Expected = 0.0033 × GA^2.86.

When to use

Congenital diaphragmatic hernia, thoracic masses or oligohydramnios when fetal lung growth matters.

How it works

Expected TFLV (mL) = 0.0033 × GA^2.86; o/e TFLV = observed / expected.

Key points

  • Expected = 0.0033 × GA^2.86.
  • <25% severe.
  • 25–35% moderate.
  • Liver herniation adds risk.

FAQ

Frequently asked questions

What are the limits and cautions when using Fetal MRI Lung Volume o/e TFLV (CDH Assessment)?
For licensed clinicians and clinical researchers. Interpret results with history, investigations and local protocols; not a diagnosis or prescription, and not a substitute for multidisciplinary decision-making or local guidelines.
Does Fetal MRI Lung Volume o/e TFLV (CDH Assessment) upload patient data? Where is it calculated?
Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
How is Fetal MRI Lung Volume o/e TFLV (CDH Assessment) calculated in practice? Can you show a worked example?
Inputs: Gestational age 30 weeks, Total fetal lung volume (MRI segmentation) 18 mL, CDH side Right, Liver herniation No → Result: o/e TFLV 32.5%（Expected TFLV: 55.3 mL = 0.0033 × GA^2.86 (30.0 wk), o/e TFLV: 32.5%, Band (CDH literature): 25–35%: moderate）
