If you have problems understanding and calculating your due date, check out and download a copy of the Ob calculator by York Winston. 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.
When will I have my first scan?
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.
The scan is usually done transabdominally, but occasionally it may be necessary to do the scan transvaginally: The purpose of the week scan: To date the pregnancy accurately. This is particularly relevant for women who cannot recall the date of their last period, have an irregular menstrual cycle, or who have conceived whilst breastfeeding or soon after stopping the pill.
We measure the size of the fetus and from this we calculate the expected date of delivery. To diagnose multiple pregnancy. Ultrasound scanning can determine if both babies are developing normally and if the babies share the same placenta which can lead to problems in the pregnancy.
Nuchal translucency (NT) scan
Contact Us About us At the Fetal Ultrasound Centre we provide our patients with a professional, informative and memorable ultrasound examination. In addition to the First Trimester Downs Syndrome risk assessment and Fetal Anomaly scans, we also provide services such as early pregnancy dating, gender determination, growths scans and 4D ultrasound scans. She obtained her B-Tech degree in Ultrasound after completing two years of full time training at the world renowned Obstetric Ultrasound Unit in Tygerberg Hospital.
Here, and in the surrounding clinics in Cape Town, is where she gained her invaluable experience and knowledge in Obstetric ultrasound scanning.
The first trimester is months one, two, and three of your pregnancy. Below are scan pictures taken during the early weeks of pregnancy. Measurements taken at these early scans will help to; confirm a pregnancy, date the pregnancy and to see any problems that may occur in the pregnancy (low lying placenta, twins etc.).
Ultrasound Scans Dublin Some Common Questions If you are wondering why you should have an early pregnancy scan , why not take a look at this video where one of our consultants, Dr. Shane Higgins, explains clearly the reasons for attending an early pregnancy scan — just click on: Especially if this is your first pregnancy, you may also be unsure as to when is the earliest you could have your first scan.
Normally this 1st trimester scan is undertaken from 6 to 12 weeks. These weeks refer to the gestational age of your baby, and what this means is that the date is taken from your last period. However we often recommend leaving this scan until after 7 weeks if possible, because at this stage we can normally get more accurate information at your scan. Also this first pregnancy scan is when we should be able to see how many babies are in your uterus, for those of you who are pregnant with multiples.
Of course you will want to know your estimated due date, and we can also give you this information at the early pregnancy scan. Sometimes baby could be located in the fallopian tubes and this can be determined at this time. This is called an ectopic pregnancy.
Nuchal Translucency Ultrasound
First trimester ultrasound is performed in the first months of a pregnancy. Pregnancy ultrasounds are performed mainly using transabdominal ultrasound. For many women, especially after 8 weeks gestation, sufficient information about the baby may be obtained with transabdominal ultrasound only. However, in the early pregnancy, the developing embryo is very small at 6 weeks gestation, the baby is only mm long and a transvaginal ultrasound may be required to get a better image of the baby.
Transvaginal ultrasound is safe and commonly performed during all stages of pregnancy, including the first trimester. It will not harm you or your baby.
Question: 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 .
Well, if the measurements indeed indicate a gestational age of 9 weeks, then it would be most unlikely not to be able to see the heart beat at this time. Very likely fetal demise has occurred. Don’t expect the fetus will carry on growing without a pumping heart. Can you tell me what the nuchal skin fold is for and what would be the use of measuring it during an ultrasound examination?
The nuchal skin fold thickness or nuchal translucency is the thickness of the skin fold behind the nape of the neck. In chromosomal abnormalities this may be thickened due to venous or lymphatic engorgement. It is now almost routinely measured between 11 to 14 weeks to detect the presence of Down syndrome and fetuses with other chromosomal abnormalities. I am 18 weeks at dates. I had an ultrasound scan last week and the technician told me that the baby’s intestines looked whitier than they should be.
She said she could not find any other peculiarity about my baby but suggested that I should come back for an amniocentesis this week. What does that mean? Does my baby have Down syndrome? I believe she is referring to ‘echogenicities’ in the fetal bowel which is considered to be one of the ultrasonic “soft signs” suggesting that the fetus may be suffering from chromosomal abnomalities the most common one of course is Down syndrome.

Can the scan show the gender of my baby? What is actually done? Scans are usually performed by a doctors, midwives or radiographers who are specially trained in ultrasound, and are known as sonographers. The whole pregnancy will be assessed. The amount of liquor amniotic fluid , the position and appearance of the placenta and a detailed scan of the baby itself. The baby will be measured, and the anatomy examined in detail.
Nuchal Translucency Test-What To Expect
Will I be given a risk level for any other abnormalities? What is nuchal translucency? Nuchal translucency is a collection of fluid under the skin at the back of your baby’s neck. The amount of fluid is measured during a nuchal translucency NT ultrasound scan: That’s why the NT scan is used to help screen for Down’s syndrome.
A NATURAL BIRTH ADVOCATE. He is an active supporter of natural birthing options and is willing to attend a home birth. He is supportive of women choosing to have a birth plan and utilizing methods such as HypnoBirthing and Spinning Babies.
International conference on transition and cord clamping at birth April It is increasingly recognised that the circulatory changes involved in transition at birth cannot occur within a few seconds of birth. While the healthy fetal circulation and the healthy neonatal circulation are moderately well understood, the underlying triggers, the precise sequence and speed of the changes in the circulation are not.
How can we interefere in something we do not understand? Nearly all textbooks and journals which include the physiological transition of the neonate at birth describe a marked change in the peripheral vascular resistance and an increase in the afterload of the heart. One notable exception is Gray’s Anatomy.
Gray’s Anatomy describes inflation of the neonatal lungs as the first change after birth and does not describe any changes in the afterload of the heart. Afterload is the force that the myocardium generates during ejection against systemic and pulmonary vascular resistances. Reductions in afterload increase stroke volume if other variables remain constant. Gray’s Anatomy also describe the release of bradykinins from the pulmonary vascular epithelium which are vasoconstrictors to the umbilcal arteries.
