Introduction to Fetal Ultrasound Imaging
- Fetal ultrasound has revolutionized fetal medicine over the past four decades, becoming the primary modality for initial assessment of fetal health and development.
- Provides normative biometric data including measurements such as head circumference, biparietal diameter, and ventricular size.
Technological Advancements in Fetal Ultrasound
- Significant improvements in imaging quality through the development of high-frequency, three-dimensional (3D) transducers.
- Transvaginal ultrasound has addressed limitations inherent in transabdominal approaches, such as maternal obesity and early gestational assessments.
- Doppler ultrasound has enhanced capabilities to evaluate fetal cerebral and cardiovascular circulation, crucial for diagnosing fetal hypoxemia and cardiovascular anomalies (Baschat et al. 2001; Donofrio et al. 2003).
