What To Expect From A HIDA Scan In Australia
If you've been advised to undergo a HIDA scan Australia, you might be wondering what the procedure entails and what you can expect from it. A HIDA scan (hepatobiliary iminodiacetic acid scan) is a nuclear medicine imaging test used to evaluate the health and function of the gallbladder and bile ducts.
This diagnostic tool is essential for identifying a range of conditions, such as gallbladder inflammation, bile duct obstruction, and bile leakage. In this article, we’ll provide you with a detailed guide on what a HIDA scan involves, how to prepare for it, and what the results might indicate.

Understanding a HIDA Scan
A HIDA scan is a specialized nuclear medicine test that helps doctors assess the function of your liver, gallbladder, and bile ducts. It provides detailed imaging to detect blockages, inflammation, and other abnormalities in the hepatobiliary system.
How the HIDA Scan Works
During the procedure:
A small amount of radioactive tracer is injected into a vein in your arm.
The tracer travels to your liver, where bile-producing cells absorb it.
The tracer then moves with the bile through your bile ducts to your gallbladder and small intestine.
A gamma camera captures images of the tracer as it moves through your system, allowing doctors to identify any blockages or dysfunctions.
This non-invasive imaging technique provides valuable insights into how well your gallbladder and bile ducts are functioning.

Why You Might Need a HIDA Scan
Doctors may recommend a HIDA scan for various reasons, including:
Diagnosing Gallbladder Disease
If you experience symptoms such as severe abdominal pain, nausea, vomiting, or indigestion, a HIDA scan can help diagnose gallbladder disease or inflammation (cholecystitis).
Detecting Bile Duct Obstruction
A HIDA scan can identify blockages in the bile ducts, which may be causing jaundice, pain, or liver-related symptoms.
Post-Surgery Evaluation
After gallbladder surgery, a HIDA scan can determine if bile is flowing correctly from the liver to the small intestine.
Assessing Liver Function
The scan can also evaluate liver function and detect conditions such as bile leakage or abnormal bile flow.
If you have been experiencing digestive discomfort or unexplained abdominal pain, your doctor may recommend a HIDA scan to pinpoint the cause.

Preparing for a HIDA Scan
Preparation for a HIDA scan is relatively straightforward, but following the correct steps ensures accurate results.
1. Fasting Before the Procedure
You will likely need to fast for 4-6 hours before the test.
Fasting ensures that your gallbladder is empty, allowing for clearer imaging.
2. Medication Considerations
Inform your doctor about any medications or supplements you are taking.
Some medications, especially those affecting the gallbladder or liver, may need to be paused before the procedure.
3. Allergy Information
Notify your healthcare provider if you have allergies, particularly to medications, contrast dyes, or radioactive substances.
Following these preparation steps will help ensure that your HIDA scan results are as accurate as possible.

Step-by-Step Guide to the HIDA Scan Procedure
A HIDA scan typically takes 1-2 hours and involves the following steps:
1. Tracer Injection
A small amount of radioactive tracer is injected into a vein in your arm.
This is generally painless, though you might feel a slight prick.
2. Imaging Process
You will lie on a table while a gamma camera captures images of the tracer as it moves through your liver, gallbladder, and bile ducts.
It’s crucial to remain still during this time to ensure clear images.
3. Additional Medication (If Needed)
In some cases, you might receive a medication called cholecystokinin (CCK).
This medication makes the gallbladder contract and release bile, providing doctors with more information about its function.
4. Post-Scan Observation
After the scan, you can usually resume normal activities.
You might be asked to drink plenty of fluids to help flush the tracer from your system.
The procedure is non-invasive and painless, making it a safe and effective diagnostic tool.

Understanding Your HIDA Scan Results
The results of a HIDA scan can provide valuable insights into the functioning of your liver, gallbladder, and bile ducts.
Normal Results
Indicate that bile is moving freely from the liver to the gallbladder and into the small intestine.
Suggests that there are no blockages or abnormalities.
Abnormal Results
May suggest conditions such as gallbladder inflammation (cholecystitis), bile duct obstruction, or gallbladder dysfunction.
Your doctor will discuss any abnormal findings and suggest further diagnostic tests or treatment options if needed.
No. 6
Safety and Risks of a HIDA Scan
A HIDA scan is generally considered safe, with minimal risks.
Radiation Exposure
The amount of radioactive tracer used is very small and typically poses little risk to your health.
Special Considerations
Inform your doctor if you are pregnant, breastfeeding, or have kidney problems, as these conditions might require additional precautions.
Most patients experience no side effects, and the tracer naturally exits the body within a day.
Takeaways
Undergoing a HIDA scan in Australia is a straightforward and safe procedure that provides essential diagnostic information about your gallbladder and bile ducts. By understanding what to expect and how to prepare, you can ensure a smooth experience.
If you have any concerns or questions about the procedure, don’t hesitate to discuss them with your healthcare provider. With the right information and preparation, a HIDA scan can be a valuable step in diagnosing and treating digestive health issues.
