99M TC-LABELED RADIOACTIVE DIAGNOSTIC AGENT ANS A NON-RADIOACTIVE CARRIER COMPOSTITION

摘要

A 99mTc-labeled radioactive diagnostic agent, prepared by contacting 99mTc in the form of a pertechnetate with a non-radioactive carrier comprising pyridoxal or salt thereof, a stannous salt and an alpha -amino acid not having any hydrophilic functional group dissolved in an aqueous medium. This diagnostic agent is suitable for the examination of hepatobiliary ducts due to its smooth transfer through the hepatobiliary ducts as well as its high stability and non-toxicity.
