Obstetrical Ultrasounds in Miami, FL
What is a Fetal Ultrasound?
- A safe, painless and non-invasive test
- Used to confirm a pregnancy and its location
- Used to determine how a pregnancy is progressing, the baby’s growth rate, age and sex.
- Used to determine location and development of the placenta
- Identifies possible fetal abnormalities
A fetal ultrasound provides you and your doctor with a first glimpse of your developing baby. An ultrasound produces a picture of the baby to monitor the size and position of the fetus and check for problems. This type of imaging is non-invasive and uses sound waves to produce an image. Ultrasound results may estimate the due date, check for multiple pregnancies, and find major birth defects. No radiation is used, so there is no risk for you or the baby.
All ultrasounds are produced using sound waves that are delivered to a specified area of the body and then bounce back to a transmitting device that converts the length of the sound waves to create a detailed image of the patient’s internal structures. This type of technology is extremely useful in the diagnosis of many medical conditions, or in this case, to routinely check in on the development of a fetus.
Types of Ultrasounds
There are special types of ultrasounds that are used to view different things. Learn more about the different types and when they are used below.
The standard type of ultrasound used during these routine visits to South Florida Women’s Care are known as a transabdominal fetal ultrasound. This means that the procedure is performed in the abdominal area.
During your transabdominal fetal ultrasound, a technician will apply a gel to the belly and begin moving a device called a transducer back and forth across the area. Images created by the sound waves bouncing back to the transducer will be visible on a screen in front of you and the technician.
Often times if a patient is having a fetal ultrasound performed during the early stages of her pregnancy, a transvaginal ultrasound will be used. This type of fetal ultrasound requires a probe to be inserted through the vagina, which helps to create clearer, more detailed images of the baby.
3D and 4D Fetal Ultrasounds
Most fetal ultrasound imaging tests will only produce a static 2D image for patients to view. However, recent technologies have allowed for more defined images to be created that can give a 3D, or even a 4D rendering of the developing fetus.
3D ultrasound images allow your obstetrician to assess the height, length, and width of the baby, while also showing them more detailed images of the patient’s reproductive system as well. A 4D ultrasound has these same capabilities, but also has the added benefit of producing a moving video of the fetus.
Other Fetal Examinations
There are a number of other techniques and tests that can evaluate more specific aspects of a growing baby’s health, including the analysis of their blood flow, heart function, facial structure, and more. Such tests are typically only conducted if your OBGYN suspects there may be a problem during your baby’s development, and so they are not implemented for every patient. These additional ultrasound imaging tests include:
- Doppler ultrasound
- Fetal echocardiography
- Specialized sonographic evaluation
The Purpose of a Fetal Ultrasound
Generally, when a woman reaches the 18th week of her pregnancy it will be time to conduct an ultrasound. As mentioned, this diagnostic procedure is used to assess the ongoing growth and development of the fetus. More specifically, fetal ultrasounds are used to:
- Confirm a pregnancy
- Determine the number of babies in the womb
- Monitor amniotic fluid levels
- Study the condition of the placenta
- Determine the baby’s gender
- See where the fetus is located and how it is positioned
- Investigate potential birth defects
- Evaluate how quickly the fetus is growing
- Diagnose possible complications with the pregnancy
Not all of these evaluations will be available during the first few weeks of a woman’s pregnancy. This is why patients are expected to return to South Florida Women’s Care every few weeks to complete another ultrasound and to address any changes in fetal development.
How to Prepare for Your Ultrasound
- Wear comfortable, loose-fitting clothing.
- Most likely the test needs to be done with a full bladder. For transvaginal ultrasound or those in late pregnancy, a full bladder usually isn’t necessary.
What to Expect During Your Ultrasound
- The examination usually takes less than 30 minutes.
- The patient is usually positioned on an examination table and clear gel is applied to the abdomen. This improves conduction of sound waves and eliminates air between the transducer, a small plastic device that sends out sound waves and records them as they bounce back, and your skin.
- The transducer moves back and forth over the abdomen, directing sound waves into the uterus and capturing the reflected sounds waves that are digitally converted into images.
