From the case:
Normal HIDA scan

uniform radiotracer activity throughout the liver
prompt excretion into the bile ducts
radioactivity tracer activity was seen in the gallbladder after 10 min
ongoing accumulation of radiotracers over the 30-minute study
Normal cholescintigraphy (HIDA) scan.
Case Discussion
A normal HIDA scan was performed with 200 MBq of Tc-99m DISIDA given intravenously, and 30 minutes of imaging.
Acute cholecystitis and/or cystic duct obstruction can effectively be excluded since there is radiotracer activity in the gallbladder after 10 minutes and ongoing accumulation over the 30-minute study.
