The Definition of 3D Ultrasounds
3D ultrasound is a newer technology that is changing the way ultrasounds are used. 3D ultrasound can be used for other purposes, but its major use is for fetal screening. Ultrasound boutiques are popping up all over the country offering a way for expectant parents to view their baby before it arrives. However, 3D ultrasound is not just for entertainment, there are great advantages in using 3D sonograms for screening, particularly for obstetrics.

Defintion
-
A 3D ultrasound uses sound waves just as a 2D ultrasound does, but instead of transmitting the waves straight though the tissue and organs and back again, it is emitted in various angles--causing a three-dimensional view. A 2D ultrasound is a flat image and a 3D ultrasound shows depth, contour and detail.
3D/4D
-
A 3D ultrasound is the groundwork for a 4D ultrasound. 4D shows movement using a compilation of 3D images. Movements like heart motion and yawning can be seen in real time.
-
Elective vs. Diagnostic
-
An elective ultrasound is a keepsake sonogram where the patient can see the baby in 3D and obtain pictures or even video. A diagnostic ultrasound is used to detect abnormalities in the fetus or mother.
Benefits
-
A 3D ultrasound can show fetal anomalies that otherwise would not be detected. Heart valve abnormalities, cleft lip and club foot can be diagnosed before the baby is born.
Risks
-
Ultrasound poses no significant risk since radiation is not used. However, patients are not encouraged to have serial sonograms.
