Tc m Lidofenin is a compound used in nuclear medicine that is primarily administered intravenously for imaging purposes. Also known as technetium Tc 99m lidofenin, it belongs to the class of radiopharmaceutical agents. This compound consists of a radioactive isotope of technetium, specifically technetium-99m, which emits gamma radiation.
Tc m Lidofenin is commonly used in hepatobiliary scans, also called cholescintigraphy or HIDA scan, to evaluate the functionality of the liver, gallbladder, and biliary tract. During the procedure, the radiopharmaceutical is injected into the patient's vein and is taken up by the liver. From there, it is excreted into the biliary system, allowing for the visualization of the hepatic and biliary anatomy and any potential abnormalities.
The gamma radiation emitted by Tc m Lidofenin is detected by a gamma camera or scanner, which produces images based on the distribution and concentration of the radiopharmaceutical. The captured images help in diagnosing various hepatobiliary conditions such as gallstones, biliary obstruction, and inflammation of the liver.
Tc m Lidofenin has a relatively short half-life of approximately 6 hours, which allows for a sufficient imaging window while minimizing radiation exposure. It is considered safe when used under appropriate medical supervision and following proper administration guidelines.
In summary, Tc m Lidofenin is a radiopharmaceutical agent containing technetium-99m used for hepatobiliary scans for the evaluation of the liver, gallbladder, and biliary tract.
