Hello all,
I am 12 weeks
pregnant. I had my NT scan which shows NT 0.8 mm but nasal bone non ossified. I have done by T21 1:2683, T13/18 1:29000 tests which shows low risk.
Could please suggest is it a cause of concern that nasal bone is non ossified. All other things pre maxillary triangle, three vessels chord, ductus venosus flow,stomach bubble are seen and normal
