Neurosonology Survey in Europe and Beyond

Purpose To provide an overview on education, training, practice requirements, and fields of application of neurosonology in Europe and beyond. Materials and Methods National representatives and experts in neurosonology were surveyed regarding neurosonology requirements and practice in their countries. Descriptive statistics were used to report the data. Results Between February 1 and March 31, 2023, 42/46 (91.3%) national representatives responded to our questionnaire and the completion rate was 100%. Most countries (71.4%) offer a neurosonology training program during neurology residency, but it is part of the undergraduate medical program only in 30.9%. National certification is available in 47.6% of the countries surveyed and most countries (76.2%) require certification to practice. In 50% of the countries, candidates are assessed by a board examination, while in 26.2% they just need to document their practice. There is no formal accreditation of neurosonology centers in 78.6% of the countries surveyed. Only a few require certified personnel and appropriate equipment. Adequate teaching and research activities are only rarely necessary elements for laboratory accreditation. Conclusion Our results indicate that there is a substantial need for transnational harmonization of neurosonological standards to guarantee uniformity and quality of performance. This survey will also provide guidance to promote an international accrediting council and create a quality-controlled laboratory network for implementing neurosonology in clinical trials.
