[Hepatic scintigraphy using 123I-rose bengal].

The paper is devoted to the experience in diagnostic investigations using rose bengal, labeled with half-life 123I (123I-RB). The drug was synthesized in the B. P. Konstantinov Leningrad Institute of Nuclear Physics, USSR Academy of Sciences. Analysis of the results of investigations of 201 patients with diseases of the liver and biliary tracts revealed the advantages of 123I-RB over standard RPs of similar diagnostic purpose. Owing to low radiation exposure one could use higher activity (up to 120 MBq and more) of the drug. It made it possible to combine a study of the functional parameters of the hepatobiliary system and obtaining scintigraphic data on the structure of the liver and biliary tracts. 123I-RB is the best radiodiagnostic agent for a study of function and topography of the liver in patients with an increased blood level of bilirubin.
