Understanding HIDA Scans: Patient Information and Tips
HIDA scans, also known as hepatobiliary iminodiacetic acid scans, are medical imaging tests that help diagnose problems in the liver, gallbladder, and bile ducts. These tests involve injecting a special dye into the bloodstream, which then travels to the liver and other organs. As the dye moves through these organs, a special camera takes pictures, allowing doctors to see how well the liver and other organs are functioning.
If you’re scheduled for a HIDA scan, you may be feeling nervous or unsure about what to expect. Here’s what you need to know about this diagnostic procedure, along with some tips for preparing for it and getting the most accurate results.
What Is a HIDA Scan?
A HIDA scan is a type of medical imaging test that uses a radioactive tracer to provide images of the liver, gallbladder, and bile ducts. This type of test is often used to diagnose problems such as blockages, infections, or tumors in these organs.
During the test, a radiologic technologist will inject a small amount of radioactive dye into your bloodstream. The dye will travel to your liver and gallbladder, where it will be taken up by the cells. Then, a special camera will be used to capture images as the dye makes its way through your liver and gallbladder and into your small intestine.
The test takes approximately 90 minutes to complete, and most people experience no discomfort or side effects.
Preparing for a HIDA Scan
Before your HIDA scan, your healthcare provider will provide you with detailed instructions on how to prepare. These instructions may include:
– Fasting for several hours before the test
– Drinking plenty of fluids to help flush the dye out of your system
– Avoiding certain medications that may interfere with the test results
– Bringing a list of all medications you’re currently taking
It’s important to follow these instructions carefully to ensure that the test results are accurate.
What to Expect During the Test
During the HIDA scan, you’ll lie on a table while the radiologic technologist injects the radioactive dye into your bloodstream. You’ll need to lie still for approximately 90 minutes while the camera takes pictures of your liver and gallbladder. The technologist may ask you to change positions or hold your breath briefly to get the best possible images.
After the test, you may be asked to wait for a short period of time to ensure that you’re not experiencing any side effects. Then, you’ll be free to go about your day as usual.
Interpreting the Results
Once the HIDA scan is complete, a radiologist will review the images to determine if there are any problems with your liver, gallbladder, or bile ducts. Your healthcare provider will then review the results with you and discuss any next steps if necessary.
If your scan shows any abnormalities or blockages, your healthcare provider may recommend additional tests or treatments to address the underlying problem.
Tips for a Successful HIDA Scan
To ensure that your HIDA scan produces the most accurate results, it’s important to follow these tips:
– Follow all instructions provided by your healthcare provider
– Drink plenty of fluids before and after the test to help flush the dye out of your system
– Wear comfortable, loose-fitting clothing to the test
– Relax and try to stay still during the test to ensure clear images
– Inform your healthcare provider if you’re pregnant or breastfeeding, as you may need to postpone the test
By following these tips, you can help ensure that your HIDA scan is successful and provides accurate information about your liver, gallbladder, and bile ducts.
Conclusion
If you’re scheduled for a HIDA scan, it’s normal to feel nervous or unsure about what to expect. However, by understanding what the test involves and following the tips outlined above, you can help ensure that the process goes smoothly and provides accurate results. If you have any questions or concerns about the test, don’t hesitate to speak with your healthcare provider.
