Abstract
The instant invention provides a method for diagnosing an infection in a subject by administering to the subject a compound suitable for imaging which binds to a thymidine kinase present in the infecting organism, and obtaining an image of the subject to determine the presence and location of the compound, wherein a localization of the compound is indicative that the subject has an infection.
Claims8
A method for monitoring the efficacy of treatment in a subject having a bacterial infection comprising:
- administering to the subject a first dose of a compound suitable for imaging which binds to a bacterial thymidine kinase present in the infecting organism;
- obtaining a first image of the subject to determine the presence and location of the compound;
- administering to the subject a second dose of a compound suitable for imaging which binds to a bacterial thymidine kinase present in the infecting organism at a time subsequent to the first administration;
- and obtaining a second image of the subject to determine the presence and location of the compound wherein the compound is a radiolabeled nucleoside;
- wherein a decrease in amount of compound localized to a particular location is indicative of effective therapy.
