Detection of Bone Metastases by ⁶⁸Ga-DOTA-SSAs and ¹⁸F-FDG PET/CT: A Two-Center Head-to-Head Study of Gastroenteropancreatic Neuroendocrine Neoplasms

Figure 4

Dual-tracer imaging in a 57-year-old man with rectal NET G2 (Ki-67 index 3%), accompanied by liver, lymph node, and bone metastases. The patient suffered from systemic diffuse bone metastases, including in the spine, pelvis, ribs, sternum-clavicle-scapula, proximal limbs, and skull. Computed tomography findings mainly manifested osteogenesis changes. b1 and c1 show more bone lesions than ¹⁸F-FDG PET/CT imaging. (a–c) Maximum intensity projection, osteogenesis in the pelvis, and osteogenesis in the spine, respectively, detected by dual-tracer imaging.
