Fluorine-19 MRI signal phenotype in solid tumor following in situ perfluorocarbon cell labeling
✦AI Summary
Researchers have validated the use of fluorine-19 MRI and perfluorocarbon nanoemulsions to track myeloid-lineage immune cells in tumors. This noninvasive imaging technique allows for the quantification of tumor-associated macrophages, which are linked to cancer progression and immunotherapy resistance.
Why it matters
This provides a new, noninvasive biomarker for monitoring tumor microenvironments, potentially improving the efficacy of cancer immunotherapies.
