Figure 5 Example of tumor uptake on 89Zr-rituximab-PET, concordant with CD20 expression in biopsy. Axial images: from left to right attenuation corrected PET, low dose CT and fused PET/CT image of patient 3.
A) 89Zr-rituximab-PET shows intense tumor uptake concordant with a CD20-positive biopsy (inguinal lymph node).
B) Corresponding tumor location on 18F-FDG-PET.
Figure 6 Tumor uptake on 89Zr-rituximab-PET, discordant with CD20 expression in biopsy. Axial images: from left to right attenuation corrected PET, low dose CT and fused PET/CT image of patient 6.
A) 89Zr-rituximab-PET shows tumor uptake discordant with a CD20-negative biopsy (axillar lymph node). B) Corresponding tumor location on 18F-FDG-PET.
