Gallbladder & bile ducts
HIDA scans can help assess gallbladder function and bile flow, including when a blockage or leak is suspected.
Hepatobiliary & Gastrointestinal Imaging
Functional imaging of the liver, gallbladder and digestive tract.
Hepatobiliary scans, gastric emptying studies, bleeding localisation and liver imaging to assess how these organs work and where problems arise.

About Hepatobiliary & GI Imaging
Nuclear medicine follows a tracer as it moves through the liver and bile ducts, or as a meal passes through the stomach and gut. This shows how well these organs work, which a structural scan cannot always do.

HIDA scans show bile flow and gallbladder function, and liver and spleen studies assess the organs and their blood supply.
Gastric emptying, reflux and transit studies show how food and fluid move, and bleeding and Meckel’s scans help locate a source of bleeding.
Your doctor will advise which study is appropriate for your clinical question.

When It May Help
Your doctor recommends imaging based on your symptoms and clinical needs.

HIDA scans can help assess gallbladder function and bile flow, including when a blockage or leak is suspected.
Gastric emptying studies measure how quickly a meal leaves the stomach.
Bleeding and Meckel’s diverticulum scans can help find the source when gastrointestinal bleeding is suspected.
MAA studies assess liver blood supply and lung shunting before transarterial radioembolisation (TARE).

Your Visit, Step by Step
What happens during a gamma camera or SPECT-CT visit.
The team reviews your referral and relevant medical history.
A tracer is administered, followed by a resting period.
You lie on the scanner table while images are acquired.
The team explains the next steps and reporting process.
The exact process depends on your scan and clinical needs.
Before Your Visit
Bring the referral and earlier ultrasound, CT, endoscopy and blood test reports where available.
Hepatobiliary and gastric emptying studies typically need fasting beforehand, and the duration depends on the study. The team will give you exact instructions.
Some medicines, such as those that change gut movement, can affect these studies. The team will advise you, and you should not stop any on your own.
Mention recent barium studies, endoscopy, surgery or other scans, as they can affect the study.
Let the team know before your appointment.

Preparation varies by study. Contact the team if you are unsure about any instruction.

For Referring Clinicians
A short guide for referring doctors.
The clinical question, relevant history, biochemistry or histology where available, and previous imaging reports.
The studies listed on this page are chosen to match the clinical question. If you are unsure which is most appropriate, we are happy to help.
Studies are reported by a nuclear medicine physician, and findings can be discussed with the referring team.
Call or write before referring if you would like to discuss suitability or timing.

FAQs
Answers to questions patients often ask before a liver or digestive study.
For many of these studies an empty stomach is needed so the tracer moves normally and the images can be read correctly. The team will tell you how long to fast for your study.
You eat a small test meal that contains a tracer, and images are taken over a period of time to see how quickly the meal leaves the stomach. The team will explain the timing for your study.
It follows a tracer through the liver and bile ducts to show how bile flows and whether the gallbladder works normally. Your doctor decides when it is needed.
The time varies by study. The team will tell you what to expect when arranging your appointment.
Nuclear medicine studies use a small amount of radioactivity and the team follows radiation safety practices. Tell the team if you are pregnant or breastfeeding, or think you might be.
Your referring doctor will usually discuss the findings with you. Contact the team about when your report will be available.
