The procedure

You will be assisted onto a table by a technologist.

Gallbladder Only

A small amount of radioactive material is injected into a vein in your arm.  You will be instructed to be still while images are made of the gallbladder every 10 minutes up to several hours depending on visualization of common bile duct, gallbladder and duodenum.  In some cases the patient may need to return the following day for delay imaging depending on how the gallbladder reacts to the isotope.

For those having CCK

Once the common bile duct, gallbladder and duodenum are an injection of CCK (cholecystokinin) is administered and additional images will be taken that may take several hours. CCK is a medication that causes the gallbladder to contract. During the injection, a person may experience abdominal cramping or pain and nausea, however this will pass quickly.
