Ultrasound scans are undertaken at both of our hospitals. Please remember to check your appointment letter to see which hospital you are due at before you come for your scan.
Women's ultrasound - for obstetric and gynaecology
Opening hours: Monday-Friday, 8am-6pm. By appointment only.
What is an ultrasound scan?
An ultrasound scan uses high frequency sound waves to produce pictures of the inside of your body. It helps us find the cause of your problem, and the best treatment options for you.
We also use an ultrasound scan to follow the progress of a pregnancy.
Giving your consent
The sonographer or radiologist will ask you if you are happy for the scan to go ahead. This is called verbal consent and may only involve the sonographer checking you are booked for the correct scan. If you do not wish to have the scan or are undecided, please tell the sonographer.
It is your decision and you can change your mind at any time. Please bear in mind that not having the scan may delay your diagnosis as the doctors may not have all of the information that they need. Please remember that you can ask the sonographer any questions you have at any time before, during or after your scan.
Please have a look at our consent policy for more information.
What happens during an ultrasound?
The sonographer or radiologist will ask you to lie on a couch. He or she will apply some gel to the area of your body that is going to be examined, so that the sound waves can be transmitted through the body.
He or she will then move a small scanning instrument (called a transducer), over this area. The sonographer or radiologist will be able to see the scan images on the screen.
You should not feel any pain during the scan. If you find it difficult or uncomfortable, please tell the sonographer.
An ultrasound scan usually takes 10-20 minutes, depending on the area of your body that is being scanned.
What happens after the scan?
In most cases, you will be allowed to go straight home or back to the ward if you are an inpatient. You can eat, drink and go back to your normal activities straight away.
The results will be sent to the doctor who referred you. If that doctor is a consultant at Guy's and St Thomas', the results will normally arrive within one working day. If it was your GP or a consultant at another hospital, it is normally within one week.
If you are an inpatient, the results will be given to the doctors looking after you on the ward.
Antenatal reports will be placed in the patient’s maternity notes at the end of the ultrasound scan.
