What is the difference between 3D and 2D ultrasound?

Ultrasound uses high -frequency sound waves to create an image of the unborn child in the womb, but the resulting photo tends to look different depending on whether it is two -dimensional (2D) or three -dimensional (3D). The standard is 2D ultrasound, which is often the one that pays health insurance because it can be considered medically necessary. Doctors often order at least one two -dimensional ultrasound during pregnancy to make sure the measurement is correct for the gestational age, even if it can also be used to determine the sex of the child and whether it shows any abnormalities. 3D ultrasound is usually considered optional because its main function is to offer parents a clearer image of their unborn child. In general, 2D ultrasound is often used for medical purposes, while 3D ultrasound creates a monument for parents.

early in pregnancy, doctors sometimes perform 2D ultrasound that makes sure the childIt has a heart rhythm and determines the age of pregnancy to identify the maturity date. This type of ultrasound can also be used sometime during the second trimester, usually about 20 weeks. It is sense when the technician measures unborn organs and limbs to ensure that they are all normal, and at the same time ensure that the umbilical cord is healthy. If they see any abnormalities, the patient can be handed over for further testing. For this reason, 2D ultrasound is often considered necessary during pregnancy and is usually paid by health insurance, at least in the United States.

In some cases, 2D ultrasound is considered an optional test. For example, the child's sex is not a requirement during pregnancy, but many parents want to do it. In many cases, this can be done during the required ultrasound around 20 weeks. However, if defining the characteristics at that time cannot be clearly identified, the parents are often responsible for paying for another visit if they are determined to find out sex. In addition to tOho may have to apply in addition to the use of 2D ultrasound to perform deep tests, which are not considered necessary, such as determining the chances of the child for certain genetic conditions.

Almost all 3D ultrasounds are considered optional, so parents let them pay for them, often at a boutique medical clinic rather than in a doctor. This technology sends sound waves from several directions that offer a fuller picture of the child. Unlike 2D ultrasound, the child's face features can often be seen clearly using 3D technology, especially between 24 and 36 weeks. Many medical abnormalities are not clearly visible with this type of ultrasound, but the result is often a clear photo of the fetus that parents can treat as a child's first picture, which is in photography.
