Question:My NT scan showed absent nasal bone. Is this a high risk marker for down syndrome. NT measurements was normal. Has anyone done through this. Please help
Answer: Hi dear, so if nasal bone is absent but other measurements are normal then further scan is required like double marker and triple marker to check the growth and other measurements. Only then anything can be said. But don't stress out just relax and stay positive everything will be fine.
Question:Nasal bone is 3.2mm during NT scan...is it normal???
Answer: Hello, I'm happy to help. Yes it's normal. The measurement between 2.5mm and 3.5mm is completely normal. As the NT increases, so does the risk of Down's and other chromosomal abnormalities. Take care.
