After intravenous injection of 99mTc-EHIDA, it is rapidly taken up by liver parenchymal cells and excreted into the biliary system with bile. It can be used for imaging of the hepatobiliary system and has great diagnostic value for observation of extrahepatic bile duct obstruction, cholecystitis, cholangitis, bile duct atresia, bile duct cysts and post-operative observation of the biliary system. When bilirubin is 12mg/dl, the amount of this product entering the liver and the concentration in the bile are significantly reduced, and the biliary system is poorly visualized.

After intravenous injection, this product is rapidly cleared from the blood through glomerular filtration.

99mTc-phytate chelates with calcium ions in the blood to form insoluble 99mTc-phytate calcium colloidal particles with a diameter of 20-40nm, which are cleared from the blood by the reticuloendothelial system. 90% of them accumulate in the Kupffer cells of the liver, 2%-3% enter the spleen, and 8% enter the bone marrow. Therefore, the liver can be imaged, while the space-occupying, destructive or ischemic lesions in the liver cannot concentrate phytate calcium colloidal particles, so there will be areas of reduced radioactivity or defective areas, and the lesions can be displayed. When liver function is significantly reduced, compensatory concentration in the spleen and bone marrow increases, and sometimes even the lungs are also visualized. When the spleen is hyperactive, there are also varying degrees of visualization.
