Ultrasound (US) is undoubtedly a crucial modality for paediatric Radiology, with inherent advantages including lack of ionizing radiation, good patient tolerability and widespread availability. Nevertheless, there are clinical settings where it cannot fully address the clinical inquiry, for example in focal liver lesion characterization or confident assessment of tissue perfusion or ischemia. Computed tomography (CT) and Magnetic Resonance (MR) Imaging are then performed as a second step modality to further assess suspicious US findings, with both imaging modalities with inherent disadvantages. CT imaging is associated...

General presentation of data An online database was created by the EFSUMB, where different institutions from Europe and across the World can contribute cases where CEUS was performed in paediatric patients. The database is online-based within the website of EFSUMB (https://www.efsumb.org/blog/) and can be accessed using the following link: http://www.efsumb-data.org/v1/login.asp. After a brief authorization process, each registered physician can contribute cases and data. Information requested is categorized in different types and includes demographic data (age, gender), indication for CEUS (organ examined, type of pathology, past...

Paediatric CEUS is safe and useful in many paediatric applications involving most organs of the human body. Only a small number of side effects have been recorded in this large database of paediatric CEUS examinations, while a large variety of indications have been reported, covering a wide spectrum of paediatric pathology. Physicians are strongly encouraged to contribute cases to the EFSUMB Paediatric CEUS Registry, allowing the body of evidence to accumulate. In this way, the Registry can be useful in detecting adverse reactions to ultrasound...
