You will also be be given an injection that makes your gallbladder contract. That part of the test measures how much bile is ejected from your gallbladder. That measurement is called the ejection fraction. IF I remember correctly, the neighborhood of 35% is normal, anything below about 20% or less indicates that the gallbladder isn't functioning as it should. If there are any small stones in the bile duct, you might feel nauseated for a short time immediately after the injection. If that happens, make sure you tell the radioloist as it's an important symptom to evaluate.
