Raised nuchal translucency
Webb20 juli 2015 · Ultrasound measurement of nuchal translucency (NT) thickness is part of first trimester screening for trisomies 13, 18, and 21. 1,2 Increased NT thickness is … An increased nuchal translucency increases the probability that the fetus will be affected by a chromosomal abnormality, congenital cardiac defects, or intrauterine fetal demise. Typically, nuchal translucency alone is not sufficient as a screening test for chromosomal abnormalities. How to define a normal or abnormal nuchal translucency measurement can be difficult. The use of a single millimeter cutoff (such as 2.5 or 3.0 mm) is inappropriate because nuchal translucen…
