Normative range for MRI amniotic fluid volume from 16 to 36 gestational weeks: Absolute and relative values, and correlation to ultrasound

Key Points

To establish MRI-based normative charts for amniotic fluid volume and its ratio with fetal body volume during gestation.
Developed normative charts for amniotic fluid volume (AFV) and AFV/fetal body volume (FBV) ratio.
Analyzed data from 16 to 36 weeks of gestation.
Compared MRI findings with ultrasound measurements.
Established first normative MRI charts for AFV and AFV/FBV ratio.
Provided reference ranges that may aid in clinical decision-making.
Showed a correlation between MRI and ultrasound measurements of amniotic fluid.

Abstract

This study provides the first MRI-based normative charts for AFV and AFV/FBV ratio between 16 and 36 weeks' gestation. The AFV/FBV ratio represents a novel physiological marker integrating fetal growth and fluid balance. These reference ranges may support future research and clinical decision-making.
