title: Ultrasound contrast harmonic imaging of abdominal organs.
abstract: Ultrasound contrast agents consist of microbubbles, which are the most effective acoustic backscatters. The interaction between the insonating ultrasound beam and the microbubbles is very complex and basic understanding of their behavior under various sound fields has been fundamental to the development of improved methods of visualizing and displaying the contrast agents. Although echo enhancers have been under development for a long time, their clinical applications have been limited to enhancing the Doppler signals in difficult cases. However, recent advances in harmonic imaging and the development of new tissue-specific contrast agents stand to broaden the scope of ultrasound diagnostic potential beyond simply rescuing failed Doppler examinations. This article reviews the current and potential applications of ultrasound contrast harmonic imaging in the abdomen.
