1. A method for assessing the labeling of cells intended for administration to a patient, the method comprising:
- a) contacting cells of a plurality of substantially identical cell samples with an in vivo imaging reagent;
b) detecting the in vivo imaging reagent in the samples; and
c) assessing the labeling of the cells with the in vivo imaging reagent.

Abstract
The disclosure relates to methods for labeling cells ex vivo with agents that can be detected by MRI or PET techniques, or other techniques that permit non-invasive imaging of living organisms. The labeled cells can be re-administered to the patient and the movements of the labeled cells can be tracked in vivo by MRI, PET or other techniques. In part, the disclosed methods involve labeling a series of cell samples ex vivo determining the association of label with the cells, such that an appropriate dosage of labeled cells can be determined for each patient.
