The Euroson 2020 is taking place in Bergen, the gateway to the fjords and mountains of Norway. In accordance with the EFSUMB's motto "Building a European Ultrasound Community", the congress will create a vibrant, interdisciplinary meeting place for students, doctors, engineers, professors, sonographers, industry and all stakeholders of ultrasound. The congress will focus on new developments in science and promote educational activities.

Date: 11th - 13th June 2020
Location: Grieghallen, Bergen, Norway

Safety aspects of ultrasound in prenatal diagnosis

Kai-Sven Heling, Peter Kozlowski
Ultrasound – mechanical vibrations in a medium (mechanical waves) – was designated as non-ionizing radiation in recent years. The term radiation induces anxiety in many pregnant women. Biological effects of mechanical waves (non-ionizing radiation – ultrasound) are dependent on threshold values, while biological effects of electromagnetic waves (X-ray radiation, gamma radiation) are always present regardless of threshold values. A regulation regarding the use of non-ionizing radiation for non-medical purposes was also recently enacted in Germany. Although it primarily does not apply to prenatal diagnosis, § 10 states: "Use of ultrasound in a pregnant person. Fetal exposure must be avoided when using ultrasound for non-medical purposes". This wording has caused renewed uncertainty among both pregnant women and physicians. A huge response was seen on the Internet and on social media. The general sentiment was: "ultrasound is dangerous".

Safety Indices of Ultrasound: Adherence to Recommendationsand Awareness During Routine Obstetric Ultrasound Scanning

Lior Drukker et al.

Automated analysis of prospectively collected data including video recordings of full-length ultrasound scans coupled with operator eye tracking was performed. Using optical recognition, we extracted the Mechanical Index (MI), Thermal Index in soft tissue (TIs), and Thermal Index in bone (TIb) values and ultrasound mode. This allowed us to report the bioeffect safety indices during routine obstetric scans and assess adherence to professional organization recommendations. Eye-tracking analysis allowed us to assess how often operators look at the displayed bioeffect safety indices.


Changes in Liver and Spleen Stiffness by Virtual Touch QuantificationTechnique after Balloon-Occluded Retrograde TransvenousObliteration of Gastric Varices and Exacerbation of EsophagealVarices: A Preliminary Study

Yoshitaka Takuma et al.

To assess liver stiffness (LS) and spleen stiffness (SS) values measured by virtual touch quantification (VTQ) technique in the monitoring of portal pressure and their usefulness for the prediction of the exacerbation of esophageal varices (EV) in patients with gastric varices undergoing balloon-occluded retrograde transvenous obliteration (B-RTO). The LS, SS, and hepatic venous pressure gradient (HVPG) were measured in 20 patients both before and after B-RTO. The change in each parameter between the two groups (EV exacerbation and non-exacerbation groups) was compared by analysis of variance. The efficacy of the parameters for the prediction of the exacerbation of EV was analyzed using a receiver operating characteristic (ROC) curve analysis.
