PET images of 3 × 3 cubic-well plate containing 89Zr-labeled Jurkat cells suspended in Geltrex™ matrix in a 1-cm3 cube acquired using PET/CT and PET/MRI together with their a corresponding co-registered CT image and b in greyscale. Cell numbers and specific activities per well (kBq/106 cells; indicated in parenthesis) were as follows: L1: 1.07 × 106 (0.67). L2: 1.50 × 105 (0.42). L3: 6.70 × 104 (0.14). M1: 8.20 × 105 (7.23). M2: 3.25 × 104 (15.41). M3: 3.61 × 104 (6.61). H1: 3.99 × 105 (30.63). H2: 1.21 × 105 (8.47). H3: 6.20 × 104 (6.60)
