Assessment of Gestational Age Using Ultrasound
Author(s): G Rajathi*
Abstract
Determining gestational age in resource-poor settings is challenging because of limited availability of ultrasound technology and late first presentation to antenatal clinic. Last menstrual period (LMP), symphysio-pubis fundal height (SFH) and Ballard Score (BS) at delivery are therefore often used. This study explains the relationship between MSD, CRL and GA (USG) in the first trimester, BPD, HC, AC, FL and GA (USG) in the second trimester, EFW, BPD, HC, AC, FL and GA(USG) in the third trimester. From the results 3D and 4D USG will improvise the ability to assess early pregnancy viability and multiple gestations.
