Visit our community What is an anomaly scan? An anomaly scan, also known as a mid-pregnancy scan, takes a close look at your baby and your womb uterus. The person carrying out the scan sonographer will check that your baby is developing normally, and look at where the placenta is lying. This image shows a baby’s face and hands at 20 weeks, and gives you an idea of what you will be able to see at this scan. Seeing your baby on a screen can be really exciting. You can also take your partner , friend or family member along to share the experience with you.

Sometimes, the sonographer can’t get a good enough view to tell the gender, perhaps because of your baby’s position, or if you have a lot of tummy fat NHS a. And some hospitals have a policy of not telling parents-to-be, to prevent mistakes in identifying gender from happening.

12 week pregnancy dating scan: here’s what to expect
Email Advertisement Do online dating websites work? To explore this topic, I pulled aside two individuals who I knew were hunting for a long-term relationship using online dating websites, and asked them about their experiences with the services. The two services used by these individuals were OKCupid and Match. What I learned from carrying out an interview of a female and the interview of a male trying to dig into this intriguing subject was that using the Internet for dating is equally painful for men and for women, but for very different reasons.

Hutchon’s site and the Gestation Network also provide pregnancy calculators. A large number of mails I received are about fetal anomalies, I have therefore tried to put together a Catalogue of Web pages which describe in some detail specific congenital anomalies that are diagnosable by ultrasound. You can visit the page here. I am pregnant for 7 weeks. I went for a scan yesterday and was told I should have a full bladder. They made me drink 4 cups of water and my bladder was almost bursting at the end of the session.
Is this really necessary? A full bladder is usually necessary when the scan is done abdominally and in the early part of pregnancy. This would tend to lift the uterus up a little bit and being in front displaces the bowels away and act as an echo-lucent windows for the ultrasound to pass through. Ultrasound doesn’t go through air as in the bowels well but transmits perfectly through liquid as in the case of the urine in the bladder.
Your doctor will be able to see things so much more clearly with the full bladder there especially the presence or absence of fetal heart beat. In a vaginal scan however, a full bladder will not be necessary.
Posted on January 17, by Marti Benedetti In November, just after my birthday, and after eight months of dealing with progressively crippling bone pain, I was handed the medical diagnosis of breast cancer that had metastasized into my bones. This is a mother fucker because for months I had mysterious sore and broken ribs, severe back pain, upper leg discomfort, a gradual loss of overall mobility, and I witnessed first hand going from an in-shape, active woman to handicapped.
And to worsen the whole mess, not a single doctor diagnosed my illness over nine months nor did one show interest in the fact that I was becoming seriously ill. The doctors only took blood work, never a CAT scan, MRI or bone scan, any of which would have revealed I had aggressive, bold, gnaw-through-your-bones cancer. So five weeks after being taken to the emergency room because I was paralyzed from the waist down one morning, emergency spine surgery was conducted to remove a cancerous martini pickle-sized tumor.
I spent 10 days in the hospital and went home so my back could heal.

History Galton whistle, one of the first devices to produce ultrasound Acoustics , the science of sound , starts as far back as Pythagoras in the 6th century BC, who wrote on the mathematical properties of stringed instruments. Echolocation in bats was discovered by Lazzaro Spallanzani in , when he demonstrated that bats hunted and navigated by inaudible sound, not vision. Francis Galton in invented the Galton whistle , an adjustable whistle that produced ultrasound, which he used to measure the hearing range of humans and other animals, demonstrating that many animals could hear sounds above the hearing range of humans.
The first technological application of ultrasound was an attempt to detect submarines by Paul Langevin in The piezoelectric effect , discovered by Jacques and Pierre Curie in , was useful in transducers to generate and detect ultrasonic waves in air and water. In air at atmospheric pressure, ultrasonic waves have wavelengths of 1. The Mosquito is an electronic device that uses a high pitched frequency to deter loitering by young people. Animals Bats use ultrasounds to navigate in the darkness.
A dog whistle , a whistle which emits sound in the ultrasonic range, used to train dogs and other animals Bats use a variety of ultrasonic ranging echolocation techniques to detect their prey. These include many groups of moths , beetles , praying mantids and lacewings. Upon hearing a bat, some insects will make evasive manoeuvres to escape being caught.
Doppler Ultrasound The doppler shift principle has been used for a long time in fetal heart rate detectors. Further developments in doppler ultrasound technology in recent years have enabled a great expansion in its application in Obstetrics, particularly in the area of assessing and monitoring the well-being of the fetus, its progression in the face of intrauterine growth restriction, and the diagnosis of cardiac malformations. Doppler ultrasound is presently most widely employed in the detection of fetal cardiac pulsations and pulsations in the various fetal blood vessels.

Ultrasonic Fetal Measurement Standards If we assume a fetus is growing normally, biometric measurements are determined by gestational age, and we can estimate the gestational age and thus the due date. Conditions which alter fetal growth will make the estimates less reliable. Although many embryonic and fetal structures can be measured, only a few measurements are easy and repeatable enough for widespread use. The most common are: The first element to be measurable is the gestation sac of the early pregnancy.
The gestational sac is measured in three dimensions, and the average, the Mean Sac Diameter MSD used for estimating gestational age. The length of the embryo on the longest axis excluding the yolk sac constitutes the crown-rump length. The transverse width of the head at it’s widest. We measure from the the leading edge to leading edge of the bones, because this leading interface is most distinct. Since the head is oval, the error induced by small errors in positioning is small, making for a repeatable, robust measure.
The BPD best used after 12 weeks. The femur length is a repeatable measurement with accuracy similar to the BPD. It is effected by skeletal dysplasias, but since these are rare, it is a reliable measurement which confirms measurements of the head.

Hey all, So I got my appointment letter through from the hospital for my dating scan and it will be at about 10 weeks. I know that the NHS say these are between 8 and 14 weeks but I thought they couldn’t do the usual tests until about 12 weeks.
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.

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. Pioneers It is often overlooked that throughout the nineteenth century, most of the electrical experimenters, inventors and engineers who made these advances possible had to make their own batteries before they could start their investigations.
They did not have the benefit of cheap, off the shelf, mass produced batteries. For many years the telegraph, and later the telephone, industries were the only consumers of batteries in modest volumes and it wasn’t until the twentieth century that new applications created the demand that made the battery a commodity item. In recent years batteries have changed out of all recognition. No longer are they simple electrochemical cells.
