Regarding lUGR:
Abdominal circumference is the most accurate measurement to predict IUGR. AC below 10th centile is used as a cutoff. AC should increase by at least 10mm in 2 weeks. AC is measured preferably at the level of the junction of the left and right poal veins,umbilical vein and as round as possible. TEXTBOOK OF OBSTETRICS, Sheila Balakrishnan,2nd edition, page no.205
Abdominal circumference (AC) is the least sensitive parameter for detection of lUGR
In asymmetric lUGR head circumference/abdominal circumference (HC/AC) is reduced
Serial biparietal diameter (BPD) is the only impoant measurement in lUGR
Abdominal circumference is the most accurate measurement
