“…Various pulsing schemes exist that are designed specifically for suppressing tissue while detecting bubble echoes [25,26]. Those are Pulse Inversion, Power Modulation, Power Modulated Pulse Inversion (also known as Cadence Pulse Sequencing), as well as some non-linear matched filtering schemes (such as FM chirps).…”

Dynamic Contrast Enhanced Ultrasound (DCE-US) is an imaging technique that utilizes microbubble contrast agents in diagnostic ultrasound. The EFSUMB guidelines published in 2004, updated in 2008 and 2011 focused on the use of DCE-US, including essential technical requirements, training, investigational procedures and steps, guidance on image interpretation, established and recommended clinical indications and safety considerations. However the quantification of images acquired with ultrasound contrast agents (UCAs) is not discussed in the guidelines. The purpose of this EFSUMB document is to provide some recommendations and descriptions of the quantification of ultrasound images, technical requirements for analysis of time-intensity curves (TICs), methodology for data analysis, and interpretation of the results.

Ultrasound contrast is gaining acceptance worldwide as an adjunct to conventional ultrasound imaging. It has clinical applications as diverse as liver disease detection and characterization, myocardial perfusion and wall motion studies, and imaging of cerebral vascularity and perfusion. This paper will focus on imaging techniques used for transcranial ultrasound contrast imaging. The interaction of ultrasound with the microbubbles in the contrast agent is complex and nonlinear. This has led to the development of a variety of imaging modes to improve contrast detection compared with non-contrast optimized modes. This article presents several of these imaging methods in such a way as to help users of ultrasound contrast in the clinic and in research to understand this rapidly developing field.

“…However, a simple explanation of a pulse sequence is given in Figure . The following review is recommended for a detailed discussion of the various pulse sequences . Low MI contrast‐specific techniques allow dynamic real‐time continuous evaluation during the three vascular phases for all UCAs .…”

With the recent Food and Drug Administration approval of Lumason (sulfur hexafluoride lipid-type A microsphere, Bracco Diagnostics Inc, Monroe Township, NJ) for contrast-enhanced ultrasound (CEUS) to characterize focal liver lesions in both adult and pediatric patients, widespread use of CEUS is expected in the United States. This paper provides guidance in setting up a CEUS program, and reviews the practical details that will need to be instituted in a standard ultrasound department to provide both safe and efficient use of CEUS. A review of the indications, contraindications, adverse events, instructions for performing the exam, and image interpretation are discussed.
