NCIt definition : A radioconjugate composed of the iminodiacetic acid derivative mebrofenin bound to
an isotope of the synthetic element technetium (Tc). Upon administration and rapid
clearance from the circulation, technetium Tc 99m mebrofenin is secreted into the
hepatobiliary system, emitting gamma rays that are detectable with planar scintigraphy
or single photon emission computer tomography (SPECT). Mebrofenin has no pharmacological
effect at the recommended dosage for diagnostic imagining.;
