Prenatal ultrasound screening is a medical imaging procedure used during pregnancy to monitor the health and development of the fetus. It employs high-frequency sound waves to create real-time images of the fetus, placenta, and amniotic fluid, allowing healthcare providers to assess the pregnancy’s progress.

Key Purposes of Prenatal Ultrasound:

1. Confirming Pregnancy: Used to verify the presence of a fetus and estimate gestational age.
2. Monitoring Growth: Tracks the baby’s growth, movement, and development over time.
3. Assessing Fetal Anatomy: Screens for any structural abnormalities, including issues with the brain, spine, heart, or other organs.
4. Checking for Multiple Pregnancies: Detects twins, triplets, or more.
5. Evaluating Placenta and Amniotic Fluid: Ensures proper placement of the placenta and checks the amount of amniotic fluid.
6. Determining the Baby’s Position: Identifies if the baby is head-down or in a breech position.
7. Gender Identification: Can be used to determine the baby’s sex, typically after 18-20 weeks.

There are two common types:

• Transabdominal Ultrasound: A probe is placed on the abdomen.
• Transvaginal Ultrasound: A probe is inserted into the vagina, typically in early pregnancy for a clearer image.

Ultrasounds are non-invasive and safe for both the mother and fetus when conducted by trained professionals.
