Comparison of [F]Fluorocholine and [F]Fluordesoxyglucose for assessment of progression, lung metastasis detection and therapy response in murine 4T1 breast tumor model.

The [F]Fluorocholine ([F]FCH) tracer for PET imaging has been proven to be effective for several malignances. However, there are only a few studies related to its breast tumor applicability and they are still limited. The aim of this study was investigate the efficacy of [F]FCH/PET compared to [F]FDG/PET in a murine 4T1 mammary carcinoma model treated and nontreated.
