“…Pelvic diameter increased every 20 days of pregnancy and had a better correlation with gestational period and the average correlation with other parameters was greater than (R 2 <0.90). Interischial distance measurement had strong correlation with gestational age in pregnant women using ultrasonography (Al-Esawi et al, 2016). The pH of fetal fluid was reduced steadily and there was a negative correlation between pH in fluid and other parameters.…”

This study aimed to determine values of ewe's fetal developmental parameters and their correlations during pregnancy. The study carried out on eighteen variable parameters of 64 pregnant ewes collected from Duhok slaughterhouse. The average correlation of genital tract weight, crown to rump, head, thoracic, pelvic, orbital diameters, forelimbs, humerus, hind limb, Tibia, Occipito-nasal and greater length of skull were high (>0.90). The umbilical cord circumferences, interorbital, fetal weight, and hoof length were moderately correlated (>0.80) with other parameters. Potential hydrogen (pH) of embryonic fluid had a negative correlation with other parameters. Fetal age, crown-rump length, thoracic, and fetal head diameters increased every 10 days. Genital tract weight, interorbital, and occipitonasal length increased every 20 to 30 days. However, length of skull was increased only during late pregnancy. The forelimb and hindlimb increased slightly with pregnancy development. Caruncle and umbilical cord diameters were increased during the half term of pregnancy then reduce or remain in the same diameters at the end. Embryonic fluid pH turns to acidity with fetal development. In conclusion, specific parameters are practical to confirm gestational age during specific gestational period when the date of breeding is unknown.

“…Since Jaffe et al 5 used pelvic ultrasound to estimate GA, few studies have been done on this subject 6 . Although the pelvis is involved in skeletal dysplasia and several fetal anomalies, almost no quick and simple method has been reported for measurement of pelvic bones in routine ultrasound imaging because the complex anatomy of the pelvis makes it challenging to find standard criteria for ultrasound measurement of pelvic bones 7,8 .…”

Objectives There has been a dearth of an accurate and reliable method for the measurement of fetal pelvic bones. In this study, we describe a novel, easy‐to‐use method for ischial and iliac bone measurement in fetal ultrasound scanning. Methods This prospective cross‐sectional study was performed on 1179 pregnant women at 12 to 40 weeks of an uneventful gestation. Pelvic biometric indices, including the length of the ilium and ischium, were measured by a novel and easy method. Then data were analyzed by regression models to develop a formula for gestational age (GA) estimation based on pelvic bones. Results The approximate ossification time of the ischium was determined to range between the 13th and 20th gestational weeks. We calculated 3 formulas using linear regression models: formula 1, GA (days) = 92.563 + (11.604 × ischial length); formula 2, GA (days) = 57.006 + (7.819 × iliac length); and formula 3, GA (days) = 65.809 + (5.610 × iliac length) + (3.431 × ischial length). Conclusions The 2‐dash line method can contribute to efficient and precise ultrasound measurement of the ilium and ischium in pelvic biometry of the fetus.
