Limited Ultrasound


The purpose of the limited ultrasound exam at the Smoky Mountain Pregnancy Care Center is to confirm the presence of a viable pregnancy. Our limited ultrasound exam includes looking for a heartbeat and measuring the gestational age (how far along you are). Our nurses will also be determining the location of the pregnancy (important to ensure you are not experiencing an ectopic pregnancy, a life-threatening concern for mother).

All ultrasounds are completely confidential and provided free of charge. They are performed by nurses certified in limited obstetric ultrasound.

We do not  use limited ultrasound to determine sex. Some restrictions apply, and an ultrasound can only be offered by a nurse.

Following a positive pregnancy test, a limited ultrasound for obstetric verification may be performed to:

Confirm the pregnancy is in the uterus
Detect that a heartbeat is present
Estimate the age of the developing fetus


What is an ultrasound?

Ultrasound comes from a machine that creates an image of the inside of your body. It shows what your baby looks like while still inside your womb (uterus).

An Ultrasound can tell you—and your nurse—many things about your baby, such as:

• the size of the baby
• how well the baby’s heart works
• how well other organs (such as the spine, brain and kidneys) are growing

Our purpose in providing a Limited Ultrasound is that we want to help you verify your pregnancy.

The moving pictures from the ultrasound machine are like a movie. The pictures appear on a computer screen.

How does ultrasound work

Ultrasound pictures are made from sound waves which are too high pitched to be heard by the human ear. The sound waves travel through your skin and are focused on a certain part of your body by a scanning device called a “transducer.” It picks up the sound waves as they bounce back from organs inside the body.

Ultrasound is different from x-rays because it does not use radiation. This makes it safer for you and your baby. Ultrasound is used in many areas of medicine.
