It also acts as a protective barrier against infections and maintains pregnancy by producing key hormones. As the first organ to reflect pathological changes during pregnancy, placental evaluation can aid in the early detection of pregnancy complications. The primary objective of this study was to assess the correlation between placental thickness (PT) and fetal biometric parameters during the second-trimester anomaly screening, aiming to facilitate earlier detection of pregnancy outcomes.</p><p><strong>Materials and methods: </strong>This cross-sectional study included 300 healthy pregnant women with gestational ages between 18 and 22 weeks, determined by last menstrual period or first-trimester ultrasound.
