Sequential scintiphotography with technetium-99m pyridoxylideneglutamate in the detection of intrahepatic lithiasis:...

Sequential scintiphotography with Tc-99m pyridoxylideneglutamate was used to evaluate patients under strong suspicion of intrahepatic stones. The scintiphotos of 19 cases were analyzed. Results indicate that the sequential study reveals an excretion pattern pertinent to the diagnosis of intrahepatic stone. This simple and innocuous approach would be a useful screening technique for this disease.
