SONOGRAPHY 4D
What is Sonography?
In ultrasonography, or ultrasound, high-frequency sound waves, inaudible to the human ear, are transmitted through body tissues. The echoes are recorded and transformed into video or photographic images.
3D and 4D ultrasounds are optional.
What the Test Does
Like regular ultrasounds, 3D and 4D ultrasounds use sound waves to create an image of your baby in your womb. What’s different is that 3D ultrasounds create a three-dimensional image of your baby, while 4D ultrasounds create a live video effect, like a movie — you can watch your baby smile or yawn.
Sonography Room
Parents often want 3D and 4D ultrasounds. They let you see your baby’s face for the first time. Some doctors like 3D and 4D ultrasounds because they can show certain birth defects, such as cleft palate, that might not show up on a standard ultrasound.
On the day of the test
- It is very important to arrive with a full bladder. This allows the technologists and radiologist to view the bladder while it is full and after it has been emptied.
- Your ultrasound test is performed by registered, expert radiologists.
- You may be asked to change into a hospital gown.
How the Test Is Done
For an abdominal ultrasound, you’ll lie down and a technician will put a certain gel on your belly. This helps carry the sound waves. Then the radiologist will hold a probe against your belly and move it around to get an image.
