“ASSESSMENT OF FETAL GESTATIONAL AGE WITH FETAL DESCENDING COLON DIAMETER IN THIRD TRIMESTER AND ITS CORRELATION WITH OTHER FETAL BIOMETRIC PARAMETERS”

Abstract

Accurately determining gestational age is pivotal for safe antenatal care, benefiting both mother and fetus by guiding
screening tests, labor induction, and assessments. While clinicians previously relied on history and physical exams,
ultrasound now predominates due to irregular menstrual cycles. The first trimester is optimal for ultrasound-based
dating, yet accuracy diminishes in the third trimester, with a ±2-week standard deviation after 34 weeks. Thus,
there's an need to develop new ultrasound indices for precise gestational age determination in later stages, ensuring
optimal care throughout pregnancy.
