Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
| Gestational age | 30 weeks |
|---|---|
| Total fetal lung volume (MRI segmentation) | 18 mL |
| CDH side | Right |
| Liver herniation | No |

Common questions
What is Fetal MRI Lung Volume o/e TFLV (CDH Assessment)?
Compare fetal MRI total lung volume with the Rypens expected value to get o/e TFLV for CDH hypoplasia stratification. Instant, browser-side.
How is Fetal MRI Lung Volume o/e TFLV (CDH Assessment) calculated? What is the core formula?
Expected TFLV (mL) = 0.0033 × GA^2.86; o/e TFLV = observed / expected.
When is Fetal MRI Lung Volume o/e TFLV (CDH Assessment) used?
Congenital diaphragmatic hernia, thoracic masses or oligohydramnios when fetal lung growth matters.
What are the key clinical points for Fetal MRI Lung Volume o/e TFLV (CDH Assessment)?
Expected = 0.0033 × GA^2.86. <25% severe. 25–35% moderate. Liver herniation adds risk.
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）
