Liver and Gallbladder - Ejection Fraction
Patient Information

What to expect

A technologist will explain the entire process to you prior to starting the exam.  He/she will also ask you some health history questions, which will help our radiologist interpret your exam.

A technologist will place an intravenous (IV) line in your arm.  You will be asked to lie flat on our imaging bed while our camera will be positioned over your abdomen area. 

You will be given an injection of a radiopharmaceutical that is filtered out by your liver and travels through your gallbladder and out your gastrointestinal (GI) tract. 

Depending upon how your gallbladder fills, we will either have you return for additional delayed images or we proceed with quantifying how your gallbladder contracts.

If you have any technical questions specific to this procedure, please don’t hesitate to ask the technologist at dosing time.  All clinical questions should be directed to your physician.

A report will be sent to your ordering physician.


How long will it take

Depending upon how your gallbladder functions, you could be with us anywhere from 60 – 90 minutes. 

In certain cases you might need to return at about 3 hours after your injection for additional images (usually 15 minutes of camera time).
