Pregnancy Ultrasound Scan
An ultrasound scan is frequently offered to women that are pregnant at about 12-14 weeks. In certain conditions, for example, if there aren't any particular risks or issues, you may be able in have earlier or later scans if needed.
How they work
An Ultrasound works by transmits silent sound waves through the body tissues to create an image of your baby in your womb, which you and your partner will be able to see on a TV/computer screen.
Before having your trans abdominal scan, you'll be asked to drink lots of fluid rather than to empty your urinary bladder! If your urinary bladder is complete, it then pushes up from your uterus to provide a better perspective of your infant. This is really important in the very first 50% of pregnancy.
When you are lying down, a gel is going to be put on your lower abdomen and a hand held probe/scanner/transducer will be moved in various directions on the skin to allow you to visualise your infant in your womb.
Ultrasound scans may also be carried out utilizing a vaginal probe. If this is true, you'll not typically need to have a full urinary bladder since these sorts of ultrasound scans provide a clearer image, particularly in early pregnancy ultrasound.
While the scan is been carried out, the sonographer will usually explains what she/he is looking at, and you may be given a black and white print of the image to take home with you, as well as a written ultrasound report.
Some units even gives you the option to get your bay scan recorded on a video tape, which you can buy.
Do ultrasound scans hurt?
Ultrasound scans are completely painless, and also to date there is no medical evidence to prove that they can harm either pregnant woman or her unborn baby.
