A Nuchal scan, also known as a nuchal translucency (NT) scan, is a specialized ultrasound examination typically performed during the first trimester of pregnancy, usually between 11 and 14 weeks of gestation. This scan measures the fluid accumulation at the back of the baby's neck, known as nuchal translucency.
