Hepatobiliary Scan (Disida Scan)

What is a Hepatobiliary scan?
A hepatobiliary scan is a nuclear medicine study that shows the function of the gallbladder.

Why did the doctor order the scan for me?
This scan is usually ordered when a patient is experiencing abdominal discomfort and/or food intolerances.  This includes nausea, vomiting and bloating.

What do I need to do to prepare for the scan?
You will not be allowed to eat or drink six hours prior to scan.  You also will be asked to not take any medications that contain morphine, Demoral or other opiates, 24 hours before the scan. Please bring your insurance card(s), driver's license and co-pay.

What should I expect when I arrive at the hospital?
You will first need to check in and register at the Radiology Registration desk that is located past Mercy Gift Shop on the left.  At that time your personal and insurance information will be updated.  Once you are registered, you will be asked to sit in the waiting area. A technologist will call you and take you to the Nuclear Medicine area. 

Who will be in the scaning room with me?
Your family is welcome to accompany you during the explanation of the test, but will be asked to return to the waiting room during the actual scan.  A nuclear medicine technologist will perform your scan.

What will I experience during the scan?
The technologist will ask you some questions regarding your medical history and the problems that you are experiencing.  He or she will start an IV and give an injection of a small amount of a radioactive tracer.  There are no side effects to this injection.  Then, the technologist will take pictures of your gallbladder for one hour.  After the first hour another medication will be given in order to further assess the function of your gallbladder. Pictures will then be taken for an additional 30 minutes. The symptoms you have been experiencing may or may not be simulated from the injection of the medication.

If your gallbladder does not show up in the first hour, we may need to give you a dose of morphine. If this happens, you will not be able to drive for 24 hours. You will need to call for a ride home.

What do I need to do after the scan?
Following your hepatobiliary scan you can return to normal activities. 

When will I get results of the scan?
The results will be available at your doctor's office within two to three days.  Some doctors will schedule an appointment to give you the results.  If you do not have an appointment, please call you doctor's office for your results.  If you have any problems receiving you results, you may call the Nuclear Medicine Department for assistance. - this needs to be changed
