The best time for a successful 4D scan is between 26 to 30 weeks of pregnancy. Despite this, from our experience beautiful images may still be captured out with these gestations, however there would be a higher risk of not obtaining all the desirable images to complete the chosen package. Between the optimum gestation of 26-30 weeks, your baby will be developed enough to give an accurate view of the characteristics of his/her face. At this gestation there is plenty of fluid around your baby to allow for fetal movement and provide a ‘window’ to see your baby. 4D scanning can be done before or after this gestation, depending upon individual circumstances. If you book outside of our recommended stage of 26 – 30 weeks, we don’t offer a rescan if we can’t obtain good images at the first appointment. Please speak to one of our trained staff for further information.
