control de los procedimientos diagnósticos y terapéuticos, tanto en la guía del procedimiento, para monitorizar el alcance del tratamiento, como en los controles posteriores. Su uso permite mejorar los resultados de ambos tipos de procedimientos. Puede ser usada también intracavitariamente.
