Visualization of skeletal myeloma by 89Zr-DFO-daratumumab immunoPET in an 80 year-old male with osseous myeloma. (A) MIP image from a 89Zr-DFO-daratumumab PET/CT demonstrates multiple foci of osseous avidity, including a left scapular focus (arrow). (B) Axial CT (C) and fused PET/CT images from the 89Zr-DFO-daratumumab PET/CT demonstrate the left scapular focus localizes to a lytic osseous lesion on CT (arrows). (D) MIP image from an 18F-FDG PET/CT 1 week prior fails to identify the lesions seen on 89Zr-DFO-daratumumab PET/CT.
