Ultrasound Facts and Information

What is the difference between an ultrasound and a sonogram?

An ultrasound is the machine that allows you to see your baby during your pregnancy. A sonogram is the picture taken of your baby during the ultrasound. A sonogram is a "still-shot" of your baby.  4D Ultrasounds take 3D ultrasound images, or 3D sonograms, and adds the element of time to the process. The result: Live Action ultrasound images of your baby. Some people refer to the procedure as prenatal imaging, 3D imaging, a 3D scan, or 4D scan.

What Is the Difference Between 2D, 3D and 4D Ultrasound?

One of the most wonder occasions for expectant moms and dads is the very first time they view their unborn child through the use of ultrasound. In years past, the screen images were dark and hard for the inexperienced eye to decipher. In recent years, 3D and 4D ultrasound has  become widely available to parents who desire a more detailed image of their child.

Prenatal sonography is the utilization of high frequency sound waves which travel into the womb via a transducer to generate images of the baby. A 2D sonogram is the procedure that most women have during their prenatal care from a doctor that produces black and white 2D ultrasound pictures. This kind of ultrasound is usually used to listen to the babies heartbeat and identify gender. It can also help a doctor determine how far along the pregnancy is as well as look at any potential birth defects. It is usually conducted at 20 weeks to allow the doctor to ensure the overall health of the placenta, and that the baby is developing as expected. Around this time, it's usually possible to deterine gender, assuming the baby cooperates and is in a good position!

3D ultrasound produces a clear, detailed image.  4D Ultrasound is accomplished by basically viewing the 3D images in succession.

Sonography has been used since the 1950s. Just like 2D ultrasound, 3D/4D ultrasound does not use radiation such  an with an xray.  It uses strictly sound waves.

3D/4D ultrasounds are available in some doctor's offices, but tend to be optional services offered by specialty boutiques. As a result, 3D/4D ultrasounds from boutiques are not paid for by insurance.  According to most ultrasound centers, the best time to have a 3D/4D ultrasound is between 24-36 weeks.

A large number of ultrasound locations allow and encourage you to bring friends and family to share the 3D 4D ultrasound experience.  It's a great bonding time for the whole family.
