ultrasound

The placenta is the organ that supplies all the oxygen and nutrients the
growing fetus needs.

Ultrasounds
have been used for more than 50 years to take images of the human body
for diagnostic use. During pregnancy, women are often given at least one
ultrasound to record fetal growth, number, orientation and development.

Ultrasounds, often referred to as sonograms, are digital images taken of
a fetus in-utero. Typically, a 2-D ultrasound is used to determine
fetal growth, organ development and gender.

Doppler Ultrasound gives doctors a visual or audible representation of
blood movement through veins, arteries and blood vessels with sound
waves. The reflected sound can be used to diagnose restricted blood
flow, blood clots and fetal health.

Choroid Plexus Cysts (CPC) are small fluid filled areas in the brain and they are a common ultrasound finding in the fetus during the 2nd trimester of pregnancy.

Although certain harmful effects in cells are observed in a laboratory setting, abnormalities in embryos and offsprings of animals and humans have not been unequivocally demonstrated in the large amount of studies that have so far appeared in the medical literature purporting to the use of diagnostic ultrasound in the clinical setting.

An ultrasound or sonogram during pregnancy is often used to assess the development of the fetus and to look at other structures such as the uterus, ovaries, and cervix.

A fetal echo or fetal echocardiography is an ultrasound test performed to evaluate the heart of the fetus during pregnancy and is often done as early as 20-24 weeks but can be done later in pregnancy too.

Fetal body measurements reflect whether the fetus has grown enough or whether the measurements fall outside the normal range.
The following measurements can usually be made:

An ultrasound (or sonogram) examination in pregnancy is a medical procedure that uses high-frequency sound waves to scan a person creating pictures (sonograms) of the organs being examined.

An ultrasound in pregnancy can be either done as a “routine” ultrasound, usually between 18-20 weeks or it is done for specific reasons which usually depend at the time of pregnancy.

There are several ultrasound markers for Down syndrome which can be seen on sonogram during pregnancy and which can possibly indicate an increased risk for the fetus having Down syndrome.

The growth of the fetus and the percentile of the ultrasound sonogram during pregnancy is dependent on many factors such as genetic, placental and maternal factors.

When the pregnancy hits the 20th week of gestation, an anatomic ultrasound is often ordered. The ultrasound will be used to determine fetal anomalies, the babies size, weight and to measure growth ensuring the fetus is developing according to plan.

With vaginal bleeding the risk of miscarriage is high before you see the fetal heart beat and low without bleeding after you see the heart beat

The fetal heart rate can be seen on ultrasound as early as 5 weeks 1 days of the pregnancy, and usually it's seen by 6 weeks and 0 days.

A missed abortion or miscarriage can be diagnosed on ultrasound (sonogram) with several different signs.

On ultrasound about on-half of ectopic pregnancies can be seen and the other half have only indirect signs.

The gestational age of the pregnancy, how far the pregnancy is along, can be determined accurately early in pregnancy by ultrasound measurements of the gestational sac diameter or the length of the fetal pole (CRL) in order to determine gestational age.
