PET images of 6-well plates containing 89Zr-labeled Jurkat cells acquired using PET/CT and PET/MRI together with their corresponding co-registered CT image. Cell numbers and specific activities per well (kBq/106 cells; indicated parenthetically) were as follows: (A1) 1.36 × 106 cells (2.70). (A2) 5.20 × 105 cells (2.18). (A3) 1.45 × 105 cells (1.57). (B1) 3.83 × 105 cells (31.91). (B2) 6.75 × 104 cells (27.77). (B3) 1.00 × 104 cells (18.37). (C1) 8.45 × 105 cells (7.83). (C2) 1.65 × 105 cells (3.57). (C3) 6.10 × 104 cells (6.93)
