Insights
Updated guidelines provide international recommendations for using contrast-enhanced ultrasound (CEUS) in liver applications. These guidelines clarify contrast agent differences and handling for improved patient management.
Area of Science:
- Medical Imaging
- Hepatology
- Radiology
Background:
- The European Federation of Societies for Ultrasound in Medicine and Biology first issued guidelines for hepatic contrast-enhanced ultrasound in 2004.
- Previous guideline updates addressed changes in contrast agents and expanded to non-hepatic applications.
- The 2012 guidelines required updating due to imprecise descriptions of contrast agents, phases, and handling, and the emergence of new evidence.
Purpose of the Study:
- To present the fourth iteration of recommendations for the hepatic use of contrast-enhanced ultrasound (CEUS).
- To update guidelines based on new evidence, recent developments in contrast agents, and international experience.
- To establish standard international protocols for UCAs in liver applications to enhance patient management.
Main Methods:
- Review and synthesis of the latest scientific evidence on contrast agents for ultrasound.
- Incorporation of recent developments, including FDA approvals and Asian clinical experience.
- Development of updated recommendations for the hepatic use of ultrasound contrast agents (UCAs).
Main Results:
- The updated guidelines provide a clear distinction between different contrast agents.
- Recommendations now include precise details on contrast phases and handling procedures.
- The guidelines reflect an international perspective, incorporating global data and experiences.
Conclusions:
- These updated guidelines offer a comprehensive framework for the international use of UCAs in liver applications.
- Standardized protocols aim to improve diagnostic accuracy and patient care in hepatic imaging.
- The document serves as a crucial resource for clinicians utilizing CEUS in liver disease management.
Abstract:
The present, updated document describes the fourth iteration of recommendations for the hepatic use of contrast-enhanced ultrasound, first initiated in 2004 by the European Federation of Societies for Ultrasound in Medicine and Biology. The previous updated editions of the guidelines reflected changes in the available contrast agents and updated the guidelines not only for hepatic but also for non-hepatic applications. The 2012 guideline requires updating as, previously, the differences in the contrast agents were not precisely described and the differences in contrast phases as well as handling were not clearly indicated. In addition, more evidence has been published for all contrast agents. The update also reflects the most recent developments in contrast agents, including U.S. Food and Drug Administration approval and the extensive Asian experience, to produce a truly international perspective. These guidelines and recommendations provide general advice on the use of ultrasound contrast agents (UCAs) and are intended to create standard protocols for the use and administration of UCAs in liver applications on an international basis to improve the management of patients.

Ultrasound I: Abdominal Ultrasonography
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...
