Score of Cannie et al for Predicting Fetal Body Volume Based on Gestational Age

 

Patient selection: gestational age from 100 to 260 days

 

Parameters:

(1) gestational age in days

 

predicted fetal body volume in mL =

= (0.0698 * ((gestational age)^2)) – (5.3597 * (gestational age)) – 428.5

 

Performance:

• The presence of growth retardation or macrosomy would result in observed volumes much different from that predicted.

• The gestational age must be accurate for an accurate prediction.
