Hida scan shows 17% function @ 20 min. no pain during exam 4.3 m of technetium 99m of choletec. 1.5mcg of cck. bilirubin is 1.5 enzymes good.

Not sure of results: Most laboratories determine ejection fraction, percentage of emptying at 30 or 60 minutes after injection of cck. I am not sure meaning of ejection fraction at 20 minutes.

Need more informatio: Hida with cck test is most accurate when performed to provide an ejection fraction at 1 hour post cck. The data you provide are atypical, preventing an accurate answer to your question. What is provided suggests a low gallbladder ejection fraction. Please discuss with your doctor, who may need to contact the nuclear medicine physician or radiologist (a physician as well) to clarify the result.
