I had my 20 week scan today with Dr Lam - 31F, Henley building on Queens Road Central. I think you need to be referred by a Dr. It cost $2000 and was 3D or even 4D - amazing!!! I had my last child in London on the NHS and never experienced anything like this with a 12 week ultrasound. Dr Lam and his assistant spend about 20 minutes or more ... they check everything - the nose, each nostrils, eye sockets, that the lips are separated, the ears, heart, kidneys, fingers, toes, sex organs (we closed our eyes for this as we do not want to know the gender) ... the clinic I believe is the only or one of only in HK ... he goes to the top of the head and you can actually see inside the brain with all 4 chambers, when he checks the heart and you can see the 4 chambers clearly and the size of the major vein and aorta. They give you several pictures and a DVD.
