Pregnancy Ultrasound Scans: Key Information

Viability scans in 1st trimester (10-14 weeks) assess fetal health and detect abnormalities.
Components of a 1st trimester scan include gestational sac, yolk sac, amniotic fluid, CRL measurement, and NT.
2nd trimester (18-22 weeks) fetal anatomy scan checks for anomalies, growth restriction, and fetal anatomy.
Components of a 2nd trimester scan include placental location, BPD & HC, orbits & cerebellum, fetal heart, AC/stomach, cord insertion, urinary bladder, FL, spine, and liquor volume.
Placental location, BPD & HC measurements, orbits, cerebellum, fetal heart, AC/stomach, cord insertion, urinary bladder, FL, spine, and liquor volume are assessed during the 2nd trimester scan.
Late pregnancy scans (29-40 weeks) monitor fetal growth, determine fetus position, and check placenta location.
An amniotic fluid index (AFI) is used to estimate amniotic fluid volume in the uterus.
Normal AFI values range from 5 to 25 cm, with 25 cm considered polyhydramnios.
The AFI measurement technique involves dividing the uterus into four quadrants and measuring the pockets in centimeters.
Fetal Growth and Well Being Scan in the 3rd trimester (28-32 weeks) assesses appropriate growth and fetal health.
3rd trimester scan components include fetal presentation/position, placental position, HC, AC, FL, AFI, and cord Doppler.
A late pregnancy scan is crucial for monitoring fetal growth, determining fetus position, and checking placenta location before delivery.
