  • Methods and compositions for plasma and organ imaging
    Patent number: 4606908
    Abstract: Halogenated dibenzazepines, particularly flouro- or iododesmethylimipramine, find use for measuring regional blood flows and for retention in particular organs for radioactive imaging. Such compositions are introduced into the arterial flow leading to the organ, and the compositions bind to the organ as a result of interaction with cellular receptors. The compositions have been found to display very high retention rates in the organ for relatively long periods of time.

  • Radiolabeled neoglycopeptides
    Patent number: 4401647
    Abstract: Radiopharmaceuticals and method are provided for scintigraphic evaluation of the liver. The radiopharmaceuticals comprise a radionuclide (technetium) labeled neoglycoprotein which provides for specific binding of the radiopharmaceutical to hepatocytes and allows for accurate determination of rates of binding and release of Tc-99m to and from the liver. The observed rates may then be used to determine diseased states, conveniently using an appropriate algorithm for the calculation.
