technetium tc-99m etifenin

Technetium Tc-99m etifenin is a radiopharmaceutical agent used primarily for imaging studies of the liver and biliary tract. It is administered intravenously and accumulates in hepatocytes, allowing visualization of hepatic function and biliary excretion through gamma camera imaging. The compound contains the radioisotope technetium-99m, which emits gamma radiation detectable by nuclear medicine equipment. Its mechanism relies on selective uptake by functioning hepatocytes and subsequent excretion into the bile ducts, enabling assessment of liver function, gallbladder patency, and biliary tract integrity[2][4]. Technetium Tc-99m etifenin belongs to the class of organic compounds known as alpha amino acid amides[2].
