What is Ultrasound?
Ultrasound is very high frequency sound waves (1-17 Mhz in diagnostic ultrasound). The sound waves are transmitted into the body by the camera called a transducer. The waves reflect off the different tissues with the returning echoes detected by the transducer. The machine transforms these echoes into amazing pictures which can be viewed as a real time image. The technology is stunning.
Is it Safe?
Yes. Diagnostic ultrasound scans are safe for you and your baby.
Ultrasound is the only type of imaging that is used routinely to monitor pregnancies.
What is a transvaginal scan (internal scan)?
A transvaginal scan is performed with a thin transducer (ultrasound “camera”) placed in the vagina. This scan normally gives the best images of the uterus, ovaries and other pelvic structures and is excellent for looking at very early pregnancy. The scan is normally simple and painless. The bladder is emptied and the patient covered with a sheet. A sterilised transducer with a protective cover and gel is used. The patient guides the transducer into position and the scan performed.
It is the patient’s choice to consent to an internal scan.
Can I still have a transvaginal scan if I have my period?
Yes. Transvaginal scans can be performed at any time during the menstrual cycle, including while you are having your period, but in some cases, another ultrasound may need to be performed after the next period. The preferred time for a pelvic scan is just after the period has finished, if possible.
Why do I need a full bladder?
A full bladder helps to push bowel gas (which blocks the ultrasound) out of the way and acts like a window allowing good views.Please visit our Patient Preparation section for more information.
For a female pelvic scan, most people do not need a full bladder for good scans, however sometimes we may ask you to drink more water to fill the bladder, if bowel gas is in the way.
If a transvaginal (internal scan) is to be performed, a full bladder is not required.
When is the best time to find out the sex of a baby?
The 18-20 week anatomy scan (also known as the morphology scan) is a good time to determine the sex of the baby. Sometimes if the baby is not in a good position we may not be able to get a good view. It is possible to determine the sex earlier in pregnancy, such as the nuchal scan, but this is a less reliable time.

Do you do 4D scans?
Please note that during Alert Level 4 for the Covid-19 Virus, we are not performing 4D ultrasounds.
Yes. 4D scans are best when the baby is over 26 weeks and up to 30 weeks. The fee includes all electronic images on an Advance Ultrasound USB memory stick and a print of the best image. A signed referral form from your midwife or referrer is required if you have been referred for a growth scan and are between 26 to 30 weeks. A 4D scan can be performed after your growth scan as a separate procedure, this requires additional time and must be booked in advance, you do not need a referral form for a 4D scan without a growth scan.
