Can 2D color Doppler ultrasound exclude fetal malformations?

Patient's question:

I got married last year. Recently, I've been experiencing lower abdominal pain, especially during my period. I'm very worried about it affecting fertility, and I also feel extremely cold and afraid of the cold. Can a 2D color ultrasound rule out fetal abnormalities?

Doctor's answer:

The diagnostic scope of 2D color Doppler ultrasound is not very broad, and it generally cannot detect all abnormalities.
Advice: If there was no medication taken in early pregnancy and no family history of genetic disorders, it is unlikely to cause fetal abnormalities. There is no need to be overly anxious. In fact, you can also consider undergoing a 3D color Doppler ultrasound examination. This only requires visiting a local regular maternal and child health care hospital to apply for a prenatal health card and regularly follow the requirements to complete the prenatal check-ups.
