Ultrasound Contrast-Enhanced Sinogram
22 March 2018 (online)
Introduction Contrast-enhanced ultrasound (CEUS) uses microbubble contrast agents to improve visualization of anatomic structures. Essentially, the contrast agents are tiny bubbles of gas stabilized by a shell, which are very small and, hence, remain in the vascular space. The shell material determines time in circulation and mechanical elasticity, and the gas core determines echogenicity. Using these principles, real-time imaging and subsequent intervention is made easier without the increased risk of radiation. In this exhibit, we discuss the background of CEUS, protocol with ultrasound settings, as well as case examples of its utility in hepatobiliary interventions.

Clinical application of CEUS in hepatobiliary interventions
Learning Points CEUS is a safe way to image organs and different targets without the downsides of ionizing radiation or risk of nephrotoxicity. The possible indications are broad with new applications arising as awareness increases.
