Abstract.

h: 0px; "> Objective: ultrasound in estimating the Gestational Age (GA) compared to GA by Naegele’s rule using Last menstrual period (LMP) date.

Materials and Methods:
spontaneously conceived viable singleton pregnancy, a regular menstrual cycles, andspontaneous onset of labor at term. The fetuses (894 and used for statistical analysis. We used Deviation (SD), Median and Percentiles values (3rd, 5th, 10th, 50th, 90th, 95th, and 97th) measurements on gestational age. We found a regression equation to estimate the GA using CRL measurements. The results of the current study were compared with different studies using the Paired Differences (t Results: 0.151 (CRL)
The Mean Sum of Squares of regression deviations of the GA regression model using (CRL) was 1546.8 0.67 and 18-22), Conclusion: measurements in a group of pregnant Syrian women. These results can be useful in women who cannot recall their last menstrual period (LMP). Ou estimating gestational age and fetal care. A larger study might be
the population This research aimed to determine the efficacy of Crown Rump Length (CRL) by This was a prospective observational study of women with a normal LMP was considered certain in all cases. We used ultrasound to scan 2067 healthy women) and we had 500CRL measurements Descriptive Statistics to calculate the Mean, Standard
-test analysis). The results were represented as tables & diagrams. The best-fit equation for the estimate of GA Yi 
from CRL (in mm) was: i – 9.5*10-4(CRL)i2 + 4.12*10-6(CRL)i3 and this value is significant at P <0.001. The standard error of the Estimate (Std.Error)was the standard deviation (SD)was (0.65, 0.71, 0.69) weeks respectively. In this study, we presented diagrams and tables for the estimation of GA using CRL r criteria will provide useful needed to include a larger sample of . Data were collected prospectively for CRL Yi  = 6.254 + when the GA were (≤12, 12-18, references for estimating gestational age and fetal care. A larger study might be the population. needed to include a larger sample
