HIDA in Hyderabad: Gallbladder and Bile Duct Function Test

HIDA Scan in Hyderabad: Gallbladder and Bile Duct Function Test

A HIDA scan is a specialized nuclear medicine imaging test used to evaluate the liver, gallbladder, bile ducts and the flow of bile through the hepatobiliary system. It is also known as a hepatobiliary scan or cholescintigraphy.

Unlike imaging tests that mainly show the structure of the gallbladder and bile ducts, a HIDA scan helps assess how these organs are functioning and how bile moves through the system.

For patients experiencing unexplained right upper abdominal pain, suspected gallbladder problems or concerns related to bile flow, a HIDA scan may be recommended by a doctor as part of the diagnostic evaluation.

What Is a HIDA Scan?

HIDA stands for hepatobiliary iminodiacetic acid. During the examination, a small amount of radiotracer is administered, usually through an intravenous injection.

The tracer is taken up by the liver and excreted into bile. A specialized gamma camera then follows the movement of the tracer through:

• Liver
• Bile ducts
• Gallbladder
• Small intestine

This allows nuclear medicine specialists to assess the movement of bile and the functional activity of the hepatobiliary system.

Why Is a HIDA Scan Done?

A HIDA scan may be recommended when a doctor needs more information about gallbladder or bile duct function.

Common reasons include:

Suspected Acute Cholecystitis

A HIDA scan can help evaluate whether the gallbladder is filling normally. It may be useful when acute inflammation of the gallbladder is suspected, particularly when other imaging findings are inconclusive.

Gallbladder Function Assessment

The examination can provide functional information about the gallbladder. In selected cases, a medication may be used during the scan to stimulate gallbladder contraction and help assess its emptying.

Bile Duct Obstruction

A HIDA scan can help evaluate whether bile is flowing normally through the bile ducts into the intestine.

Bile Leakage

After certain gallbladder or abdominal surgeries, a HIDA scan may be used to evaluate suspected leakage of bile.

Abnormal Hepatobiliary Function

When symptoms and other investigations suggest a hepatobiliary problem, a HIDA scan may provide additional functional information.

What Does a HIDA Scan Show?

A HIDA scan can provide information about:

• Uptake of the radiotracer by the liver
• Passage of bile from the liver
• Filling of the gallbladder
• Movement of bile through the bile ducts
• Passage of bile into the small intestine
• Gallbladder emptying in selected protocols
• Possible bile leakage

The results are interpreted together with symptoms, medical history, laboratory tests and other imaging findings.

HIDA Scan Procedure

The procedure is generally performed in a nuclear medicine department.

Step 1: Patient Preparation

The patient may be asked to fast for a specified period before the examination. The exact preparation can vary depending on the clinical indication and the protocol being used.

It is important to follow the instructions provided by the nuclear medicine team.

Step 2: Radiotracer Injection

A small amount of a suitable radiotracer is administered through an intravenous injection.

Step 3: Imaging

The patient lies comfortably while a gamma camera is positioned to capture images of the abdomen.

The camera follows the radiotracer as it moves through the liver, gallbladder and bile ducts.

Step 4: Additional Imaging

Depending on the reason for the examination, additional imaging time or a medication that stimulates gallbladder contraction may be required.

The total duration can therefore vary between patients.

Is a HIDA Scan Painful?

The imaging itself is generally painless.

The main discomfort may be the brief needle prick associated with intravenous injection. During certain protocols, patients may experience temporary abdominal discomfort or other sensations when gallbladder contraction is stimulated.

The medical team monitors the patient throughout the examination.

How Long Does a HIDA Scan Take?

The duration depends on how quickly the radiotracer moves through the hepatobiliary system and whether additional functional assessment is required.

Some examinations may take around one to two hours, while certain cases can require longer imaging.

Patients should therefore plan sufficient time rather than expecting the scan to have a fixed duration.

HIDA Scan Preparation

Preparation instructions are important because food intake and certain medications can affect gallbladder contraction and the accuracy of the examination.

Depending on the protocol, patients may be instructed to:

• Fast for a specified period before the scan
• Avoid eating immediately before the examination
• Inform the team about current medications
• Inform the team about recent procedures or surgeries
• Follow any specific instructions provided by the nuclear medicine department

Do not stop prescribed medicines unless your doctor or nuclear medicine team specifically instructs you to do so.

HIDA Scan and Gallbladder Function

One of the important advantages of hepatobiliary imaging is that it can provide functional information.

For selected patients, a medication may be administered during the examination to encourage the gallbladder to contract. This allows assessment of how effectively the gallbladder empties.

This information may be useful when evaluating certain gallbladder functional disorders.

HIDA Scan vs Ultrasound

An abdominal ultrasound is commonly used as an initial investigation for gallbladder-related symptoms.

Ultrasound can provide detailed structural information, including gallstones, gallbladder wall changes and bile duct abnormalities.

A HIDA scan provides different information by following the movement of a radiotracer and evaluating bile flow and hepatobiliary function.

In some situations, both examinations may be recommended because they provide complementary information.

HIDA Scan vs CT Scan

CT provides detailed anatomical images of the abdomen and can identify a wide range of structural abnormalities.

HIDA scanning is a nuclear medicine examination focused on hepatobiliary function and bile movement.

The choice between these tests depends on the patient's symptoms, clinical question and previous investigation results.

Is a HIDA Scan Safe?

HIDA scanning uses a small amount of radioactive tracer for diagnostic imaging. The amount is carefully selected for the examination.

Nuclear medicine procedures are performed using established protocols designed to minimize unnecessary radiation exposure.

Before the examination, inform the medical team if you are:

• Pregnant or think you may be pregnant
• Breastfeeding
• Taking regular medications
• Recently undergone abdominal surgery or another relevant procedure

The nuclear medicine team can provide specific instructions based on your situation.

What Happens After the HIDA Scan?

Most patients can return to their normal routine after the examination unless their doctor gives different instructions.

The radiotracer naturally leaves the body through normal biological processes. Patients may receive specific hydration or post-procedure instructions depending on the examination protocol.

Your images are reviewed by the appropriate medical specialist, and the final findings are interpreted in the context of your clinical history.

When Should You Talk to a Doctor?

A doctor may consider hepatobiliary imaging when symptoms suggest a gallbladder or bile-flow problem, especially when other investigations do not provide enough functional information.

Symptoms that may require medical evaluation include:

• Persistent or recurrent right upper abdominal pain
• Pain after eating
• Nausea or vomiting
• Unexplained digestive symptoms
• Fever associated with abdominal pain
• Yellowing of the skin or eyes
• Suspected bile duct problems
• Symptoms following gallbladder or abdominal surgery
