NT ultrasound question

Hey girls, just a quick question for you that have had the NT ultrasound. Did the doctor tell you the results of the ultrasound that day or did you have to wait until the blood work came back? We lost our 2nd little one at 20 weeks due to a huge cystic hygroma, fetal hydrops and a heart defect that was all found at our 20 week ultrasound. We go Tuesday for an NT scan to check for any of these issues. Just hoping I'll know if this baby is healthy as soon as possible!
