“Comparison the Amniotic Fluid Index (AFI) Obtained with Gray-Scale Ultrasound and Color Doppler”

Abstract

This cross sectional study was done to find out the correlation between gray scale & color Doppler sonographic finding of amniotic fluid index, in the department of Radiology & Imaging, Mymensingh Medical College & Hospital from July 2012 to June 2014. Total 120 pregnant women ages in between 18-40 yrs with gestational age between 28 to 40 weeks from OPD or indoor patient was purposively selected. Statistical analysis was done by using SPSS version 20 windows & the significant differences were measured by paired t test & Kappa test for evaluation of AFI in both gray scale & color Doppler Ultrasonography findings. The mean AFI in case of gray scale was 12±4.6 cm (mean±SD) varied from 3.7-38 cm & 10.2±4.4 cm (mean±SD) varied from 2.6-35 cm measured by color Doppler. The mean difference was 1.8±1.2 cm varied from 0-10 cm. The mean AFI was significantly higher (p< 0.05) in gray scale. The level of agreement in 75.8% and comparison of the results shows significant but reliable difference between two modalities. Also a significant positive correlation (r=0.915, p<0.001) was found. So color Doppler Ultrasonography also enhances the detection of oligohydramnios and help in the management of high risk pregnancy.
