Accuracy of Transvaginal Ultrasound for Dating Pregnancy

The embryo’s head lies at one end and something similar in appearance to a tail lies at the other end. When Does Fetal Pole Develop? At around the fifth week of pregnancy, ultrasound scans can identify the gestational sac. For this, a trans-vaginal ultrasound scan is considered superior to a trans-abdominal ultrasound scan as it can detect these development changes much sooner. By the middle of the fifth week, a yolk sac can be seen within the gestational sac. It will act as a source of nutrients for the developing fetus. The levels of human chorionic gonadotropin hCG hormone increases during this period as do progesterone levels.

Share this article Share They register differences between normal breast tissue and a collection of blood and water contained in a tumour. In pilot studies on women, the system picked up about 80 per cent of tumours — a success rate close to existing techniques. Two scans of the same woman with a small tumor in her breast: The scan on the left is a traditional x-ray scan where the tumor is not visible, the scan on the right is using new technology where the tumor appears in blue Dr Mike Shere, breast specialist at Southmead Hospital, said: It is quick, safe, comfortable and cheap, and is already producing good images with high sensitivity.

This technology uses radio waves which are almost exactly the same as mobile phone frequency — and less energy. It is completely safe, unlike mammography, where there is an increasing cancer risk when women have more X-rays. In four out of five cases, the tumour was identified and clinicians expect the rate to increase to 90 per cent.

The new system has none of the drawbacks of mammogram scans, where there is an increasing cancer risk due to the use of X-rays Dr Shere said: Share or comment on this article.

References “The technology of prenatal diagnosis is usually presented to us as a solution, but it brings with it problems of its own If you’ve already read it, you may want to skip ahead. All pregnant women in our technology-happy modern society face confusing choices about prenatal testing, its advantages and disadvantages, and its appropriateness for them. Large pregnant women face even more confusion, since prenatal testing can be slightly harder in this population, and the results can be more confusing.

However, since they may be at a somewhat increased risk for problems like neural tube defects, they also face greater pressure than others to have these prenatal tests, even though the tests are often difficult to interpret. It is further designed to address the special concerns that large women might have in taking these tests their fears, any special equipment or techniques that might be helpful, the controversies over interpretation of results, whether large women have a higher rate of so-called ‘false-positives’ on certain tests and why, etc.

Well, one of the major things that I think we were wanting to get out of the scan was to discover that there was only one baby, because my husband is a twin and as far as I was aware, there was no history of twins in my family. But it actually turns out that my father’s parents on both sides there had been a history of identical twins, but they had died so we didn’t know about it, because they’d died as babies. I actually was kind of thinking, ‘Oh, well, if it was twins then what you don’t know won’t hurt you’.

And, you know, I’ve never had a baby before so if I had two then I wouldn’t know any different to just having one. My husband, on the other hand, was quite relieved to see there was only one, because he was of the opinion that one would have to be sold because we wouldn’t be able to afford two! So he was quite pleased. Did you know about your family history then, before you went for the scan or did it only come up afterwards when somebody said, ‘Oh, yeah, we’ve got twins too’? It came up when I found out I was pregnant.

Because my husband’s a non-identical twin, so we didn’t think there was much risk of any sort of genetic thing, but the fact that there was identical twins was kind of a bit of a, ‘Oh, right, okay, you might have told me that beforehand.

I originally had a dating scan at 9 weeks which found a luteal cyst on my left ovary which was 8cm. I was referred to the antenatal clinic and began seeing a consultant after each subsequent scan. At my 12 week scan they found the cyst had grown to 12cm. I was reassured at all my appointments that they are common in pregnancy though not usually that large and they would be reluctant to do anything at this point due to the risks involved and these cysts usually resolve and disappear by your 2nd trimester scan.

At my 21 week scan it had grown further to It was incredibly scary but the entire team from midwives to the doctors I saw were fantastic at answering questions and supporting me especially when I had a panic attack in clinic after being told they would operate! They made an incision much like a Caesarian and removed the cyst which had grown to 14cm. I have to be honest and say it was the scariest and most painful experience of my life so far, and those first few days post op were horrible but my baby was fine, and they checked her heartbeat with the Doppler times a day to monitor her and reassure me.

It was a hard experience but ultimately the best decision for me and my baby’s health, and I have been reassured i should be able to go on to have a normal delivery. I am measuring small but have a growth scan in a few days to check baby and ensure she’s healthy and hopefully wipe away any lingering doubt to negative effects of the op on her.
