The 3D images can also be captured and saved for later review. ![]() ![]() But the 3D image allows the doctor to see width, height, and depth of images, which can be helpful in diagnosis. This technique, which provides a three-dimensional picture, requires a special machine and special training. If more information is needed, a 3D ultrasound examination can be performed. This gives a flat picture of one aspect of the image. The most common is two dimensional, or 2D. There are several types of ultrasound imaging techniques.

To assist in prenatal tests such as an amniocentesis To determine the number of fetuses and examine the placental structures Mid-trimester: (sometimes called the 18 to 20 week scan) In some cases to detect fetal abnormalities To examine the uterus and other pelvic anatomy To diagnose an ectopic pregnancy or miscarriage To determine the number of fetuses and identify placental structures Ultrasounds may be performed at various times throughout pregnancy for different reasons: A screening ultrasound is sometimes done during the course of a pregnancy to monitor normal fetal growth and verify the due date. Ultrasound in Pregnancy What is an ultrasound?Īn ultrasound scan is a diagnostic technique which uses high-frequency sound waves to create an image of the internal organs. ![]()
