Patient's question:
A 6-month-old baby cannot lift their head, can roll over, has a normal appetite, and shows no significant abnormalities, but sometimes they shake. What are the ultrasound manifestations of chromosomal abnormalities?Doctor's answer:
Four-dimensional color Doppler ultrasound mainly focuses on a detailed examination of the fetal structural growth and development to identify any abnormalities. It primarily checks for abnormalities in the growth and development of the fetus's limbs, any defects in the external structures, and the growth and development of internal organ structures to identify any malformations. It can also detect defects in the development of the neural tube. Four-dimensional color Doppler ultrasound cannot detect chromosomes. Chromosomes are genetic material and require special examination methods for a definitive diagnosis.
