Efficacy of 68Ga-Pentixafor PET/MR in Detecting Non-Hodgkin Lymphoma and Multiple Myeloma Lesions

In this study, the investigators intend to utilize 68Ga-Pentixafor Positron Emission Tomography（PET） imaging for patients diagnosed with non-Hodgkin lymphoma (NHL) and multiple myeloma (MM). The investigators will compare the imaging results with those obtained from 18F-FDG imaging, and a correlation analysis will be performed to assess progression-free survival among patients. This analysis aims to evaluate the diagnostic efficacy and the potential for early prediction of treatment efficacy associated with 68Ga-Pentixafor in these specific conditions.
