Image: AI-generated maps of local brain aging; cooler colors indicate brain regions that appear younger relative to chronological age, whereas warmer colors indicate regions that appear older. Compared with cognitively normal adults (left), people with cognitive impairment (right) show substantially more widespread patterns of advanced local brain aging, particularly in frontal and temporal brain regions.

Images from a 59-year-old man admitted to intensive care unit with fever and back pain after prior intestinal surgical procedure. Despite intravenous meropenem, fever persisted. White blood cell and CRP levels were high. (A) Maximum-intensity-projection PET images showed increased uptake in column corresponding to the sixth and seventh thoracic vertebrae. Subsequent sagittal (B), axial (C), and coronal (D) PET/CT images confirmed increased 18F-FDG uptake in intervertebral disk and adjacent vertebrae in which spondylodiskitis was suspected. (Domenico Albano et al., Journal of Nuclear Medicine June 2026, 67 (6) 988-994; DOI: https://doi.org/10.2967/jnumed.125.271525)
