Contrast-Enhanced Endoscopic Ultrasound

Abstract

Endoscopic ultrasonography (EUS) has been widely used to assess tumors of the gastrointestinal tract as well as lymph nodes. However, EUS has its limitations in differentiating benign from malignant tumors. Microbubble imaging has allowed the observation of the vasculature of the abdominal organs on transabdominal US. Second-generation US contrast agents produce harmonic signals at lower acoustic powers that are suitable for EUS imaging and may help differentiate tumor types. This chapter reviews the current indications and limitations of this novel imaging and its potential future applications.
