- Normal filling of the gallbladder
- Unobstructed passage of radiotracer through the cystic duct, bile duct and into the duodenum
- Gallbladder ejection fraction of 72% (Normal > 33% for this protocol)
Normal cholescintigraphy (HIDA) scan with no evidence of cholecystitis or gallbladder dysfunction
Normal HIDA scan performed with 75 MBq of Tc-99m DISIDA given intravenously, with imaging commenced at 1 hr and an oral fat-rich meal given to stimulate gallbladder contraction. Radiotracer activity in the gallbladder is measured over time as the gallbladder empties through the cystic duct, allowing gallbladder function to be assessed. A normal gallbladder ejection fraction under this protocol is > 33%.
