A 4D baby scan is an ultrasound scan, but unlike your conventional 2D black and white ultrasound scan which you may have seen at the hospital, the 4D scan produces life like images so that you can actually see what your baby looks like. You can have the 4D baby scan between the 22nd and 34th week of pregnancy although we suggest you try to book between your 28th week and your 32nd week.

Generally we would suggest doing the 4D scan slightly later at around weeks gestation if you have a high BMI. All of our scans require extra time if you are expecting twins. The charge for your scan is the same as it is for a singleton, however you need to advise us at the time of your booking so that we can allow the extra time for your appointment. When you arrive for your scan we will ask you to complete a short registration form to include your pregnancy dates and contact details.
