Chemokine receptor CXCR4 was expressed in T cells and CXCR4-targeting molecular imaging-
68Ga-Pentixafor PET/CT could be a promising technique to evaluate the extent of thymoma with
higher accuracy. This prospective study is going to investigate whether metabolic
characterization by 68Ga-Pentixafor PET/CT may be superior for diagnosis, distinguish
evaluation for thymoma.
