Obstetric ultrasound
Obstetric ultrasound in nagpur is sometimes called a prenatal ultrasound. It is a non-invasive imaging procedure that progresses to view the fetus and placenta in the course of pregnancy. It uses high-frequency sound waves to create images of internal structures and organs of the fetus.
Obstetric ultrasounds are used for several purposes:
1. Confirmation of pregnancy and detection of fetal heartbeat
2. Determination of the age of the fetus and due date
3. OBSERVATION of development and growth of the fetus
4. Detection of any congenital anomalies or abnormalities
5. Monitor fetal well-being and activity
What is Obstetric Ultrasound?
It’s an imaging method that does not penetrate the body with high-frequency sound waves, providing images of the fetus and placenta; this is also known as prenatal ultrasound.
Purpose of Obstetric Ultrasound
– Confirmation of pregnancy and presence of fetal heartbeat
– Assessment of fetal age and due date
– Assessment of growth or development of the fetus
– Detection of congenital anomalies or abnormalities
– Monitoring of fetal well-being and movement
– Guiding prenatal care and delivery decisions
– Detection of multiple pregnancies (twins, triplets etc.)
– Assess placenta position and activity
– Track amounts of amniotic fluid
Varieties of Obstetric Ultrasound
– Abdominal ultrasound (TAU)
– Vaginal ultrasound (TVU)
– Doppler ultrasound
– 3D and 4D ultrasound
– Fetal echocardiography (fetal heart ultrasound)
When is Obstetric Ultrasound Performed?
Usually between 6 to 10 weeks for a first scan
Scan every 4-6 weeks later
Perform more scans in case there are special concerns or problems that arise
Benefits of Obstetric Ultrasound
– It is totally pain-free and safe
– Non-invasive
– No radiation
– Allows real-time diagnosis
– Highly cost effective compared to other imaging modalities
– Portable and accessible in most health centers
Limitations of Obstetric Ultrasound
– Dependence on the size and composition of maternal body for image quality
– Failure to detect all congenital anomalies or abnormalities
– Depth penetration is poor so it cannot image deep structures.
What Is a Obstetric ultrasound?
An obstetric ultrasound, or prenatol ultrasound is a technique applied in visualizing the placenta and fetus in pregnancy without invading it. It applies high-frequency sound waves to provide images of the internal structures or organs within the fetus and determines what stage of gestation they are at and their due dates as well as knowledge on aspects of fetal growth, development, congenital anomalies, or abnormalities.
– Fetal surveillance and activity
– Counseling for antepartum care and intrapartum decisions
– Diagnosis of multiple pregnancy (twins, triples, etc.)
– Placental position and function assessment
– Amount of amniotic fluid
Obstetric ultrasound is a painless, non-invasive, and accessible image test that is helpful in the management for a healthy continuation and outcome of pregnancy.
What procedures Obstetric ultrasound?
Obstetric Ultrasound procedures consist of:
1. Dating Ultrasound (6-10 weeks): Confirms pregnancy, dates it and evaluates fetal maturity.
2. Nuchal Translucency Scan (11-14 weeks): Delineates the foetal neck area’s thickness to establish chromosomal abnormalities.
3. Anatomy Scan (16-20 weeks): Analytic anatomic examination of the foetus consists of all the organs and limbs.
4. Growth Scan (24-40 weeks): just monitoring their growth in size.
5. Doppler Ultrasound at 12 weeks: The blood flow of the umbilical cord and fetal vessels is assessed.
6. Biophysical Profile (BPP) at 24 weeks: This evaluates fetal well-being based on movement, tone, and amniotic fluid.
7. Fetal Echocardiography at 16 weeks: Fetal echocardiography focuses on the detailed structural and functional analysis of the fetal heart.
8. Trans-vaginal Ultrasound (TVU) in early pregnancy: Used for a more detailed imaging of the fetus and the placenta.
9. 3D and 4D Ultrasound (abdominal ultrasound, at or after 16 weeks) Detailed features of the fetus and his movements can be visualized.
10. Evaluation for Fetal Growth Restriction (FGR) at or after 24 weeks assessment of fetal growth and wellbeing in cases of suspected growth restriction.
Note: procedures and timing are individualized based on circumstances and healthcare provider recommendations.
