Ultrasound scans in pregnancy

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.

Sonographer doing an echocardiogram in a child Echocardiogram in the parasternal long-axis view, showing a measurement of the heart’s left ventricle Health societies recommend the use of echocardiography for initial diagnosis when a change in the patient’s clinical status occurs and when new data from an echocardiogram would result in the physician changing the patient’s care. Transthoracic echocardiogram A standard echocardiogram is also known as a transthoracic echocardiogram, or cardiac ultrasound.

In this case, the echocardiography transducer or probe is placed on the chest wall or thorax of the subject, and images are taken through the chest wall. This is a noninvasive, highly accurate, and quick assessment of the overall health of the heart.

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.

What are Obstetric Ultrasound Scans? Obstetric Ultrasound is the use of ultrasound scans in pregnancy. Since its introduction in the late ’s ultrasonography has become a very useful diagnostic tool in Obstetrics.. Currently used equipments are known as real-time scanners, with which a continous picture of the moving fetus can be depicted on a monitor screen.

Other reasons to have a 7 week ultrasound are to: Confirm the presence of one or more embryos and gestational sacs. Assess the gestational age. When a mother has been experiencing blood loss, the ultrasound can identify the cause and source of the bleeding. Confirm the presence of a heartbeat. Check the size of the embryo and ensure the baby is the right size for gestational age. To do a general check of the uterus, fallopian tubes and ovaries.

To ensure the embryo has implanted within the uterus and there is not an ectopic pregnancy occurring. When is a dating scan necessary? This is a scan or ultrasound which determines your expected date of confinement EDC based on the development of the embryo. A dating scan is generally done for women who: Are unsure about the date of their last normal menstrual period. For women who have an irregular menstrual history or cycles.

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 “Doptone” fetal pulse detector is a commonly used handheld device to detect fetal heartbeat using the same doppler principle.

The primary aim of all our scan packages is to provide diagnostic information to our client. This well-being check forms the first part of every scan package and you will be issued with a report.

HCG Levels for normal Pregnancy. The quantitative maternal serum beta HCG peaks at approximately 10 weeks and then reduces. It will be difficult to see if the mother has a retroverted uterus or fibroids. The GS is an echogenic ring surrounding an anechoic centre. An ectopic pregnancy will appear the smae but it will not be within the endometrial cavity. Gestational sac size should be determined by measuring the mean of three diameters.

These differences rarely effect gestational age dating by more than a day or two. The following image is using a transvaginal approach the gestational sac can be seen during week Yolk Sac Only seen. The yolk sac will be visible before a clearly definable embryonic pole. 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 very early embryonic heart will be a subtle flicker.

Some studies are cited as being too small or having too many confounding factors to draw any useful conclusions. It is difficult to know what to believe Today, millions of ultrasound exams have been performed and millions of babies have been exposed during pregnancy.

Exploring the possibility that unsafe fetal ultrasounds are the source of the worldwide rise in autism. A Website for Exploring the Topic Could prenatal ultrasounds be a major contributor to the increase in autism? This website is a repository of information related to the hypothesis. Over 50 papers and articles are listed and linked on the Evidence page and are referenced throughout the website. Is prenatal ultrasound safe? The allowable intensity of prenatal ultrasound was increased 8-fold in without testing for safety then or since.

This is the entire statement: Conclusions Regarding Epidemiology for Obstetric Ultrasound http: Some studies have reported effects of exposure to diagnostic ultrasound during pregnancy, such as low birth weight, delayed speech, dyslexia, and non-right-handedness.

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.
