3-D and 4-D Ultrasound can be damaging to your child. look at British studies on the harmful effects it can have on your child's developing brain because this information has been hushed here in the U.S. it can cause serious brain damage. only use ultrasound when it is absolutely neccesary!!! educate yourself so that you don't hurt your baby.------------------------------in response to the hospital's response... your commercial does suggest making an appointment at will to get a look at the baby growing inside of you. and that is what makes me most alarmed about your advertisement. ultrasounds should only be performed when necessary and only at the levels necessary to see what needs to be seen i completely agree. in other words, nobody needs real time 3-D or 4-D ultrasounds. They are totally unecessary EVERYTIME! which is why we have been using the old standard ultrasound since the 50's. you should change your commercials because you are setting yourself up for a serious law suit to imply people can come to you for dangerously high powered ultrasounds with unecessary risks to our children. i know someone made the decision to spend all this money on that equipment, but you should mention the dangers to your legal dept and see what they have to say about what you are suggesting in your ads. very against just the basics of the hipporatic oath! shame on you!!! do something to change this now!!! anyone getting an ultrasound from this hospital should make a copy of the commercial in case your child winds up with brain damage or one of the many other effects that repeated ultrasounds can cause. if you think it's worth the risk then just have a back up plan in case you are going to need help finding disability services for your child from using these irresponsible machines and the bad doctors that would advise you to do so. >:( and no, nothing that you said helped me besides your admittance that you know that 3-D and 4-D ultrasounds are not safe and not necessary, but I already knew that!
