What would a world without molybdenum-99 (Mo-99) look like? That's a question U.S. nuclear medicine physicians are contemplating as limited Mo-99 supplies decay by half every 66 hours.

Review charts path toward standardized chest x-ray optimization

A 29-study review found no consensus on optimal beam quality for adult chest radiography, prompting calls for standardized research and safer, more consistent protocols.

Fairness-aware training improves pneumonia AI performance across sexes

Low-quality axial T2-weighted MRI scans with gradient-weighted class activation mapping. The low-quality MRI scans (top row) show blurred structures and artifacts making zonal and capsule boundaries indistinguishable. On the same scans with gradient-weighted class activation map overlays (bottom row), red indicates regions that were most heavily weighted by the deep learning model toward the low-quality prediction.

AI framework could improve MRI quality control in prostate cancer

$Artificial intelligence (AI) assistance facilitates correct fracture identification in cases initially missed by human readers. A representative case is shown using anteroposterior radiographs in a 29-year-old male patient with wrist trauma (suspected nondisplaced transverse scaphoid fracture). The reader’s initial unaided assessment (top) resulted in a missed fracture, whereas with AI assistance (bottom), the fracture was correctly identified. The green box represents the fracture location as predicted by the AI tool, the blue box represents the reference standard annotation, and the red dots represent individual reader annotations.$
