What is the Difference Between a 3D and 4D Ultrasound?

3D and 4D ultrasounds are increasing in popularity. There is one significant difference between a 3D and 4D ultrasound. 3D ultrasounds provide a three-dimensional image and are quite detailed. The doctor can identify the facial features, individual body parts, as well as the gender of the child. With 4D ultrasounds, the machines can go one step further and show actual movement. A 4D ultrasound is more of a short video than several snapshots. The doctor can identify potential problems with certain movements because they can actually watch the child function. Much like the 3D ultrasound, the images are quite clear and provide an accurate depiction of the child's features.

What Does an Ultrasound Tell a Doctor?

Ultrasounds can identify the physical features and attributes of a child while it is still in the mother's womb. A 3D image offers a three-dimensional view that adds depth to the picture. Ultrasounds can detect physical and physiological abnormalities that the parents must prepare for before the child is born. A 4D ultrasound shows movement and will actually let the doctor watch the child move specific body parts to determine if they are functioning as they should. Ultrasounds can also show a child's internal organs and skeletal structure. In most cases, the pictures depict a healthy infant with no problems whatsoever. In the rare instance that a child does have a problem, the ultrasound allows the doctor to address the situation immediately instead of waiting until the child is born.

Are Ultrasounds Safe?

Ultrasounds are considered to be safe for most women. Most doctors offer a disclaimer that repeated ultrasounds may not be healthy for the unborn baby. Ultrasounds involve sending sound waves through the body. As they pass through the tissues, the sound waves can create heat. Over time, this can be hard on the tissues and actually raise the temperature inside the womb. While they may not pose an immediate threat to the baby, it is unknown what will happen if numerous ultrasounds are performed throughout the entire pregnancy. Ultrasounds are non-invasive and require no healing time. There is no damage to the skin and no physical trauma.
