Safety of Radiopharmaceuticals in HIDA Scans
- The safety of radiopharmaceuticals used in Hepatobiliary Iminodiacetic Acid (HIDA) scans is not directly addressed in the provided studies 1, 2, 3, 4, 5.
- However, the studies suggest that HIDA scans are a valuable diagnostic tool for various hepatobiliary diseases, including acute cholecystitis, biliary obstruction, and chronic gallbladder disease 1, 2, 3, 4, 5.
- The radiopharmaceuticals used in HIDA scans, such as Tc-99m-HIDA, are extracted by hepatocytes in the liver and cleared through the biliary system, similar to bilirubin 1.
- The studies do not report any significant adverse effects or safety concerns associated with the use of these radiopharmaceuticals 1, 2, 3, 4, 5.
Diagnostic Applications of HIDA Scans
- HIDA scans are used to diagnose various hepatobiliary diseases, including acute cholecystitis, biliary obstruction, and chronic gallbladder disease 1, 2, 3, 4, 5.
- The scans can detect high-grade biliary obstruction prior to ductal dilatation and can confirm biliary leakage postcholecystectomy and hepatic transplantation 1.
- HIDA scans can also aid in the diagnosis of partial biliary obstruction due to stones, biliary stricture, and sphincter of Oddi obstruction 1.
