This produces a 3D image, and the added detail makes it easier to see smaller structures, such as fingers and toes, as well as facial features.Ī 4D ultrasound sends sound waves across multiple planes, with numerous waves per second. In most cases, however, they are accurate - particularly if a skilled doctor analyzes the images and does a follow-up scan.ģD and 4D scans offer greater detail than traditional 2D ultrasound images.Ī 3D ultrasound works by sending sound waves from multiple angles. Ultrasounds cannot detect all pregnancy complications, and they may even suggest issues that are not there. Instead, a doctor will meet with the woman shortly afterward to go over the results. If an ultrasound technician performs the scan, they may not be able to answer questions. the health of the woman and the pregnancy, which may involve looking for signs of problems such as placenta accreta and placenta previa and measuring fluid levels.the fetus’s sex, to see whether the genitals are developing in the usual way.for some congenital disabilities and some early signs of developmental issues.the fetus’s organs, organ systems, and structures, including the brain, skull, heart, face, bones, hands, and feet.the number of fetuses, if this is the first ultrasound of the pregnancy.This may cause pressure, but it should not be painful.Ī 22-week ultrasound to check on the anatomy of the fetus may last about an hour.ĭuring the anatomy scan, the healthcare provider will check: This involves placing a thin transducer into the vagina.

They then use a handheld tool called a transducer to generate sound waves, and gently move the tool around the abdomen while checking the relayed images on a monitor.įor the best images, it may help to have a full bladder, which helps the sound waves to travel more effectively.Ī vaginal ultrasound may offer a better image, especially when the fetus is in a certain position.
The healthcare provider, possibly a technician, applies gel to the woman’s bare abdomen. Processĭuring an ultrasound, the pregnant woman lies on a table. The most common type is a 2D ultrasound, which offers a simple, somewhat grainy black and white image. The scan is not a photo and cannot capture every detail. An ultrasound scan during pregnancy involves sound waves bouncing off of the fetus and structures in the body to create a rough picture.
