Hi doctors, was just wondering what is considered a high gallbladder ejection fraction during a hida scan?

Usually normal: Hyperkinetic or hyperactive gallbladder is not generally accepted as a diagnosis. A small group of patients (63) was symptomatic with cck infusion with greater than 80% ejection fraction. 28 of these patients underwent removal of gall bladder. 97% of these 28 patients showed improvement in symptoms following surgery. . More published retrospective and prospective studies needed.
