Multimodality imaging in a spinal bone metastatic pheochromocytoma/paraganglioma participant with spinal canal involvement. The whole-body fused sagittal (a, b) images of ⁶⁸Ga-DOTA(0)-Tyr(3)-octreotate ([⁶⁸Ga]DOTATATE, a) PET/CT, ¹⁸F-fluoro-2-deoxy-d-glucose ([¹⁸F]FDG, b) PET/CT, and sagittal short tau inversion recovery (STIR, c, d) images of thoracic (c), lumbar (d), and axial (e–j) fused PET/CT images of [⁶⁸Ga]DOTATATE (e–g) and [¹⁸F]FDG (h–j) of a 71-year-old man with negative germline testing in pheochromocytoma and paraganglioma susceptibility genes. This figure shows spinal bone metastases (arrows, a–j) in T11, L3–L4, and sacrum with spinal canal involvement. In such cases, a dedicated MRI of the spine (showing intradural tumors, here) to derive more anatomic information should be obtained
