Development Scans

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.

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.

Fetal ultrasound measurements can show how the baby is growing and detect abnormalities. During pregnancy many different ultrasounds measurements can be done. Gestational Sac GS The gestational sac GS is a structure that surrounds an embryo and is likely the first pregnancy structure that can be seen on ultrasound in early pregnancy. The GS encloses not only the embryo, but also the amniotic fluid, which helps to nourish and protect the developing baby.

The gestational sac is the structure ultrasound technicians look for when they need to confirm the presence and viability of an early pregnancy. It can be measured across and the weeks of the pregnancy can be determined with about 5-day accuracy. Yolk Sac The yolk sac is a membraneous sac attached to the embryo. It can be seen on ultrasound between the embryo and the gestational sac.

The measurement of CRL is useful in determining the gestational age menstrual age starting from the first day of the last menstrual period and thus the expected date of delivery EDD.

Different babies do grow at different rates and thus the gestational age is an approximation. Recent evidence has indicated that CRL growth and thus the approximation of gestational age may be influenced by maternal factors such as age, smoking , and folic acid intake.
