Best parameter for ultrasound evaluation of IUGR is:
Placental membrane
Length of femur
Abdominal circumference
BPD
“Abdominal circumfernece (AC) is the single most sensitive parameter to detect IUGR. Serial measurements of AC and estimations of fetal weight are more diagnostic to fetal growth restriction.”

“The biometric parameters, AC is most affected by fetal growth”
