ULTRASOUND

What is an ultrasound? 

Ultrasound examinations can be performed on most parts of the body and they provide excellent information about a variety of conditions – from pregnancy to gall stones, varicose veins and even muscle tears.

Scanning may take up to 1 hour but generally most appointments are for 20–30 minutes. Ultrasound examinations are carried out and interpreted by a radiologist (a doctor trained in reading X-rays and ultrasounds) and a sonographer (a technologist trained in ultrasound imaging).

Often your radiologist will speak with you while viewing the ultrasound screen – this is quite routine and should not cause alarm. The images are then interpreted by the radiologist and the results are forwarded directly to your doctor.

Ultrasounds do not use radiation. Instead, they use high-frequency sound waves (much higher than human ears can hear), which are produced by the ultrasound probe (transducer). The reflected sound waves are detected by the probe and used to create an image, which is displayed on the monitor of the ultrasound machine.

Sometimes ultrasounds are used in interventional procedures. They are most commonly used to guide a needle into an area for administering cortisone – to reduce inflammation or drain fluid from a joint – or even during a biopsy.

Before the appointment

Depending on the ultrasound examination your doctor has requested, you may need to fast from food and fluids. Some examinations require you to drink a significant amount of water prior to arriving so that your bladder is full. You will be advised of any necessary preparation when you make a booking.

At the time of your ultrasound, you may be asked to change into a gown – you will be covered during the procedure except for the area being examined. A layer of gel will be spread over the area to facilitate good contact, as this helps produce the best possible images. The ultrasound transducer is then placed over the specific area of your body.

FAQs

Are there any fasting or fluids requirements before getting an ultrasound?

Depending on the type of ultrasound required, you may need to fast from food and fluids. On the other hand, some ultrasound examinations require you to drink a significant amount of water prior to arriving so that your bladder is full. Speak to your doctor or Capital Radiology staff about any necessary preparations before your appointment.
