In this series of papers on comments and illustrations of the World Federation for Medicine and Biology (WFUMB) guidelines on contrast enhanced ultrasound (CEUS) the topics of non-infectious and non-neoplastic focal liver lesions (FLL) are discussed. Improved detection and characterization of common FLL are the main topics of these guidelines but detailed and illustrating information is missing. The focus in this paper is on non-infectious and non-neoplastic FLL and their appearance on B-mode, Doppler ultrasound and CEUS features. Knowledge of these data should help to raise awareness of these rarer findings, to think of these clinical pictures in the corresponding clinical situation, to interpret the ultrasound images correctly and thus to initiate the appropriate diagnostic and therapeutic steps in time.

"How to perform contrast-enhanced ultrasound (CEUS)" provides general advice on the use of ultrasound contrast agents (UCAs) for clinical decision-making and reviews technical parameters for optimal CEUS performance. CEUS techniques vary between centers, therefore, experts from EFSUMB, WFUMB and from the CEUS LI-RADS working group created a discussion forum to standardize the CEUS examination technique according to published evidence and best personal experience. The goal is to standardise the use and administration of UCAs to facilitate correct diagnoses and ultimately to improve the management and outcomes of patients.
RESUMO
Ultrasound examination of the kidneys with grey-scale imaging and colour Doppler ultrasound is the most common renal imaging modality. A few years ago, contrast-enhanced ultrasound (CEUS) emerged as a non-invasive perfusion imaging modality to evaluate the renal vessels and microvascularisation. These contrast media contain intravenous microbubbles (sulfur hexafluoride), which have no deleterious effect on renal function. Being free of iodine, they also pose no risk for the thyroid gland. CEUS of the kidneys is mainly used for the evaluation of renal cysts and the analysis of renal lesions suspicious for malignancy. Also this method is used to visualise inflammation as well as renal perfusion after trauma or infarction.

Initially, a set of guidelines for the use of ultrasound contrast agents was published in 2004 dealing only with liver applications. A second edition of the guidelines in 2008 reflected changes in the available contrast agents and updated the guidelines for the liver, as well as implementing some non-liver applications. Time has moved on, and the need for international guidelines on the use of CEUS in the liver has become apparent. The present document describes the third iteration of recommendations for the hepatic use of contrast enhanced ultrasound (CEUS) using contrast specific imaging techniques. This joint WFUMB-EFSUMB initiative has implicated experts from major leading ultrasound societies worldwide. These liver CEUS guidelines are simultaneously published in the official journals of both organizing federations (i.e., Ultrasound in Medicine and Biology for WFUMB and Ultraschall in der Medizin/European Journal of Ultrasound for EFSUMB). These guidelines and recommendations provide general advice on the use of all currently clinically available ultrasound contrast agents (UCA). They are intended to create standard protocols for the use and administration of UCA in liver applications on an international basis and improve the management of patients worldwide.
