Radiopharmaceutical: 194 MBqs of Tc-99m BrIDA (mebrofenin trimethylbromo-iminodiaceticacid) injected IV as per protocol. Post-injection, immediate dynamic images of the liver and the gallbladder were acquired for 60 minutes. Fatty meal was given at this point and another set of dynamic images for 60 minutes post-meal were acquired to look for the contraction of the gallbladder.
Description: Scan shows well-outlined liver with good perfusion of the tracer throughout the liver parenchyma. The gallbladder is visualized at the 10th minute of the study with the visualization of the intestine thereafter. Progressive accumulation of the tracer is noted in the gallbladder until the 60th minute of the study. Post-fatty meal images show partial contraction of the gallbladder with ejection fraction of 20% (normal > 30%). Significant amount of tracer is noted in the gut at the end of the study suggestive of no obstruction in the biliary tract.
