Bonding with your baby with scans throughout your pregnancy There is nothing quite like watching your baby in the womb for the first time.

Lidar visualisations reveal a wide range of previously unknown Great War sites. Abstract In light of the growing interest in the Great War — stimulated by the ongoing centennial commemorations — the conflict landscape in Belgium and France is currently the subject of scientific research projects, archaeological excavations, heritage-related initiatives and exhibitions. However, the extent of the archaeological heritage and surface remains of the Great War remain underestimated.
Current heritage management and the proposal for a UNESCO nomination focus on the architectural heritage, commemorative monuments and military cemeteries, thereby overlooking the opportunities to acknowledge the conflict landscape in its totality.
A boy ultrasound is most typically described as looking like a turtle or snail, but as the beginning of this page suggests, accurate dating is very important as both genders have this shape early on. A clear boy ultrasound at 16 weeks is shown below.
You can start counting pregnancy weeks as soon as you calculate your due date based on your LMP. You will be counting your 40 weeks from the first day of LMP.

how accurate is a dating scan?
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.
Nuchal scan (NT procedure) is performed between 11 and 14 weeks of gestation, because the accuracy is best in this period. The scan is obtained with the fetus in sagittal section and a neutral position of the fetal head (neither hyperflexed nor extended, either of which can influence the nuchal translucency thickness). The fetal image is enlarged to fill 75% of the screen, and the maximum thickness is .
When will I have my first scan? Share Becky Rutherford Midwife sonographer If your pregnancy is going well, your first ultrasound scan will be your dating scan, between 10 weeks and 14 weeks of pregnancy. Early scan An early scan is offered from six weeks, so before your dating scan. Your midwife or GP will only recommend an early scan if there’s a concern, for example, if you’ve had bleeding in this pregnancy.
Your GP may also refer you for a scan if you’ve had a previous miscarriage. Many hospitals have early pregnancy assessment units EPAUs that run daily. This means you can be referred for an early scan straight away, if needed. Your sonographer may ask to carry out a vaginal scan rather than one via your tummy. A vaginal scan can offer a clearer picture of your baby earlier in pregnancy than an abdominal scan. Your sonographer will gently put a narrow device called a transducer inside your vagina.
It shouldn’t be uncomfortable. The transducer will be covered with a plastic or latex sheath and will be well lubricated with gel. Rest assured it is safe for your baby. If you feel a bit apprehensive about a vaginal scan, you may feel less worried if you:
First trimester ultrasounds
A new test can more reliably diagnose prostate cancer AND tell how big the tumour is – without the need for a rectal examination Scroll down for video A cheap, easy and accurate test for prostate cancer could be in surgeries within months. Studies show the new urine test to be twice as reliable as the existing blood test for detecting the disease — the most common cancer among British men.
It also tells doctors how serious the cancer is. This means it should not only save lives but also spare men painful, embarrassing and unnecessary tests and treatments. The new test — described as potentially the biggest breakthrough in prostate cancer diagnosis in 25 years — does not involve a rectal examination. Private patients will be the first to benefit but NHS use could follow.
\nAn ultrasound is accurate to within a couple of days if done at 8 weeks. At 20 weeks it is accurate to within a week.\n. \nAfter this babies grow at such diffeerent rates that it becomes increasingly less accurate.
Under a Creative Commons license open access Background Identification of preterm births and accurate estimates of gestational age for newborn infants is vital to guide care. Unfortunately, in developing countries, it can be challenging to obtain estimates of gestational age. Routinely collected newborn infant screening metabolic analytes vary by gestational age and may be useful to estimate gestational age. Objective We sought to develop an algorithm that could estimate gestational age at birth that is based on the analytes that are obtained from newborn infant screening.
Study Design We conducted a population-based cross-sectional study of all live births in the province of Ontario that included , infants who were born between April and March and who underwent newborn infant screening. We used multivariable linear and logistic regression analyses to build a model to predict gestational age using newborn infant screening metabolite measurements and readily available physical characteristics data birthweight and sex.
Results The final model of our metabolic gestational dating algorithm had an average deviation between observed and expected gestational age of approximately 1 week, which suggests excellent predictive ability adjusted R-square of 0. Conclusion Metabolic gestational dating is accurate for the prediction of gestational age and could have value in low resource settings.

The visual at this point is the same for a male or female child. Boy baby gender development With a male baby, between weeks 9 and 11 weeks the genital tuber becomes the glans of the penis, the urogenital folds become the shaft, the labioscrotal folds become the scrotum, and the anus is the anus still.

Either way, a sonogram — the grainy, black-and-white image that results from an ultrasound scan — will be baby’s earliest picture and a couple’s first chance to see the developing fetus.
