Ultrasonography in Pregnancy Show What is an ultrasound scan?An ultrasound scan involves transmitting high frequency sound waves through the uterus. These bounce off the baby and the returning echoes (sound waves) are translated by a computer into an image on a screen that reveals the baby’s position and movements. Why do I need an ultrasound scan?Ultrasound has been used in pregnancy for about 30 years, it has progressively become an indispensable obstetric tool and plays an important role in the care of every pregnant woman. The common reasons for your doctor to request an pregnancy ultrasound scan are:• To establish the date when the baby is due. Who will do the scan?Scans are usually performed by a doctors, midwives or radiographers who are specially trained in ultrasound, and are known as sonographers. Most have completed a post graduate Certificate, Diploma or Master’s degree in Medical Ultrasound. When scans are usually carried out in antenatal period?The JIJAI WOMEN’S HOSPITAL Provide ultrasound screening for pregnant women and fetuses at risk for pregnancy-related complications by offering diagnostic ultrasound scans to detect fetal and placental abnormalities throughout pregnancy. Your first-trimester ultrasound, commonly performed to evaluate the risk of genetic abnormalities, has allowed for the early detection of some major abnormalities before the second trimester. The range of fetal ultrasonography services include: Five, six or seven weeks: NUCHAL TRANSLUCENCY SCAN (11-14 wks) 10 to 14 weeks: About 18 – 20 weeks: Colour Doppler Scan (About 28-32 wks): Why Is Doppler Ultrasound Used During Pregnancy?There are various diagnostic uses for Doppler Ultrasound in a traditional medical setting, but in terms of pregnancy and fetal and pregnancy health, uses are limited. Doctors often use Doppler Ultrasound during pregnancy to check fetal umbilical blood flow, placental blood flow and blood flow in the heart and brain. Using the Doppler Ultrasound results, doctors can determine if restricted blood flow due to sickle cell anemia, RH sensitization or restricted blood vessels is to blame for fetal abnormalities. Restricted blood flow to the fetus could cause:• Lower birth weight If sickle cell anemia is diagnosed, children may undergo a special form of Doppler Ultrasound known as the Transcranial Doppler to evaluate risk of stroke. 28 to 40 weeks:Growth scans in the third trimester may be recommended if a previous baby was small, if you are having twins or when there are other complications of pregnancy, for instance if you are diabetic. Sometimes your midwife may suggest a growth scan if the baby feels and measures smaller or larger than expected. A scan maybe ordered when an abnormality is suspected on clinical grounds. Otherwise a scan is generally booked in the first trimester to confirm pregnancy, exclude ectopic or molar pregnancies, confirm cardiac pulsation and measure the crown to rump length for dating. What to expect from a3D Scan?You will receive at least four colour portrait prints, and at least two black and white portrait prints. These portrait prints are further complemented with between 10-20 colour images on CD, suitable for emailing and printing to share with all the family. In addition, throughout the whole scan, a DVD is recorded of any movement the baby makes. When to have a 3D Scan?While there is no problem performing the 3D scan at any stage of your pregnancy, in order to get the best images, we perform the 3d scan between 22 and 32 weeks of pregnancy, although we advise that the optimum time is between 24 and 29 weeks. The timing of the scan is really a balancing act, as you want baby to be as big as possible so you get to see as much as you can, but you still want your baby to have plenty of room to move around. The 3D Scan / 4D scan is optional and does not replace your maternity hospital scan, as it is not intended to provide diagnostic information but to enhance parental enjoyment and bonding. Which uses high frequency sound waves to make an image of a developing fetus?An ultrasound is a diagnostic or screening procedure that uses high-frequency sound waves to create a picture of internal body structures, such as a developing fetus. It may also be called an ultrasound scan, sonogram, or ultrasonography.
Does high frequency sound affect fetus?Increased noise levels can cause stress. This can cause changes in a the body that can affect your developing baby. Sound can travel through your body and reach your baby. Very loud noises may be able to damage your baby's hearing.
What is the process in which high frequency sound waves can the mother's womb?An ultrasound uses high-frequency sound waves to create an image of a developing baby, the mother's placenta, and uterus, usually during the second trimester.
What uses sound waves to detect the health and development of the fetus?A fetal ultrasound (sonogram) is an imaging technique that uses sound waves to produce images of a fetus in the uterus. Fetal ultrasound images can help your health care provider evaluate your baby's growth and development and monitor your pregnancy.
