Normal Late first trimester ultrasound survey A Normal Late First Trimester Ultrasound Survey typically occurs between 11 to 13.6 weeks of gestation. It is an important diagnostic tool that assesses fetal development and screens for potential abnormalities. The key components of a normal survey during this stage include: Fetal Structures Assessed in the Late First Trimester (11w to 13w 6d) 1– Structures of neutral Positions of the Fetus 2– Cranial Structures 3–Facial Structures 4–Neck Structures 5–Thoracic Structures 6–Abdominal Structures 7–Limbs and Extremities 8–Spine 9–Genitourinary System 10– Placenta 11–Umbilical Cord 12– Amniotic Fluid Assessment 13– Maternal Anatomy Assessment 1. Structures of neutral Positions of the Fetus
A neutral position in fetal ultrasound refers to a standardized orientation of specific anatomical structures to ensure accurate measurement and assessment. This position is essential for reducing variability in measurements, particularly during the late first trimester.
The fetal head should be in a neutral or slightly flexed position, neither excessively flexed (chin too close to the chest) nor hyperextended (head tilted backward).
