First Claim
Patent Images
1. A method for detecting a cell in a subject comprising:
- a. administering to the subject a cell that is labeled with a fluorocarbon imaging reagent, wherein at least a portion of the fluorocarbon imaging reagent is internalized into the cell; and
b. examining at least a portion of the subject by 19F magnetic resonance imaging, thereby detecting the cell that is labeled with the fluorocarbon imaging reagent in the subject.

Abstract
The disclosure provides, in part, fluorocarbon imaging reagents and formulations for the ex vivo labeling of cells. Labeled cells may be detected in vivo or ex vivo by a nuclear magnetic resonance technique, such as magnetic resonance imaging (MRI) or magnetic resonance spectroscopy (MRS). The disclosure additionally provides methods for using the imaging reagents in a variety of clinical procedures.
