Originating from neural crest–derived sympathetic nervous system cells, neuroblastoma demonstrates remarkable biological heterogeneity, ranging from spontaneous regression to highly aggressive metastatic disease. Accurate imaging is fundamental to diagnosis, staging, risk stratification, treatment planning, response assessment, and surveillance. Over the past four decades, molecular imaging of neuroblastoma has evolved substantially, progressing from conventional metaiodobenzylguanidine (MIBG) scintigraphy to advanced positron emission tomography/computed tomography (PET/CT) tracers that provide complementary biological and molecular information. This review explores the evolution of neuroblastoma imaging, highlighting the strengths, limitations, and emerging roles of established and novel radiopharmaceuticals. 131/123I–MIBG scintigraphy remains the cornerstone of functional imaging in neuroblastoma because of its high specificity for tumors expressing the norepinephrine transporter. MIBG imaging has become integral to the International Neuroblastoma Risk Group (INRG) staging system and is widely utilized for evaluating primary tumors, metastatic disease, and therapeutic response. Furthermore, MIBG serves as a theranostic agent, enabling targeted radionuclide therapy with 131I–MIBG in patients with relapsed or refractory disease. However, approximately 5–10% of neuroblastomas demonstrate absent or low MIBG avidity, limiting its diagnostic utility. Additionally, MIBG imaging is constrained by lower spatial resolution, prolonged imaging protocols, and reduced sensitivity for small lesions compared with modern PET techniques. The increasing availability of PET/CT has led to the development of several promising tracers that address these limitations. 18F–fluorodeoxyglucose (18F–FDG) PET/CT has emerged as an important alternative, particularly in MIBG–negative tumors, dedifferentiated disease, and high–risk neuroblastoma. FDG uptake often correlates with tumor aggressiveness and adverse biological features, providing valuable prognostic information. Beyond FDG, tracers targeting specific aspects of neuroblastoma biology have demonstrated significant potential. 18F–fluorodihydroxyphenylalanine (18F FDOPA) PET/CT exploits catecholamine biosynthesis pathways and has shown superior sensitivity for detecting both primary and metastatic lesions. Somatostatin receptor imaging with 68Ga–DOTA–peptides offers opportunities for patient selection for peptide receptor radionuclide therapy.As novel theranostic paradigms emerge, molecular imaging is increasingly serving not only as a diagnostic tool but also as a means of guiding targeted therapies and monitoring treatment efficacy.

Fibroblast activation protein (FAP) is expressed by cancer-associated fibroblasts and by tumor cells themselves in several sarcoma subtypes, while demonstrating limited expression in normal adult tissues. This biological profile has supported the development of radiolabeled FAP inhibitors, which provide high tumor-to-background contrast on PET imaging and enable theranostic applications with FAP-targeting radioligands. In sarcoma, available studies demonstrate higher FAPI uptake and improved lesion detection compared with [<sup>18</sup>F]FDG PET across most histological subtypes, with particularly notable advantages in low- and intermediate-grade tumors. However, FAPI uptake varies according to histological subtype. In metastatic bone disease, FAPI PET detects more lesions than [<sup>18</sup>F]FDG PET, particularly osteolytic and marrow-based metastases. The benefit is greatest in tumor entities with low [<sup>18</sup>F]FDG uptake, though at the cost of reduced specificity, as benign skeletal and fibroinflammatory processes also take up the tracer. As FAPI and [<sup>18</sup>F]FDG reflect different tumor biology with distinct strengths, their roles are increasingly regarded as complementary rather than competing. Beyond imaging, FAPI PET facilitates patient selection for FAP-targeted radioligand therapy, with early clinical experience demonstrating feasibility and encouraging preliminary evidence of disease control.
