Though the hepatobiliary excretion of Technetium-99m ethylene dicysteine (99mTc-EC) is very low and usually does not effect image interpretation on routine posterior imaging, the possibility of visualization of the gall bladder should be kept in mind while reporting the 99mTc-EC scan especially, when anterior imaging is performed as in renal transplant patients.
Keywords: Gall bladder; technetium-99m ethylene dicysteine; vicarious visualization.
