What is an ultrasound?
Ultrasound is a non-invasive imaging technique that uses high-frequency sound waves to produce real-time images of organs, blood vessels, and soft tissues. Because ultrasound does not use ionising radiation, it is often a first-line imaging choice for many symptoms, particularly for assessing the abdomen, pelvis, and musculoskeletal structures.
A sonographer performs the scan using a hand-held probe and water-based gel. The images are interpreted by a radiologist, who sends a written report to your referring GP. The procedure is usually painless, though some probes may be pressed firmly into tender areas to get a clear image.
When an ultrasound is ordered
Your GP may recommend an ultrasound for a range of reasons, including unexplained abdominal pain, suspected gallbladder or kidney conditions, pelvic symptoms, abnormal menstrual bleeding, soft-tissue lumps, suspected tendon injuries, or pregnancy dating and screening. Ultrasound is also used to assess the thyroid, breasts, and blood vessels.
For musculoskeletal problems, ultrasound can show soft-tissue structures such as muscles, tendons, and bursae, making it useful for conditions like rotator cuff injuries or tendinopathy. X-rays and MRI may be chosen instead depending on the clinical picture, and your GP will discuss which test is most appropriate.
How to get an ultrasound referral online
Book a telehealth consultation with a NewDoc GP and discuss your symptoms, history, and any previous imaging. If your GP determines an ultrasound is clinically appropriate, the referral will be emailed to you after the appointment. You can then book at any radiology or imaging centre in Australia.
The consultation is bulk billed for eligible Medicare patients, and an ultrasound performed with a valid GP referral is eligible for a Medicare rebate. Many ultrasounds are bulk billed at participating imaging providers, though some may charge a gap fee. The imaging referral overview page provides more general information on how telehealth imaging referrals work.
What to expect at the imaging provider
You can book your ultrasound at major providers such as I-MED Radiology and Sonic Healthcare-affiliated practices, as well as at many local radiology clinics. Book online or by phone, and confirm any preparation at the time of booking. Bring your referral, Medicare card, and any previous imaging.
On the day, the sonographer will explain the scan, apply gel to the area, and move the probe to capture images. Most ultrasounds take 15 to 45 minutes. You can usually resume normal activities straight afterwards. If a follow-up scan or additional view is needed, your imaging centre will advise you.
Understanding results
The radiologist's report is sent electronically to your NewDoc GP, usually within a few business days. Your GP will review the findings in the context of your symptoms and other tests and contact you to discuss what they mean.
Depending on the results, your GP may recommend further investigations, a specialist referral, lifestyle advice, or treatment, subject to clinical appropriateness. Not every finding requires treatment, and your GP will explain which findings are significant and which are likely incidental.
When telehealth may not be suitable
Telehealth works well for discussing symptoms, arranging ultrasound referrals, and reviewing results. However, if you have severe or sudden abdominal pain, heavy bleeding, signs of infection with fever, or an injury that may need immediate attention, you should seek in-person or emergency care. Book a bulk billed telehealth consultation to discuss whether an ultrasound is right for your situation.
