Ultrasound technology is used to monitor pregnancy and fetal development. It provides expectant parents and healthcare providers insights into the development and growth of the fetus throughout pregnancy. Ultrasounds are used in comprehensive prenatal care, are non-invasive, and are a part of diagnostic measures for complications.
How Ultrasounds Work
Ultrasound, or sonography, is a non-invasive medical imaging method that uses high-frequency sound waves to create real-time images. These waves pass through the body and bounce off tissues, fluids, and bones. The reflected sound waves are then captured and processed by a computer to create detailed images of the uterus and fetus.
During pregnancy, it is used to monitor the developing fetus. The procedure is safe and painless, as it uses sound waves rather than radiation. There are various types of ultrasounds tailored to specific needs during pregnancy.
Types of Ultrasound
The procedure is performed using a device called a transducer, which emits sound waves. Transabdominal ultrasounds move the transducer across the abdomen to capture images. Transvaginal ultrasounds insert a transducer into the vagina to get a closer view early in pregnancy.
Other specialized scans include Doppler ultrasounds, which measure fetal blood flow, and 3D or 4D ultrasounds, which provide more detailed images of the fetus. Ultrasounds are typically conducted by trained sonographers or medical professionals and reviewed by a healthcare provider to assess the images.
Ultrasound Monitoring
Ultrasound monitoring is a common but informative part of prenatal care. It allows healthcare professionals to track fetal development and detect potential complications early. Aspects of ultrasound monitoring include their use in regular monitoring, fetal growth, and early detection of fetal abnormalities.
Regular Monitoring
Regular ultrasounds are scheduled during pregnancy to monitor the health and progress of both the mother and fetus. Typical milestones in ultrasound appointments include:
- First Trimester (6–12 weeks): An ultrasound confirms pregnancy, estimates gestational age, and detects the fetal heartbeat.
- Second Trimester (18–22 weeks): A detailed anomaly scan assesses fetal anatomy, growth, and development. The baby’s sex may also determined.
- Third Trimester (28–40 weeks): Additional ultrasounds may be performed to monitor amniotic fluid levels and fetal position.
These visits provide information to guide decisions on prenatal care and delivery planning.
Fetal Measurements
Ultrasounds observe fetal growth by taking measurements of anatomical structures. Crown-Rump Length (CRL) in early pregnancy estimates gestational age. Head Circumference (HC) and Abdominal Circumference (AC) assess growth. The length of long bones, like the femur, is used to estimate size.
This data helps healthcare providers determine if the fetus is growing at a healthy and expected rate. If growth abnormalities, such as intrauterine growth restriction (IUGR) or macrosomia (a significantly larger size), are detected, additional evaluations or interventions may follow.
Fetal Complications
Ultrasound technology identifies and diagnoses various fetal and pregnancy-related complications. Some of these include placenta-related issues, structural abnormalities, amniotic fluid disorders, and fetal positions that could complicate delivery. Early detection of such complications found with regular monitoring allows healthcare providers to make appropriate medical decisions.
