HIDA scan in Chennai
A Hepatobiliary (HIDA) scan is an imaging procedure that is used to evaluate the function and anatomy of the liver, gallbladder, and bile ducts. It involves the injection of a radioactive tracer called technetium-99m (Tc-99m) hepatic iminodiacetic acid (HIDA), which is taken up by the liver and excreted into the bile, allowing visualization of the biliary system.
What is the need for the study?
The HIDA scan is performed to:
- Assess liver function and bile flow in patients with suspected liver or biliary tract disorders, such as cholecystitis (inflammation of the gallbladder), biliary obstruction, or bile leaks.
- Diagnose conditions affecting the biliary system, such as gallstones, bile duct strictures, or bile duct tumors.
- Evaluate the function of the gallbladder and assess for gallbladder dysfunction, such as biliary dyskinesia.
This study helps healthcare providers make accurate diagnoses and develop appropriate treatment plans to manage liver and biliary disorders and optimize patient outcomes.
How do I prepare?
Preparation for a HIDA scan may include:
- Fasting: You may be instructed to fast for a period before the scan, typically for several hours, to ensure an empty stomach for accurate imaging.
- Medication: Inform your healthcare provider about any medications you are taking, as certain medications may need to be temporarily stopped before the scan.
- Hydration: Drink plenty of fluids before the scan to ensure adequate hydration, which can help improve the distribution of the radioactive tracer used in the procedure.
Your healthcare provider will provide specific instructions on how to prepare for the HIDA scan based on your individual circumstances.
How is this scan performed?
During a HIDA scan:
- Radiotracer Injection: A small amount of the radioactive tracer technetium-99m (Tc-99m) HIDA is injected into a vein in your arm.
- Imaging: A gamma camera is used to acquire images of the abdomen over a period of time, typically several hours. The camera detects the gamma rays emitted by the radioactive tracer, allowing visualization of the liver, gallbladder, and bile ducts as the tracer is taken up and excreted.
- Functional Assessment: The images obtained from the scan are analyzed to assess liver function, bile flow, and the presence of any abnormalities or blockages in the biliary system.
What should I do after the scan?
After the HIDA scan:
- Resume Normal Activities: You can usually resume your normal activities immediately after the scan.
- Follow-Up: Attend any scheduled follow-up appointments with your healthcare provider to review the results of the scan and discuss further management, if necessary.
Are there any risks in the study?
HIDA scans are generally considered safe and non-invasive. The amount of radiation exposure from the radioactive tracer used in the scan is minimal and poses little risk to most patients. However, like any other medical procedure involving radiation, there is a slight chance of allergic reactions or adverse effects.
Your healthcare provider will discuss the potential risks and benefits of the HIDA scan with you and address any concerns you may have before proceeding with the procedure.
It’s essential to follow all instructions provided by your healthcare provider and communicate any symptoms or concerns you experience during or after the HIDA scan. Your healthcare team is here to support you throughout the process and ensure the best possible outcomes for your liver and biliary health.
