text: The examination is usually carried out by scanning through the abdomen but if the pregnancy is very early, scanning via a probe inserted into the vagina may be appropriate (transvaginal ultrasound).This scan is of value to any woman who may have concerns about her pregnancy, who is unsure of how far along she is or simply wishes to see the pregnancy progressing.The best time to do a 3/4D scan is between 26 and 32weeks.It is difficult to influence the baby’s position but time is set aside to allow the baby to wake and move around if necessary.
  The baby's wellbeing is assessed by examining the amount of fluid around the baby and the function of he placenta ('afterbirth') using a technique called Doppler ultrasound.
