High tech ultrasound

Samm

Were any of you sent out for a high tech ultrasound for your 20 week anatomy scan? I’m wondering what the difference is and why they recommended that for you. My first quad blood screening cane back concerning for downs, but luckily my second test (councyl- the more accurate one) came back negative, which brought me relief! My doctor still wants me to see the genetic counselor and do the high tech ultrasound though.
