PET/MRI and PET/CT images of the Jaszczak water-filled phantom with a 24.8-mm fillable sphere, filled with 1147.0 MBq of 90Y-chloride. In the first row, there are PET images, in the second row MRI and CT images, respectively, and in the third row fused PET/MRI and PET/CT images, respectively. The results of the phantom study showed that these two systems are very closely calibrated for 90Y, i.e., less than 1% difference
