The Nuchal Translucency (NT) scan is a non-invasive ultrasound done between 11 and 14 weeks of pregnancy. It measures the fluid at the back of the baby’s neck to screen for chromosomal abnormalities like Down syndrome and assess overall fetal development. Early detection means early reassurance and care, making this scan a crucial step in your pregnancy journey. Expecting parents often have questions—and that’s completely normal.
