First trimester ultrasound is performed in the first months of a pregnancy. Pregnancy ultrasounds are performed mainly using transabdominal ultrasound. For many women, especially after 8 weeks gestation, sufficient information about the baby may be obtained with transabdominal ultrasound only. However, in the early pregnancy, the developing embryo is very small at 6 weeks gestation, the baby is only mm long and a transvaginal ultrasound may be required to get a better image of the baby.
Transvaginal ultrasound is safe and commonly performed during all stages of pregnancy, including the first trimester. It will not harm you or your baby. Transabdominal ultrasound involves scanning through your lower abdomen. A small amount of ultrasound gel is put on the skin of the lower abdomen, with the ultrasound probe then scanning through this gel. The gel helps improve contact between the probe and your skin. Transvaginal ultrasound is an internal ultrasound.
It involves scanning with the ultrasound probe lying in the vagina. Transvaginal ultrasound usually produces better and clearer images of the female pelvic organs including the developing pregnancy, because the ultrasound probe lies closer to these structures. The transvaginal ultrasound probe is thin, about 2cm diameter.

History of Technology Heroes and Villains – A little light reading Here you will find a brief history of technology. Initially inspired by the development of batteries, it covers technology in general and includes some interesting little known, or long forgotten, facts as well as a few myths about the development of technology, the science behind it, the context in which it occurred and the deeds of the many personalities, eccentrics and charlatans involved. You may find the Search Engine , the Technology Timeline or the Hall of Fame quicker if you are looking for something or somebody in particular.
Scroll down and see what treasures you can discover. Background We think of a battery today as a source of portable power, but it is no exaggeration to say that the battery is one of the most important inventions in the history of mankind. Volta’s pile was at first a technical curiosity but this new electrochemical phenomenon very quickly opened the door to new branches of both physics and chemistry and a myriad of discoveries, inventions and applications.
The electronics, computers and communications industries, power engineering and much of the chemical industry of today were founded on discoveries made possible by the battery.

Can the scan show the gender of my baby? What is actually done? Scans are usually performed by a doctors, midwives or radiographers who are specially trained in ultrasound, and are known as sonographers. The whole pregnancy will be assessed. The amount of liquor amniotic fluid , the position and appearance of the placenta and a detailed scan of the baby itself. The baby will be measured, and the anatomy examined in detail.
It is recommended that all pregnant women have a scan in the first trimester at around 12 weeks of pregnancy to confirm their dates. First trimester ultrasonic scans may show ‘soft’ markers for chromosomal abnormalities, such as an increased fetal nuchal translucency back of the neck to enable detection of Down’s syndrome fetuses. When is the nuchal fold screening test carried out?
The test is performed between 11 weeks and 13 weeks 6 days into your pregnancy. The test cannot be performed outside this time frame as certain features that need to be seen on the scan are not present.
Are there any possible complications? How is a CT scan done? CT stands for computerised tomography. It is sometimes called a CAT scan. CAT stands for computerised axial tomography. Sometimes the word ‘computed’ is used instead of ‘computerised’.

It is usually part of an assessment called combined first trimester screening. Combined first trimester screening Combined first trimester screening assesses the risk for your baby having certain chromosomal abnormalities trisomy 13, 18 and This testing combines the nuchal translucency ultrasound with specific blood tests. Nuchal translucency ultrasound alone can also provide this risk assessment, but it is not as accurate as combined first trimester screening.
Combined first trimester screening is a non-invasive way of assessing your risk, which means it does not involve putting needles into the placenta or amniotic sac, as happens with CVS and amniocentesis. This means that combined first trimester screening simply tells us if your risk is low or high. For example, it tells us whether your baby has a low risk of having trisomy 13, 18 or 21, or whether your baby has a high risk of having trisomy 13, 18 or This test gives us an indication of whether we should worry about your baby based on these results.
This means that combined first trimester screening will not give us a definitive answer. Chorionic villus sampling and amniocentesis are invasive tests, involving putting needles into the placenta or amniotic sac, and they are associated with an increased risk of miscarriage. For more information of prenatal diagnostic testing, please go to: The thickness of this fluid can be precisely measured and this is called the nuchal translucency or NT measurement.
Normally the amount of fluid is small, producing a thin NT measurement.
