Are you expecting a baby and curious about obstetric ultrasound? At Phoenix Ultrasound, we offer a range of private pregnancy ultrasound and medical scan packages designed to provide you with the best care possible. In this guide, we will explore the essential aspects of these scans to help you understand their importance and how they can benefit you during your pregnancy.
What is Obstetric Ultrasound?
Obstetric ultrasonography is the use of ultrasound technology to evaluate the health of both the mother and unborn baby during pregnancy. This non-invasive technology employs high-frequency sound waves to create images of the developing fetus, the placenta, and other structures within the uterus. Obstetric ultrasound can:
- Detect the baby’s heartbeat
- Determine the baby’s position
- Identify any potential abnormalities or issues
Since its introduction in 1957 in Glasgow, obstetric ultrasound has become a primary diagnostic tool during pregnancy, gaining widespread acceptance and usage over the past 50 years.
The Versatility of Non-Obstetric Ultrasound
While ultrasound is most commonly associated with pregnancy, it is also extensively used for other medical evaluations. Non-obstetric ultrasound can assess various organs and structures within the body. It is used in:
- Gynecology: To evaluate the womb and endometrium.
- Abdominal Imaging: To assess organs such as the liver and gallbladder.
- Musculoskeletal Imaging: To evaluate joints, muscles, and guide steroid injections.
- Vascular and Cardiac Imaging: To examine the heart and blood vessels.
How is Obstetric Ultrasonography Performed?
There are two primary methods for performing obstetric ultrasound scans:
- Transabdominal Ultrasonography: The most common type, where a transducer is placed on the abdomen and moved around to capture images of the developing baby. This method is typically used during the second and third trimesters.
- Transvaginal Ultrasonography: Typically performed early in pregnancy, this method involves inserting a transducer into the vagina to obtain detailed images of the developing fetus. It provides clearer images during the early stages of pregnancy when the fetus is still small.
Indications for Obstetric Ultrasonography
Obstetric ultrasound is crucial for assessing maternal and fetal well-being. It can be part of routine screening at the first prenatal visit or conducted later in pregnancy for specific reasons. Common indications include:
- Dating the Pregnancy: By measuring the crown-rump length to estimate gestational age.
- Assessing Fetal Growth: Monitoring the baby’s growth to ensure it is developing appropriately.
- Detecting Multiple Gestations: Identifying twins or other multiple pregnancies.
- Evaluating the Uterine Cavity: Checking the structure of the uterus.
- Assessing the Placenta and Fluid Volume: Ensuring the placenta is functioning correctly and there is an appropriate amount of amniotic fluid.
- Evaluating the Umbilical Cord: Ensuring the cord is functioning correctly.
- Examining Fetal Anatomy: Checking for any anatomical abnormalities or defects.
- Excluding Ectopic Pregnancy: Confirming that the pregnancy is developing within the uterus.
Ultrasonography also evaluates maternal pelvic organs and structures such as the ovaries and uterus. The NHS recommends at least two scans during pregnancy: one around 12 weeks and another anomaly scan around 20 weeks.
Safety of Obstetric Ultrasonography
There are no known contraindications for obstetric ultrasonography. This means the procedure can be safely performed on anyone, regardless of their medical history or current health condition. It is a non-invasive and painless procedure, making it an ideal tool for monitoring the health of both mother and baby.
Types of Obstetric Ultrasounds
There are three main types of obstetric ultrasound technology:
- 2D Ultrasonography: The most common type, using high-frequency sound waves to create a two-dimensional image of the fetus and placenta. It provides a clear and accurate view of the developing baby.
- 3D and 4D Ultrasonography: These advanced techniques create three-dimensional or four-dimensional images of the developing baby. 3D scans generate a static image, while 4D scans show real-time movement, offering a more detailed view of the baby’s features and movements.
- Doppler Ultrasonography: This technique assesses blood flow in the vessels leading to and from the developing baby, providing important information about the baby’s circulatory system.
Timing for Obstetric Ultrasound
In the UK, the first scan in a normal pregnancy, known as a dating scan, is typically offered by the NHS around week 12. This scan helps to determine the due date and check for any early signs of abnormalities. Pregnancy scans, however, are available from week 5 through private ultrasound providers or the Early Pregnancy Unit (EPU) if an abnormality is suspected. Early scans can provide reassurance and early detection of any potential issues.
Duration of a Pregnancy Ultrasound
A typical pregnancy scan lasts around 10-20 minutes, providing a detailed look at the developing baby. The length of the scan may vary depending on the stage of pregnancy and the specific reason for the scan.
Preparation for an Obstetric Ultrasound
Preparation depends on the gestational age of the pregnancy. For an early pregnancy scan in the first trimester, a full bladder might be necessary to provide a clearer view of the uterus. No preparation is needed for second and third-trimester scans. It is recommended to wear loose clothing that can easily be lifted or removed to expose your abdomen.
Limitations of Pregnancy Scans
In some cases, image quality and diagnostic accuracy might be impaired by the patient’s body habitus or the position of the baby. Despite these limitations, obstetric ultrasound remains a valuable tool for monitoring pregnancy and ensuring the health and well-being of both mother and baby.
