Okay, so we have lots of measurements taken in millimetres.
Each measurement is shown on a graph which has a line down the middle indicating the 'average' point. A dot either side of the line indicates whether the measurements fall above or below the average (but still within a normal range).
Fluff-bucket's 'normo-gram' measurements are as follows:
- Skull/head measurements x 3 (BPD 57mm, OFD 73.3mm, HC204.7mm) - all above average.
- Transcerebellar Diameter (TCD) - 22.6mm - average. (The measurement correlates almost exactly with gestational age and is used to help determine gestational age more accurately.)
- Cisterna Magna (this is a tricky one to figure out ... I think it can indicate brain abnormalities if measuring over 10mm) - 6.4mm - slightly above average.
- Nuchal Fold Thickness - 4.9mm (I believe anything under 6mm is considered normal).
- Abdominal Diameter and Circumference measurements x 3 ( TAD 55mm, APAD 49.6mm, AC 164mm) - all average. (These measurements can help determine the baby's weight).
- Femur Length (FL) - 37.7mm - slightly above average.
- Estimated Fetal Weight (AC/FL) - 451g (1lb) - average. (Apparently there is a correlation between the Femur Length and the Abdominal Circumeference that helps determine the baby's weight.)
