[Diagnostic sonography in obstetrics and gynecology]

Obstetric and gynecological ultrasound has become one of the most important first-line diagnostic modalities in contemporary clinical practice, playing a central role in antenatal care, prenatal screening and gynecological diagnostics. The aim of this review is to provide a comprehensive overview of the development of obstetric and gynecological ultrasound in Hungary, its current national guideline framework and its integration into international standards, with particular emphasis on technological innovations and quality assurance. The article analyzes the position and relevance of Hungarian recommendations in comparison with major international guidelines, including those of ISUOG, FMF, ESHRE and the IOTA consortium, and summarizes the main clinical indications of ultrasound in obstetrics and gynecology. Special attention is given to the role of 3D/4D imaging, Doppler techniques, structured reporting and artificial intelligence-based decision support systems, which contribute significantly to improved diagnostic accuracy and reproducibility. The strengths of the Hungarian system include wide accessibility, guideline-based practice and a license-based training and competency framework. Future challenges involve further development of education, enhancement of auditability and the integration of data-driven and artificial intelligence-supported solutions into routine clinical workflows. The responsible and standardized use of modern ultrasound technology remains essential for patient safety, quality assurance and evidence-based clinical decision-making.
