Using advanced imaging ultrasound systems, Synergy Radiology provides high image quality for medical diagnosis in obstetrics. Our sonographers and specialist radiologists highly trained and experienced in all facets of obstetric imaging. It is important to bring all previous results relating to the region being imaged. Please be on time for your appointment to ensure there is sufficient time available to perform the procedure. To ensure clear images, you will be asked to attend with a full bladder. This is achieved by emptying your bladder 2 hours before your appointment and then immediately drinking ml of water. Do not empty your bladder again before the procedure. You may eat normally and take any necessary medication. The ultrasound waves are transmitted and collected via a hand held probe which is moved over the abdomen.

We did the ultrasound, we saw the uterus and yolk sac but no fetal pole. Could my dates be off even though I know when my last period was?
You may be concerned when you go in for a pregnancy ultrasound only to hear that a gestational sac could not be seen. Learn when it is usually seen and the different reasons why it can’t be found on an ultrasound in early pregnancy. The transvaginal ultrasound is generally used because an abdominal ultrasound is much less accurate this early in pregnancy.
The gestational sac is usually seen on ultrasound by 5 weeks gestational age but is sometimes seen as early as 3 weeks gestational age. When identified on the ultrasound, the diameter of the sac is around 2 to 3 millimeters and is seen as a white rim around a clear center in your uterus. If you are also having quantitative pregnancy tests serum hCG tests the gestational sac usually becomes visible when hCG levels have reached to The next step on ultrasound is usually the appearance of the yolk sac within the gestational sac.
The yolk sac functions as nourishment for the developing embryo and can usually be seen by 5.
What Does No Gestational Sac on My Ultrasound Mean?
A dating scan is an ultrasound examination which is performed in order to establish the gestational age of the pregnancy. Most dating scans are done with a trans-abdominal transducer and a fullish bladder. If the pregnancy is very early the gestation sac and fetus will not be big enough to see, so the transvaginal approach will give better pictures.
The scan may also show if you are expecting a baby girl or boy. Please note if your baby’s lying in easy to tell the gender of the baby. The hospital will not offer you another scan if this is the case. Date pregnancy by measuring your baby.
First trimester scanning is useful to identify abnormalities in the early development of a pregnancy, including miscarriage and ectopic pregnancy, and provides the most accurate dating of a pregnancy. Technique First trimester scanning can be performed using either an abdominal approach or a vaginal approach. Abdominal scanning is performed with a full maternal bladder, provides a wider field of view, and provides the greatest depth of view.
Vaginal scanning is best performed with the bladder empty, gives a much greater resolution with greater crispness of fine detail. In circumstances where both approaches are readily available, the greater detail provided by transvaginal scans usually outweighs other considerations, and is preferred. The patient is scanned in the normal examination position dorsal lithotomy with her feet secure in stirrups and her perineum even with the end of the examination table.
Place a small amount of ultrasonic coupling gel on the tip of the transvaginal transducer. Then cover the transducer with a condom. After lubricating the vaginal opening, gently insert the transducer into the vagina. Visualize the longitudinal plane of the uterus sagital section and evaluate its’ size.
Scans in the first trimester
the early scan helps us to work out the date when your baby is due. This is because not all pregnancies are conceived exactly 14 days after the first day of the it involves an ultrasound scan (the ‘nuchal translucency scan’) and a blood test.
At around seven weeks of your pregnancy, the embryo begins to grow hands and feet. This is when the mother can see her baby for the first time through an ultrasound. This scan is performed for various purposes. Getting an ultrasound done has the following benefits on the baby —. Women who have an irregular menstrual cycle or do not remember their last menstrual period date find it challenging to calculate their due dates. In such situations, a dating scan to estimate the approximate gestational age of the baby can be helpful in calculating the estimated delivery date.
It is also useful in monitoring the growth of the baby. The ultrasound at seven weeks can be done in two different ways. Depending on the health of the expecting woman, a transvaginal scan or abdominal ultrasound is performed. A transvaginal scan involves inserting the probe vaginally and for that, the woman needs to have a full bladder before the scan. However, if it is an abdominal ultrasound, a full bladder is necessary for a clear vision of the foetus.
The seventh-week ultrasound does not take more than a few minutes.

A beautiful, supremely talented young friend of our family recently fell victim to a terrible medical mistake. Newly married, she was having some pelvic pain and bleeding, and the doctor who saw her diagnosed a probable ectopic pregnancy — an embryo that develops outside the womb. Concerned that such pregnancies can turn life-threatening, the doctor prescribed the standard treatment: methotrexate, a drug used for chemotherapy and to help induce abortions.
When our friend returned to be checked a few days later, the imaging revealed that in fact, the pregnancy had not been ectopic; it was in place, in her uterus. But because she had taken the methotrexate, a known cause of birth defects, her pregnancy was doomed. She soon miscarried. What may have been a perfectly healthy pregnancy had been ended by well-meant medical treatment.
I assumed her horrifying case was an exceedingly rare medical fluke — until now. A paper just out in the prestigious New England Journal of Medicine shows that such misdiagnosed pregnancies are part of a pattern — a pattern that needs to be changed. When I told our friend’s story to the paper’s lead author, Dr. Peter Doubilet, he responded that he knows of “dozens and dozens and dozens of similar cases that have come to lawsuits, and that’s probably the tip of the iceberg.
The New England Journal of Medicine paper stems from a panel of international experts who resolved to change medical practice to stop such misdiagnoses.

What to expect at your 6-week ultrasound appointment
Whilst you may get a positive pregnancy test before your period is even due it is a couple of weeks before the pregnancy is big enough to be seen on scan. In the early weeks how much we can see in very early pregnancy is different for every woman and every pregnancy. At 4 weeks gestation 2 weeks after conception when you have just missed your period we cannot detect the pregnancy on scan, all we can see is that the lining of the womb has become thicker.
Somewhere between 4 and 5 weeks, we can sometimes see a small black fluid area in the uterus but we cannot confirm it is a pregnancy sac until we can see something growing inside it. During the 5th week we can usually see a small pregnancy sac around 6mm and within it we can usually see a yolk sac. This confirms to us that this is definitely a pregnancy sac.
