Radiopharmaceutical: 194 MBqs of Tc-99m-BrIDA (mebrofenin trimethylbromo-iminodiacetic acid). Technique: Two sets of 60 minutes dynamic images were acquired. The second set was acquired after the meal.
Findings:
There is good hepatic parenchymal uptake indicating good hepatic function. Subsequent images showed visualization of common bile duct at 14 minutes, gallbladder at 26 minutes and gut activity at 20 minutes of the study (normal). Post meal study showed good contraction of the gallbladder with good clearance of the radiotracer from the gallbladder with an estimated gallbladder ejection fraction of 92% (normal > 30). The ejection rate of gallbladder is measured as 2% per minute.
