Ultrasound scans internal structures using high-frequency sound waves. The sound waves are generated by a vibrating crystal using a handheld scanner. The reflected sound waves, or ‘echoes’, are then converted into a grainy two-dimensional (or sometimes even three-dimensional) image on the monitor. Ultrasound is used in pregnancy to monitor the baby’s development, and detect any Down syndrome abnormalities. Because the ultrasound scan can’t produce high-quality images, any suspicions of abnormalities should be confirmed by other tests. Although the ultrasound scan can’t be 100% accurate, it is non-invasive and painless. An early pregnancy scan is also a best for your pregnancy time for the best results.
The ultrasound is used in many ways
Ultrasound can be used during pregnancy at several points, including:
- First trimester- An ultrasound is performed during the first three months after conception to confirm that the embryo is growing inside the womb. It also helps to determine the gestational age of the baby and the due date.
- Second trimester- Ultrasound is performed between weeks 18-20 to assess the development of foetus structures like the spine, limbs and brain. It is also possible to determine the size and position of the placenta. Parents can also confirm the baby’s sexual history if they wish.
- Third trimester- An ultrasound is performed at 30 weeks to verify that the baby continues to grow at a normal pace. To ensure that the placenta doesn’t block the cervix, it is examined.
Consider medical issues
Affordable 3D Pregnancy Ultrasound is non-invasive, painless, and safe. Parents often consider ultrasound a way to see their unborn child and maybe discover its sex. The ultrasound is a diagnostic procedure. In some cases, it can indicate that there are abnormalities in the foetus. To confirm the diagnosis, additional tests are often required. Pregnancy Scan is very important for women because it confirms the pregnancy and verifies the fetus is developing as expected.
Transabdominal ultrasound Sound waves travel very well through water. Your full bladder is used by the sonographer to access your uterus. You will need to drink lots of water prior to the test. The sonographer will place you on a table or a bed. The sonographer applies gel to your abdomen in order to make the scanner contact with your skin better. Images are instantly sent to a nearby monitor. Sometimes, the sonographer will need to push very hard to get to the deeper structures. It usually takes around 30 minutes to complete the scan. Vaginal ultrasound Sometimes, transabdominal ultrasounds are not able to produce clear images. For example, air may be too dense in your bowel. Air is a poor conductor and conductor of sound waves. A slender scanner will be inserted into the vagina. The scan takes approximately 30 minutes.
After the ultrasound, immediately follow-up
After the ultrasound is complete, you will be given tissues to remove the gel and can use the bathroom. You will need to schedule an appointment to receive the report from your doctor.
Your 3d fetal ultrasound Perth results will determine what happens next. A normal result does not necessarily mean that your baby is healthy. Some abnormalities cannot be detected using this test. You may need to order additional tests if foetus abnormalities are detected. These tests, which include amniocentesis or chorionic villus sampling, can be optional. Before deciding whether to proceed, discuss the risks and benefits of these tests with your doctor.
There are other types of pregnancy tests
Amniocentesis- A thin needle is inserted through the abdomen to take a small amount amniotic fluid. Ultrasound guides the needle. The fluid sample contains cells which are then tested in a laboratory for any chromosomal abnormalities. One in 250 miscarriage is possible after amniocentesis.
Samples of chorionic villus- To take a small amount of placenta, a thin needle is inserted into the abdomen or cervix. Ultrasound guides the needle. The laboratory then tests the chorionic villi for any chromosomal abnormalities. One in 100 miscarriage is possible after chorionic villus sampling.
