What to expect during an ultrasound scan

Ultrasound scans produce images of muscles, tendons and internal organs in real time. Capturing size, structure and any pathology.

  • Ultrasound scans are a safe procedure, utilising sound waves, no radiation is involved.

  • The scope and process of the scan will be discussed with you before commencing. Please let us and your healthcare provider know of any concerns you have.

The preparation required for a scan depends on the type of ultrasound requested. However, regardless of procedure it is always advisable to wear loose, comfortable clothing.

  • Below are some of the most common examinations, and the preparation requirements. It is advisable to double check with your healthcare provider to confirm.

 General Preparation Requirements

* Remember to consult with your healthcare provider if you have any questions or concerns about the preparation process. Following these guidelines will help ensure that the ultrasound provides accurate, useful information and images.

  • Please wear loose, comfortable clothing.

    In most cases, you will need to fast (avoid eating, drinking) for 6 hours prior to the examination. This will ensure that your stomach and intestines are empty, providing a clearer view of the organs.

  • The preparation necessary depends if an internal or external pelvic ultrasound is required. A transvaginal ultrasound provides much more detailed pictures of the organs in the pelvis, particularly the uterus (including fallopian tubes and ovaries), when compared to ultrasound scanning of the pelvis from the lower abdomen.

    Internal Pelvic Ultrasound

    • Also called Transvaginal Ultrasound. Generally only recommended for patients aged 18 and over.

    • You will be asked to empty your bladder before the examination, no further preparation will be required.

    External Pelvic Ultrasound

    • Performed when Transvaginal Ultrasound is not appropriate for the patient. To ensure that we can get the best possible image of the lower abdomen in this scenario, a full bladder is required. This means 3 glasses of water will need to be consumed at least 30 minutes before the procedure, without going to the bathroom.

  • For some pregnancy ultrasounds, particularly in the early stages, you will be asked to have a full bladder for the examination. In this case, having a full bladder can help create a better acoustic window and improve the visibility of the uterus and developing fetus.

  • If the patient is a baby, infant or child (up to 18 years), special instructions will apply. Please contact us or your healthcare provider so that you receive the instructions and advice appropriate to your child’s age. This will ensure the best test is performed at minimum discomfort to your child.

  • Drink 1 litre of water (4 glasses) of water 30 minutes before the appointment, do not empty the bladder until after the appointment.

  • Please wear loose, comfortable clothing. No additional preparation is required.
