A member asked:
My hida scan had a first ejection rate of 12% then they doubled the cck dose and ran it again and the second was 46%. which is the "correct" reading?

Unsure technique: Usually standard dose of cck for gall bladder ejection determination intravenous injection of 0.02 mg/kg over 30–60. Maybe original dosing was not properly calculated. Normal ejection fraction in adult is usally above 35%.From information do not know dose injected.

What is the Correct?: Odd exam. There is a shortage of cck, did they use a lower then normal dose the first time. The gb ef is not normally dose dependent if used appropriately. I believe that the 45% gbef is probably the correct measure.

Your hida scan is abnormal, with a low ejection fraction and reproduction of symptoms with the cck injection. What does this mean in layman's terms?
