Ultrasound is a safe and widely used test that produces detailed images of the body in real-time. It is done by a specially trained health professional called a sonographer.
During the ultrasound exam, a handheld device called a transducer is placed on your skin over the area of interest. The transducer sends high-frequency sound waves into the body. Sound waves reflected by the different types of tissues and organs in your body are converted into an image by the ultrasound machine. Ultrasound does not emit ionising radiation and is considered safe in pregnant women and children.
Ultrasound has many uses. In addition to being used during pregnancy, it also provides high-quality images of the organs in the abdomen and pelvis, musculoskeletal system, breast, and blood vessels of the body.
Preparation for your exam depends on the body part being imaged. Please refer to the specific examination page for details as following the instructions for your ultrasound is essential.
Ultrasound exams usually take 30 minutes. Some examinations may take longer, for example, certain obstetric (pregnancy) scans or vascular (blood vessel) studies.
A radiologist (specialist medical doctor) will review the images and provide a written report to your doctor. On occasion, the radiologist may personally attend your examination to discuss your issue and view images while the procedure is being undertaken.

Ultrasound is a safe procedure used extensively in children as there is no radiation and no known risks. Children have ultrasound procedures done in the same way that adults do. Some scans may require a paediatric radiologist. We will inform you if this is necessary at the time of booking.
