What if the scan shows a problem? What is an ultrasound scan? An ultrasound scan sends sound waves through your womb uterus. These waves bounce off your baby as echoes. Hard tissues, such as bone, reflect the most sound waves and so make the biggest echoes. These appear white in the image, and soft tissues appear grey. Fluids, such as the amniotic fluid surrounding your baby, appear black. This is because the sound waves go through them with no echoes.
How accurate are ultrasound scans
Testing procedure[ edit ] The examiner typically begins polygraph test sessions with a pre-test interview to gain some preliminary information which will later be used to develop diagnostic questions. Then the tester will explain how the polygraph is supposed to work, emphasizing that it can detect lies and that it is important to answer truthfully.
Then a “stim test” is often conducted: Guilty subjects are likely to become more anxious when they are reminded of the test’s validity. However, there are risks of innocent subjects being equally or more anxious than the guilty. Some of the questions asked are “irrelevant” “Is your name Fred?
First trimester ultrasound is most accurate at estimating gestational age within days (depends on the center). It trails off after that. General rule: 2nd trimester scans for dating are +/- 14 days and 3rd trimester is the least accurate (+/ days).
Share shares However, a number of unnamed sources contacted Live Science , and have confirmed that the scans did not find evidence for a secret chamber or any indication of Queen Nefertiti’s tomb. It contradicts previous work by Japanese radar expert Hirokatsu Watanabe who last year said he had evidence of two hidden chambers in the King’s tomb. Previously, researchers had said they believe there is a 90 per cent chance King Tutankhamun’s tomb contains at least one, if not two, hidden chambers.
The announcement followed infrared thermography tests shown that revealed one area of the northern wall was a different temperature to others marked Some experts believe Tutankhamun’s tomb was in fact Nefertiti’s, and when the boy king died unexpectedly at a young age, he was rushed into her tomb’s outer chamber in Luxor’s Valley of Kings ‘There is, in fact, an empty space behind the wall based on radar, which is very accurate, there is no doubt,’ he said at the time.
They feature very straight lines that are 90 degrees to the ground, positioned so as to correspond with other features within the tomb. Dr Nicholas Reeves recently claimed to have found evidence for the bricked up entrances. These include the burial chamber for Queen Nefertiti, who Dr Reeves claims was the boy-kings co-regent and may even have been his mother, and a new hidden storage room, as shown above He uncovered the ‘ghosts’ of two portals that tomb builders blocked up, one of which is believed to be a storage room.
The other, on the north side of Tutankhamun’s tomb, contains ‘the undisturbed burial of the tomb’s original owner – Nefertiti’, Dr Reeves argued. These features are difficult to capture with the naked eye, he said. Reeves said the plastered walls could conceal two unexplored doorways, one of which perhaps leads to Nefertiti’s tomb. He also argues the design of the tomb suggests it was built for a queen, rather than a king. The dark blue border shows the walls that were scanned.

Paul Berry After building the product for Huffington Post, and owning the product and engineering groups at AOL after we were acquired, it was clear to me there was a huge gap between what the current CMS offering gave the world and what the world needed.

A look at what your ultrasounds will involve. What is an ultrasound? An ultrasound involves transmitting high frequency sound waves through the uterus. These bounce off the baby and the returning echoes are translated by a computer into an image on a screen that reveals the baby’s position and movements. Hard tissues such as bone reflect the biggest echoes and are white in the image, and soft tissues appear grey and speckled. Fluids such as the amniotic fluid that the baby lies in do not reflect any echoes so appear black.
It is the contrast between these different shades of white, grey and black that allows your sonographer to capture the images. Most parents look forward to their ultrasound because it gives them the first glimpse of their baby. The sonographer or ultrasound technologist will probably give you a printout of your baby as a keepsake, although some hospitals charge for this.
However, it is important to remember that the main purpose of the ultrasound is not to provide the first photo for your baby album, or to find out your baby’s sex, either. It is to check that your baby is growing and developing normally. Who will do the ultrasound? Ultrasounds are usually performed by technicians who are specially trained in ultrasound, and are known as sonographers.

He believes there may well be a hidden chamber waiting to be discovered inside the Great Pyramid Scientists have been using a muon detecting machine pictured to scan the internal structure of the Great Pyramid of Giza.

The first trimester is months one, two, and three of your pregnancy. Below are scan pictures taken during the early weeks of pregnancy.

How would you know? The person may be able to identify basic emotions, such as intense anger, sadness or happiness yet lack an understanding of more subtle expressions of emotions such as confusion, jealousy or worry. A person is diagnosed based on the signs and symptoms he or she has rather than the results of a specific laboratory or other type of test.

What influenced me the most was my feeling that I would lose something important as a mother if I allowed someone to test my baby.

Meire, who had been performing pregnancy scans for 20 years, commented, The casual observer might be forgiven for wondering why the medical profession is now involved in the wholesale examination of pregnant patients with machines emanating vastly different powers of energy which is not proven to be harmless to obtain information which is not proven to be of any clinical value by operators who are not certified as competent to perform the operations.

William Stukeley in notes, “Pendulous rocks are now called henges in Yorkshire I doubt not, Stonehenge in Saxon signifies the hanging stones. Like Stonehenge’s trilithons , medieval gallows consisted of two uprights with a lintel joining them, rather than the inverted L-shape more familiar today. The “henge” portion has given its name to a class of monuments known as henges. Because its bank is inside its ditch, Stonehenge is not truly a henge site.
