Differences in lesion detection in a metastatic prostate cancer patient using 99mTc-MDP (bone scan) showed lesions in the ribs and vertebrae A), 18F-FDG PET scan displayed uptake in the femur and in the vertebrae B), and 89Zr-IAB2M imaging identified more true-positive lesions than 99mTc-MDP and 18F-FDG C). Optimization of pharmacokinetics. A comparison of serum clearance D) and lesion uptake E) between 89Zr-IAB2M (minibody) and 89Zr-J591 (full length mAb cognate) over time.
