Ultrasound – also know as a sonogram – is widely used to capture real time images, allowing assessment of organs, vessels and other tissues, all without making an incision.
The technique uses high-frequency sound waves to capture the images and unlike other imaging techniques, ultrasound uses no x-rays. It is the gold standard to view a developing baby during pregnancy.
Ultrasound uses high frequency sound waves to produce images. There is no radiation in an ultrasound. They are used for many examination purposes, including during pregnancy, musculoskeletal, vascular, renal and for interventional purposes to guide biopsies and injections.
What is the preparation for the test?
Preparation will vary depending on the area being examined. Full preparation detail will be provided at the time of booking, but may include requiring a full bladder.
How is the test performed?
You may be asked to change into a gown. The ultrasound transducer will be in direct contact with the skin, a lubricating gel will be used to enable the sonographer to guide the transducer more effectively and allow for better reporting images.
Will I feel anything?
You may feel the gel on your skin and sometimes it is necessary for the sonographer to apply pressure to a certain point to identify certain areas. You should not feel any pain.
How long will it take?
A scan will usually last around 20 minutes but may take longer depending on the actual area(s) being imaged.
