An ultrasound scan uses high frequency sound waves which are directed through the skin and then analysed by a specialized computer to create an image of the inside of the body. X-rays are not involved and this is a painless and safe technique.

Your examination will be performed by a Berkshire Imaging Consultant Radiologist. We have dedicated ultrasound machines available at both Dunedin and Berkshire Independent Hospitals.

Ultrasound is used to examine the soft tissues of the body in real-time. Areas routinely covered include the neck, breast, abdomen (liver, gallbladder, pancreas, spleen and kidneys), pelvic organs (bladder, uterus, ovaries and scrotum), blood vessels and muscles, tendons and joints. The bowel, lungs and bones are not routinely imaged with ultrasound.

Ultrasound may also be used to guide the placement of needles for injection, for placing drains or for obtaining a tiny piece of tissue (biopsy) from a part of the body. A Doppler examination is a special ultrasound technique used to evaluate blood flow through a blood vessel.

Direct access to the skin of the area involved is required and you may be asked to change into a gown. An ultrasound probe, covered with a lubricating gel, is then moved over the skin by the Radiologist and the relevant area examined. The images can then be recorded and a detailed report produced by the Radiologist for your referring doctor.

Depending upon the area to be scanned, preparation for the test may require fasting for a few hours beforehand or perhaps attending with a full bladder. Sometimes, when examining the female pelvic organs, it is necessary to use a probe which is passed internally. Most scans can be performed within 20 minutes. Your appointment letter will give you the necessary information and also a contact number.
