The anatomy scan is a level 2 ultrasound, which is typically performed between 18 and 22 weeks. Other than finding out the sex of your baby if you want to know , the ultrasound technician will be taking many measurements of your baby.

When the pregnancy hits the 20th week of gestation, an anatomy ultrasound is often ordered. This sonogram is used to determine fetal anomalies, the baby’s size and weight, and also to measure growth to ensure that the fetus is developing properly. By the 20th week of pregnancy, the baby can weigh up to 11 ounces and measure 10 inches outstretched. The fetus has fingerprints, tiny arms and legs, and the genitalia is often formed. The rate of growth from the 20th week until the 40th week will increase exponentially.
Basically, the technician or the doctor will be looking for any signs of slower than normal development. The skeleton should be hardening at this point and the sex of the baby may be visible. In many cases, the baby may have their legs crossed or be facing away from the abdomen and thus the sexual organs will not be visible during the anatomy ultrasound. What Will Happen During the Ultrasound?
After the pregnant woman is called into the ultrasound room, she will be asked to lie flat on an ultrasound table. Her full bladder may pose a bit of discomfort, but otherwise the ultrasound will be painless and likely enjoyable. The technician or doctor will apply a warmed gel to the abdomen and use a small paddle to scan the abdomen to take a look at baby inside the uterus.
Mean Sac Diameter measurement is used to determine gestational age before a Crown Rump length can be clearly measured. The average sac diameter is determined by measuring the length,width and height then dividing by 3. The quantitative maternal serum beta HCG peaks at approximately 10 weeks and then reduces.

An anatomy scan takes much longer than any other type of pregnancy scan – it usually lasts 40 minutes but can take longer if the baby is not cooperating by lying in the correct position. You may be asked to jiggle your belly or take a short walk to get junior to cooperate. During the procedure gel is smeared to the belly area to ensure good contact between the skin and transducer the device that emits ultrasonic waves.
The transducer is placed on the belly and is rolled back and forth while internal images can be seen on a monitor next to the technician. In earlier scans the sonographer technician only takes 8 or 12 images, with this scan 40 or 50 may be taken. Images Taken During The Scan Head and Brain A cross section of the head is taken and with this measurements are taken just above the ears to get the circumference. Other brain structures will also be investigated. By looking at these scans many head problems can be ruled out including hydrocephalus water on the brain.
Spine A cross-sectional view of the spine is taken, this helps to identify spina bifida. Internal Organs The baby’s stomach, kidneys and bladder are examined for any blockages. The sonographer checks that all the organs are present and in the right position. The umbilical cord is checked, there should be 2 arteries and 1 vein going through it. The heart is evaluated – don’t worry if the technician spends a lot of time on the heart area, it is one of the most difficult areas to evaluate so it may take time to get the right images.

Their study could force a reappraisal of when certain events occurred, notably in the period when modern humans lived alongside Neanderthals in Europe. It suggests that modern humans might have lived in Europe for longer than thought and that prehistoric paintings recently found in the Chauvet cave, in southern France, might be 38, years-old rather than the estimated 33, years. An Anglo-American team found large variations in levels of the carbon isotope, used as the basis of carbon dating, preserved in a 19in stalagmite recovered from a submerged cave in the Blue Holes of the Bahamas, limestone caverns created when sea levels were nearly ft lower than today.
These findings suggested dramatic changes in the amount of radioactive carbon in Earth’s atmosphere during the last Ice Age, much greater than previously thought, probably as a result of changes in the strength of the planet’s magnetic field. The field shields Earth from cosmic rays that create carbon in the atmosphere, altering levels of the isotope during the past 45, years. Radiocarbon dating, which depends on the steady decay of carbon , is less reliable if an artefact is older than 16, years.
