Yes, most diagnostic imaging examinations in Australia require a referral from a registered healthcare practitioner, such as your General Practitioner (GP), specialist or another authorised medical professional.
A referral helps ensure you receive the most appropriate imaging examination for your condition and provides the radiologist with important clinical information needed to accurately interpret your images. Depending on the type of examination and individual circumstances, referral requirements may vary, so it's always best to check with your imaging provider if you're unsure.
Quick Summary
- Most diagnostic imaging examinations require a referral.

Introduction
If you've been asked to book a CT scan, ultrasound, X-ray, DEXA scan or another diagnostic imaging examination, you may be wondering:
"Do I actually need a referral before I can book?"
It's one of the most common questions patients ask before scheduling an appointment.
Understanding how referrals work can help make the booking process smoother, reduce unnecessary delays and ensure you receive the most appropriate imaging examination for your healthcare needs.
In Australia, referrals play an important role in connecting your healthcare provider with the radiologist. Rather than simply requesting a scan, a referral provides valuable clinical information about your symptoms, medical history and the reason the examination has been requested.
This information helps the radiologist prepare a clinically meaningful report that supports your healthcare provider in making informed decisions about your ongoing care.
Whether you're attending your first imaging appointment or have had previous examinations, this guide explains everything you need to know about medical imaging referrals in Australia.
What Is a Medical Imaging Referral?
A medical imaging referral is a request from a registered healthcare practitioner asking a diagnostic imaging provider to perform a specific imaging examination.
Think of it as a communication tool between your doctor and the radiologist.
Your referral usually includes important information such as:
- Your current symptoms
- Relevant medical history
- The reason the imaging examination has been requested
- The clinical question your doctor would like answered
- Previous imaging examinations that may need comparison
- Any additional information that may help the radiologist interpret your images accurately
This clinical information allows the imaging team to better understand your healthcare needs before your appointment even begins.
Why Are Referrals Important?
Many patients think a referral is simply paperwork needed to book an appointment.
In reality, it's an important part of providing safe, accurate and personalised healthcare.
A referral helps ensure that:
You Receive the Most Appropriate Imaging Examination
Different imaging examinations provide different types of information.
Your healthcare provider carefully selects the examination that is most appropriate for your symptoms and medical condition.
For example:
X-Rays
are commonly used to assess bones, joints and certain chest conditions.
Ultrasound
examinations provide real-time images of soft tissues, abdominal organs, blood vessels and pregnancy.
CT Scans
provide detailed cross-sectional images that can assist in investigating a wide range of medical conditions.
DEXA Scans
measure bone mineral density and help assess bone health.
Liver Elastography (FibroScan)
is a specialised examination used to assess liver stiffness in appropriate patients.
Ultrasound-guided procedures
combine imaging with minimally invasive techniques to assist certain medical procedures.
Choosing the right examination helps avoid unnecessary imaging and supports better clinical decision-making.
The Radiologist Understands Your Clinical History
Radiologists don't simply look at images—they interpret them in the context of your health.
Your referral provides valuable background information that helps the radiologist understand:
Why the examination has been requested
What symptoms you're experiencing
What your healthcare provider is trying to investigate
Whether previous imaging should be compared
This additional context contributes to a more informative and clinically relevant report.
Your Healthcare Team Receives Meaningful Results
Once your examination has been completed, the radiologist prepares a detailed report for your referring healthcare provider.
Your doctor then discusses the results with you, explains what they mean and recommends any further investigations, treatment or follow-up if required.
This collaborative approach helps ensure continuity of care and supports informed healthcare decisions.
Why Doesn't Every Patient Have the Same Imaging Examination?
It's common for patients to compare their experience with friends or family members.
For example:
"My friend had similar symptoms but was referred for a different scan."
This doesn't necessarily mean one examination is better than another.
Healthcare providers recommend imaging based on many individual factors, including:
Your symptoms
Your age
Your medical history
Previous imaging results
Clinical examination findings
The information needed to assist diagnosis
Because every patient is different, the most appropriate imaging examination may also differ.
Who Can Provide a Referral for Medical Imaging in Australia?
In Australia, referrals for diagnostic imaging can generally be provided by registered healthcare practitioners who are involved in your medical care.
Depending on your circumstances, your referral may come from:
General Practitioner (GP)
For many patients, a General Practitioner (GP) is the first point of contact when experiencing new symptoms or ongoing health concerns. After assessing your condition, your GP may recommend an imaging examination to help investigate the cause of your symptoms or support a diagnosis.
Medical Specialist
If you're receiving treatment from a specialist—such as an orthopaedic surgeon, gastroenterologist, endocrinologist or another medical specialist—they may refer you for imaging as part of your ongoing care or treatment planning.
Hospital or Emergency Department Doctor
If you've visited a hospital or emergency department, the treating doctor may arrange imaging examinations to help assess injuries or medical conditions that require further investigation.
Other Authorised Healthcare Practitioners
Depending on Australian regulations and the type of imaging examination required, referrals may also be provided by other authorised healthcare practitioners where appropriate.

CT Scans
Ultrasound Examinations

Can I Book an Imaging Appointment Without a Referral?
This is one of the most frequently asked questions by patients.
The answer depends on the type of imaging examination you're having and your individual circumstances.
While many diagnostic imaging examinations require a referral, some services or booking arrangements may differ depending on the examination and payment method.
If you're unsure whether you need a referral, it's always best to contact the imaging provider before booking your appointment. A quick conversation with the clinic can help avoid delays and ensure you have everything required for your visit.
Why Can't I Simply Request Any Scan I Want?
It might seem easier to choose an imaging examination yourself, but diagnostic imaging is most effective when it's requested based on your clinical needs.
Different imaging technologies provide different types of information, and not every examination is suitable for every condition.
Your healthcare practitioner considers several factors before recommending an imaging examination, including:
- Your symptoms
- Your medical history
- Physical examination findings
- Previous imaging results
- The clinical question that needs answering
Requesting the most appropriate examination helps avoid unnecessary imaging and supports safe, effective patient care.
Does a Referral Mean Something Serious Is Wrong?
Not at all.
Many patients become anxious when they're referred for diagnostic imaging, assuming it means their doctor is expecting a serious diagnosis.
In reality, referrals are a routine part of modern healthcare.
Doctors often request imaging to:
- Investigate symptoms more thoroughly.
- Confirm or rule out possible conditions.
- Monitor an existing medical condition.
- Assess recovery after treatment or injury.
- Guide further medical management.
In many cases, imaging provides reassurance by helping your healthcare provider better understand what's causing your symptoms.
What Information Is Included on a Referral?
A referral usually contains important details that help the radiologist understand your healthcare needs.
This may include:
- Your name and date of birth
- Contact details
- The requested imaging examination
- Your symptoms
- Relevant medical history
- Previous surgeries or injuries (where relevant)
- The reason your healthcare provider has requested imaging
- Details of your referring practitioner
Providing accurate clinical information helps the radiologist prepare a report that supports your healthcare provider in making informed decisions about your care.
Patient Tip
Before attending your appointment, check that you have:
This may include:
- Your referral (if required)
- Medicare card (if applicable)
- Private health insurance details (if applicable)
- Any previous imaging reports or scans requested by your healthcare provider
- dentification if requested by the clinic
Bringing the correct documentation can help make your appointment as smooth and efficient as possible.
What Happens After You Receive Your Referral?
Once your healthcare practitioner has provided a referral, the next steps are usually straightforward.
Step 1: Choose Your Diagnostic Imaging Provider
In most cases, you can choose the diagnostic imaging provider that best suits your location and appointment preferences.
When selecting a provider, you may wish to consider factors such as:
- Convenient location
- Appointment availability
- Services offered
- Experienced radiologists and imaging professionals
- Modern imaging technology
- Clear communication and patient support
Step 2: Book Your Appointment
Once you've selected your preferred imaging provider, you can book your appointment.
Depending on the clinic, appointments may be made by:
- Phone

- Referral from your healthcare provider
- In-person at the clinic
When booking, the clinic may ask for information such as:
- Your referral details
- Preferred appointment time
- Contact information
- Medicare or private health insurance details (where applicable)
If any preparation is required before your examination, you'll usually be informed at the time of booking.
Step 3: Prepare for Your Examination
Preparation varies depending on the type of imaging examination.
For example:
- Some ultrasound examinations may require a full bladder.
- Certain CT examinations may involve specific preparation instructions.
- Some examinations may not require any preparation at all.
Following the preparation instructions provided by your imaging provider helps ensure the best possible image quality and may reduce the need for repeat examinations.
If you're unsure about how to prepare, don't hesitate to contact the clinic before your appointment.
What Should You Bring to Your Appointment?
Before leaving for your appointment, it's helpful to have everything you need.
Your imaging provider may ask you to bring:
- Your referral (if required)
- Medicare card (if applicable)
- Private health insurance details (if applicable)
- Previous imaging reports or scans, if requested
- A list of current medications if relevant to your examination
Arriving a few minutes early can also help complete any required paperwork before your appointment begins.
What Happens During Your Imaging Appointment?
Every imaging examination is different, but the process is generally designed to be as comfortable and efficient as possible.
When you arrive, a member of the imaging team will:
- Confirm your personal details.
- Review your referral.
- Explain the examination.
- Answer any questions you may have.
- Provide any final preparation instructions.
Depending on the examination, you may be asked to change into a gown or remove certain items such as jewellery or metal accessories.
The imaging professional performing your examination will guide you through each step to help you feel informed and comfortable.
What Happens After Your Scan?
Many patients assume they will receive their results immediately after the examination.
However, in most cases, your images first need to be carefully reviewed by a radiologist.
After your examination:
- Your images are securely processed.
- A specialist radiologist reviews the images.
- A detailed diagnostic report is prepared.
- The report is sent to your referring healthcare practitioner.
- Your doctor discusses the findings with you and explains any recommended next steps.
This process helps ensure that your results are interpreted accurately and within the context of your overall health.
Will I Receive My Results on the Same Day?
The timeframe for receiving imaging results can vary depending on:
- The type of examination performed
- The clinical urgency
- The reporting process
- Your referring healthcare provider's arrangements
In most cases, your results are sent directly to the healthcare practitioner who requested the examination. They are then responsible for discussing the findings with you and answering any questions you may have.
If you're unsure when to expect your results, your imaging provider can usually give you an estimated timeframe.
