Pre-therapeutic [⁶⁸Ga]Pentixafor-PET/MRI and [¹⁸F]FDG-PET/MRI of a 52-year-old male MCL patient. Several infradiaphragmatic nodal lymphoma manifestations (blue arrowheads) that show strong [⁶⁸Ga]Pentixafor uptake on PET (top) and fused color-coded PET/MRI (bottom) show only moderate-to-low [¹⁸F]FDG uptake that does not, or only slightly, exceed the [¹⁸F]FDG uptake of the liver. Consequently, measured tumor-to-background ratios (TBR_blood, TBR_liver) are higher for [⁶⁸Ga]Pentixafor-PET than for [¹⁸F]FDG-PET.
