Patient's question:
Currently pregnant with my second child at 24 weeks + 4. My first child was born via vaginal delivery on December 10, 2014, a healthy boy. At 12 weeks of pregnancy, I underwent a detailed NT scan, which was normal. At 24 weeks + 4, I had a 4D ultrasound, which revealed a strong light point in the left ventricle of the fetus, but the heart itself is normal. During this period, I missed the triple screen. By combining the results of the detailed NT scan and the 4D ultrasound, can we predict the chromosomal status of the fetus?Doctor's answer:
First, don't be nervous. This is a common clinical diagnosis, and it doesn't necessarily mean the child has a problem. But you asked if NT and MRI can predict the fetal chromosomal condition. The answer is no. NT is a screening test. For example, if your NT is 1mm, it means you are at low risk, and you should focus on a normal early pregnancy. Later, the ultrasound also indicated the presence of a nasal bone (it is believed that the absence or shortness of the nasal bone may be abnormal).
