Only one-third of patients received osteoporosis medication after vertebral augmentation. The incidence of new vertebral fractures fell from 0.519 to 0.076 per person-year after starting medical management (incidence rate ratio 6.79, 95% CI 3.37-15.51), a 6-fold decreased risk.
Percutaneous MWA of T1 RCC showed 76% 10-year overall survival, 85% cancer-specific survival, and 83% local progression-free survival, with stable renal function and low complications.
Integrated model combining emphysema, Pi10, airway branch count, and clinical data detected undiagnosed COPD with AUC 0.83 (95% CI 0.80-0.86) in 5,014 lung screening participants, up from 0.69 for emphysema alone, reducing confirmatory spirometry referrals from 41% to 34%.
FAPI PET/CT showed 93.0% sensitivity vs 76.5% for FDG (p=0.002) in 176 patients with suspected HPB cancers. Nodal accuracy was 86.8% vs 71.1%. Dual-tracer approach did not improve accuracy. Prospective validation needed.
