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.
