RADIOACTIVE COMPOSITION FOR HEPATOBILIARY SYSTEM SCINTIGRAPHY

摘要

Abstract Or the DisclosureA radioactive composition for the scintigraphicimaging of the hepatobiliary system is disclosed, thecomposition comprising a complex of 99mTc witha [2,6-di(lower)alkyl or 2,4,6-tri(lower)alkyl-acetanilido]-iminodiacetic acid having a total Or at least 3 carbonatoms in the alkyl groups, or a salt thereof, in sterileaqueous solution. In a preferred composition the complexcontains in addition a tin salt and is prepared directlyprior to use by reacting NaTcO4 with SnCl2 and the imino-diacetic acid.- 1 -
