Flashcards

First Trimester Ultrasound (6-8 weeks)

Confirms pregnancy presence, location, and multiple pregnancies. Checks fetal heartbeat and gestational age.

Nuchal Translucency (NT) Screening (11-14 weeks)

Measures nuchal translucency to assess risk of chromosomal abnormalities, like Down syndrome; checks baby's overall development.

High NT measurement (>3.5mm)

Indicates possible increased risk for chromosomal abnormalities and potential problems like heart defects.

Detailed Ultrasound (18-22 weeks)

Detailed scan checking baby's organs (brain, heart, kidneys, spine), placenta, amniotic fluid and growth.

Study Notes

Ultrasound Check-ups During Pregnancy

First Trimester (Weeks 1-12)
- First Ultrasound (6-8 Weeks): Confirms intrauterine pregnancy, checks for multiples, detects fetal heartbeat, and confirms gestational age.
- Nuchal Translucency (NT) Screening (11-14 Weeks): Measures nuchal translucency to assess risk of chromosomal abnormalities (like Down syndrome). Also checks baby's overall development. NT measurement above 3.5 mm may indicate increased risk of chromosomal abnormalities (Down syndrome, Trisomy 18, heart defects).
Second Trimester (Weeks 13-26)
- Detailed (Second-Level) Ultrasound (18-22 Weeks): Examines baby's organs for structural abnormalities (brain, heart, kidneys, spine), placenta position, amniotic fluid, and overall growth.
- Anatomical Scan (Around Week 20): Thorough check of baby's anatomy and organ development to detect congenital abnormalities, crucial for early detection of developmental issues.
