Prototype Memory-Guided Training-Free Anomaly Classification and Localization in Prenatal Ultrasound
arXiv:2607.00744v1 Announce Type: cross Abstract: Prenatal anomaly classification and localization is of critical importance for fetal health and pregnancy management. Although ultrasound (US) is the primary modality for prenatal screening, accurate diagnosis remains challenging due to the low prevalence and high heterogeneity of anomalies. Existing deep learning methods for prenatal tasks rely on large-scale annotated datasets, which are difficult to obtain in practice. Although few-shot learning alleviates data scarcity, it typically requires fine-tuning for new categories, limiting its prac
Advances in AI, particularly in areas like few-shot learning and memory-guided techniques, are reaching a maturity that allows for their application in challenging, data-scarce domains like prenatal diagnostics.
This research provides a pathway for AI to deliver critical medical diagnostic capabilities in areas where traditional deep learning is hampered by limited annotated datasets, addressing a significant bottleneck in healthcare AI.
The ability to perform anomaly classification and localization in prenatal ultrasound with minimal data and without constant fine-tuning for new categories makes advanced diagnostics more accessible and scalable.

Improved early detection of fetal anomalies leads to better pregnancy management and health outcomes.
Reduced healthcare costs associated with late diagnosis and more complex interventions could be realized.
The methodology could be generalized to other rare disease diagnoses, profoundly impacting medical fields beyond obstetrics.
