How do you prepare for a hida scan? A hepatobiliary iminodiacetic acid (HIDA) scan, also known as a hepatobiliary scan or cholescintigraphy, is a nuclear medicine imaging procedure used to evaluate the function of the gallbladder, liver, and bile ducts. This scan is particularly useful in diagnosing conditions such as gallstones, biliary obstruction, and gallbladder dysfunction. To ensure the best results and minimize discomfort during the procedure, it is essential to follow the proper preparation steps. In this article, we will discuss the necessary preparations for a HIDA scan and what you can expect during and after the procedure.
Before the HIDA scan, your doctor will provide you with specific instructions. Generally, you should avoid eating or drinking anything for at least 4-6 hours prior to the scan. This fasting period is crucial to ensure that your gallbladder contracts properly during the procedure. Additionally, you may be asked to stop taking certain medications, such as antacids or blood thinners, as they can affect the scan’s results.
On the day of the scan, wear comfortable clothing and remove any metal objects, such as jewelry or piercings, as they can interfere with the imaging equipment. It is also important to inform the technologist performing the scan about any allergies you may have, as well as any previous medical procedures or radiation exposure.
During the HIDA scan, you will be asked to lie on a flat table. The technologist will apply a small amount of radioactive tracer, called technetium-99m, to your skin or inject it into a vein. This tracer will travel through your bloodstream and accumulate in your gallbladder, liver, and bile ducts. As the tracer accumulates, a series of images will be taken to monitor its movement and function.
After the scan, you can resume your normal activities and diet. However, it is essential to drink plenty of fluids to help flush the tracer from your body. You may experience some mild discomfort or bloating due to the accumulation of the tracer in your gallbladder, but this should resolve within a few hours.
It is important to note that the HIDA scan is a safe procedure, with minimal radiation exposure. However, if you are pregnant or breastfeeding, inform your doctor, as the radiation may pose a risk to your baby. Additionally, if you have kidney problems or are on dialysis, discuss the risks and benefits of the scan with your healthcare provider.
In conclusion, preparing for a HIDA scan involves fasting, avoiding certain medications, and informing the technologist about any allergies or medical conditions. By following these steps, you can ensure the best possible results and a comfortable experience during the procedure. Remember to drink plenty of fluids after the scan to help flush the tracer from your body. If you have any concerns or questions about the HIDA scan, do not hesitate to consult with your healthcare provider.
