Dr. Deepti Agarwal, an Expert Consultant Radiologist at GMS Mangal Clinic and Diagnostics, Dehradun, emphasizes the importance of the NT & NB scan—a vital prenatal screening performed between 11 to 14 weeks of pregnancy. The Nuchal Translucency (NT) scan helps assess the risk of chromosomal abnormalities such as Down’s syndrome, while the Nasal Bone (NB) assessment adds further diagnostic accuracy. Detecting an overly thick nuchal fold or absence of the nasal bone can serve as key early markers for certain genetic conditions. Early and accurate screening under expert radiological care ensures better prenatal health and peace of mind for expecting mothers.
