Vicarious contrast material excretion (VCME) defines excretion of water-soluble contrast material in a way other than the norm, i.e. renal excretion.
The most common vicarious excretion of water-soluble contrast material is via the gall bladder. Although commonly associated with unilateral renal pathology, vicarious gallbladder excretion of contrast may be a normal variant in some individuals and does not in itself indicate renal pathology 1.
