One hundred twenty-two images of fetal heads and abdomens were obtained by ultrasound. The head and abdominal circumferences and their ratios were determined by planimetry and by the ellipse method utilizing four different equations. The accuracy of these equations was assessed by regressing the cir
## Abstract Several sources of error associated with the measurement of fetal head and abdominal circumferences (HC, AC) were examined using dynamic image ultrasound. Statistically significant systematic intraobserver errors were not seen unless technical differences in the images were present (HC
Images of 122 fetal heads and abdomens were obtained with ultrasound for the determination of head and abdominal circumferences. The profile shapes were characterized by the cephalic or abdominal index (Dl/D2 x loo), D , and D2 being the
