How Long Does a Diagnostic Imaging Appointment Take in Australia?
Appointment times vary depending on the type of imaging, preparation required and your individual circumstances. Knowing the difference between the scan itself and the total appointment time can help you plan your day with greater confidence.
There is no single appointment length for diagnostic imaging. As a general guide, a plain X-ray may take less than 15 minutes, an ultrasound around 20 minutes, a CT scan around 10 to 30 minutes and a DEXA bone density scan around 20 minutes. These are typical examination times rather than a guarantee of how long you will spend at the imaging centre.
How Long Does a Diagnostic Imaging Appointment Take?
The time required for a diagnostic imaging appointment depends on the type of examination, the area being assessed, whether preparation is needed and your individual circumstances.
It is also important to distinguish between the scan time and the total appointment time. A scan itself may be completed relatively quickly, but your visit can also include check-in, confirming your referral, preparation, positioning and any additional imaging required.
Check-In
Your appointment may begin with registration and confirmation of your referral and relevant details.
Preparation
Some examinations require specific preparation, while others require little or none.
Imaging
The examination itself can range from a few minutes to longer depending on the type of imaging.
Completion
Once the required images have been obtained, the examination is completed and the images proceed through the reporting process.
How Long Do Different Imaging Tests Take?
The following provides a general guide to examination times. Your actual appointment may take longer depending on the examination and any preparation or additional imaging required.
| Imaging Examination | Typical Examination Time | What Can Affect the Time? |
|---|---|---|
| General X-Ray | Usually less than 15 minutes | The body area being examined, number of images required and patient positioning. |
| Ultrasound | Around 20 minutes | The type of ultrasound, body area being assessed and any preparation required. |
| CT Scan | Around 10–30 minutes | The area being scanned, preparation, positioning and whether contrast is required. |
| DEXA Bone Density | Around 20 minutes | The areas being measured and the specific examination requested. |
| Liver Elastography | Varies | The examination protocol and individual circumstances. Confirm the expected appointment time with your imaging provider. |
| Ultrasound-Guided Procedures | Varies | The procedure being performed, preparation, clinical requirements and post-procedure instructions. |
Times are general guides only. They should not be treated as a guaranteed appointment duration.
How Long Does a General X-Ray Take?
A plain X-ray is generally one of the quicker diagnostic imaging examinations. Healthdirect states that the process for a plain X-ray takes less than 15 minutes.
The time can depend on which part of the body is being examined and how many images are required. You may be asked to sit, stand or lie down and remain still while the images are taken.
Your overall visit may take longer than the actual imaging because of check-in and other appointment requirements.

How Long Does an Ultrasound Take?
A typical ultrasound scan takes around 20 minutes, according to Healthdirect. However, the time can vary depending on the type of ultrasound and the area being examined.
During an ultrasound, gel is placed on the skin and a handheld transducer is moved over the area being assessed. You may be asked to change position during the examination.
Some ultrasound examinations have specific preparation requirements. If you have been given preparation instructions, follow those instructions carefully.

How Long Does a CT Scan Take?
A CT scan usually takes around 10 to 30 minutes, although the scan itself may be relatively quick. Healthdirect notes that much of the appointment time can involve getting ready for the scan.
You may need to lie on the CT table and follow breathing or positioning instructions. Depending on the examination, contrast material may also be required.
Preparation, positioning, checking relevant information and any requirements associated with contrast can add to the overall appointment time. Your imaging provider can tell you what to expect for your particular CT examination.

How Long Does a DEXA Bone Density Scan Take?
A DEXA or DXA bone density scan usually takes around 20 minutes. The examination uses low-dose X-rays to measure bone density, commonly at the lumbar spine and hip and, in some cases, the forearm.
You generally lie on a padded scanning table while the equipment takes measurements. DEXA is usually a straightforward examination, but you should still allow enough time for the complete appointment.

How Long Does Liver Elastography Take?
Liver elastography, including FibroScan, is a non-invasive examination that uses specialised ultrasound technology to assess liver stiffness.
Appointment duration can vary depending on the examination protocol and individual circumstances. Because a reliable general appointment time cannot be applied to every liver elastography examination, it is best to confirm the expected duration when booking.

How Long Does an Ultrasound-Guided Procedure Take?
Ultrasound-guided procedures can take longer than a standard ultrasound because they involve an additional clinical procedure as well as imaging guidance.
The duration depends on the particular procedure, preparation requirements and your individual circumstances.
If you have been referred for an ultrasound-guided procedure, ask the imaging provider how much time you should allow for the complete appointment.

What Is the Difference Between Scan Time and Appointment Time?
This is one of the most important things to understand when planning a diagnostic imaging appointment.
Scan Time
This refers to the time spent actually obtaining the required images or measurements.
Appointment Time
This can include check-in, preparation, positioning, the examination itself and any additional steps required for your appointment.
For example, a CT scan itself can be very quick, while the complete appointment may take longer because preparation and other steps are required.
Why Can Diagnostic Imaging Appointments Take Longer?
Even when an examination normally takes only a short amount of time, several factors can affect the duration of your appointment.
Type of Examination
Different imaging technologies and examinations have different processes and time requirements.
Preparation
Some examinations may require fasting, drinking water, a full bladder or other preparation before imaging.
Number of Images
The required number and type of images can influence how long an examination takes.
Additional Imaging
Additional images may sometimes be required to complete the examination appropriately.
Individual Circumstances
Your clinical situation, mobility and other relevant circumstances can affect positioning and appointment requirements.
Contrast Requirements
Some CT examinations may involve contrast material, which can add preparation or monitoring requirements.
How Can You Prepare for Your Imaging Appointment?
Following the preparation instructions provided by your imaging provider can help your appointment run as smoothly as possible.
- Check whether your examination requires fasting or other preparation.
- Bring your referral and any information requested by the imaging provider.
- Allow enough time for the complete appointment rather than only the estimated scan time.
- Wear appropriate clothing according to the instructions provided.
- Bring relevant previous imaging or reports if requested.
- Contact the imaging provider before your appointment if you are unsure about preparation.

How Much Time Should You Allow for Your Appointment?
If you need to plan work, school, childcare or travel around your appointment, it is sensible to allow some additional time beyond the estimated examination duration.
The exact amount of extra time depends on your examination. A simple X-ray may be relatively quick, while a CT examination involving preparation or an ultrasound-guided procedure may require more time.
If being on time for another commitment is important, ask the imaging provider how much time you should allow for the complete appointment, rather than asking only how long the scan itself takes.
Does the Appointment Time Include Getting Your Results?
Usually, the time you spend at the imaging centre is separate from the reporting process.
After the examination, the images are reviewed and a report is prepared by the appropriate medical imaging professional, such as a radiologist. The report is generally provided to the healthcare professional who referred you.
Your referring doctor or specialist can then explain the findings in the context of your symptoms, medical history and other clinical information.
The time required to prepare and communicate a report can vary and should not be confused with the time required to perform the imaging examination.
