Scans in early pregnancy are being used to confirm a pregnancy and a baby's heartbeat. You may had vagina bleeding or you are concerned because you had problems with previous pregnancy. The early pregnancy ultrasound scan also known as baby viability scan can provide the very much needed reassurance that the pregnancy is progressing normally and it is not an ectopic.
This pregnancy scan can detect the embryonic heart beat as early as 6 weeks gestation.
Reasons for having this baby reassurance scan include:
Purpose of this baby scan is:
The scan incudes: Ultrasound report with a 2D b/w picture
We need your bladder full for this scan so you need to drink 1lt (2 pints) of water an hour before your scan.
Before the early ultrasound scan, our sonographer will explain the examination procedure.
This early baby scan is normally performed trans-abdominally. In some instances, however an internal scan (Transvaginal) may be required to see all the necessary detail or if your womb tilts backward.
We will always try to scan trans-abdominally first but if we need to do an trans-vaginal ultrasound scan then we will discuss this with you. To perform this early baby scan, you will be asked to lie down on the examination couch and expose your lower abdomen.
A small amount of water-based gel will be applied to your skin. The gel will help the transducer to make good contact with the skin. The ultrasound transducer will be placed on the body and will be moved in different directions over the area of interest to obtain the required information/ultrasound images.
There is usually no discomfort from pressure as the transducer or probe as otherwise known, is pressed against the area being examined. However, if scanning is performed over an area of tenderness, you may feel pressure or minor discomfort from the transducer.
Once the ultrasound imaging is completed, the clear ultrasound gel will be wiped off your skin. Any portions that are not wiped off will dry quickly. The ultrasound gel does not usually stain or discolor clothing.
This ultrasound examination is usually completed within 20-30 minutes. After an ultrasound examination, you should be able to resume your normal activities immediately.
These are some of the most frequent questions our clients ask about early pregnancy ultrasound scans:
The early pregnancy baby scan is used to see how far along in your pregnancy you are and check your baby's development. ThisÂ ultrasound scan can routinely detect a baby's heartbeat asÂ earlyÂ as 6-7 weeks and confirm the correct dates of your pregnancy.
6 weeks â€“ At this stage the pregnancy is of course small, but we should be able to see the gestation sac with a yolk sac developing in your uterus. We should be able to see your baby's heartbeat on scan, which is very reassuring.
At 5 weeks pregnant you will be able to see a small gestation sac in the uterus.
At 6 weeks pregnant within the uterus you will be able to see a small gestation sac and maybe a small yolk sac.
Between 6-7 weeks a fetal pole might be seen. Foetal pole is the start of seeing a baby but still measuring only a few millimetre with a heartbeat and the chances of pregnancy continuing are high, close to 80%.
At 7 weeks gestation, the baby usually measures 10 â€“ 20 mm and the heartbeat can be seen.
At 8 weeks pregnant, the baby measures between 20 and 30 mm and the heartbeat is clearly visible. The chances of the pregnancy continuing in that stage is 98%
At 10 weeks pregnant the baby is now between 35 and 40mm and if the baby heartbeat can be seen the chances of the pregnancy continuing is 99.4%. At 11+ weeks pregnant the baby is now measuring around 45mm and the head, body, arms and legs can be seen. The heart, the stomach, bladder and cord insertion can be seen.
The fetal pole is the first direct imaging manifestation of the fetus and is seen as a thickening on the margin of the yolk sac during early pregnancy. It is often used synonymously with the term "embryo".
Progesterone levels also can have quite a variance at this stage of pregnancy. They can range from 9-47ng/ml in the first trimester, with an average of 12-20ng/ml in the first 5-6 weeks of pregnancy. With both hCG levels and progesterone levels, it is not the single value that can predict a healthy pregnancy outcome.
Fetal pole or yolk sack can be seen from 7 weeks. In these cases where the yolf sack is not seen a follow up scan will be recommended 7-10 days later.
Our ultrasound scanner is brand new and utilises the latest break through ultrasound technologies to increase diagnostic accurancy and diagnostic confidence. Utilising up to date technology helps to keep ultrasound expose to the foetus as low as reasonably possible.
