Insights
Stratifying risk in fetal growth restriction (FGR) is complex. Promising methods integrate Doppler ultrasound, biomarkers, modeling, and AI, but require further research for optimal fetal care.
Area of Science:
- Perinatal medicine
- Maternal-fetal medicine
- Diagnostic technologies
Background:
- Fetal growth restriction (FGR) is a clinical finding, not a single diagnosis, associated with significant morbidity.
- Accurate risk stratification is crucial for timely intervention in FGR cases.
- Current methods for identifying at-risk fetuses are diverse and require further validation.
Purpose of the Study:
- To review current approaches for risk stratification in fetal growth restriction (FGR).
- To highlight the potential of integrating multiple data domains for improved FGR management.
- To identify areas requiring further investigation in FGR risk assessment.
Main Methods:
- Review of existing literature on FGR risk stratification methods.
- Analysis of techniques including Doppler ultrasound, maternal biomarkers, multivariable modeling, and artificial intelligence (AI).
- Discussion on the potential benefits of combining data from various domains.
Main Results:
- FGR risk stratification is challenging due to its complex etiology and association with morbidity.
- Multiple domains, including Doppler ultrasound, maternal biomarkers, multivariable modeling, and AI, are being explored to identify at-risk fetuses.
- No single method currently provides definitive risk stratification.
Conclusions:
- Integrating findings from Doppler ultrasound, maternal biomarkers, multivariable modeling, and AI holds promise for advancing FGR risk stratification.
- Further research is necessary to validate and optimize these integrated approaches for clinical application.
- Improved risk stratification will enhance the management and outcomes for fetuses with FGR.
Abstract:
Risk stratification is a core challenge in fetal growth restriction (FGR) care, in part because FGR does not represent a single diagnosis but instead is a finding that is associated with morbidity. Considerable effort has been invested in the development and study of methods to identify fetuses at risk of morbidity and who warrant intervention across multiple domains: Doppler ultrasound, maternal biomarkers, multivariable modeling, and artificial intelligence. It is likely that the most promising advances will integrate findings from across these domains, but further investigation remains necessary.
