CT–MRI fusion improved contrast-free lung perfusion mapping for radiotherapy planning
Multimodal CT–MRI perfusion maps matched SPECT better than single-modality methods and reduced high-function lung dose in exploratory planning.

The standardized workflow generated clinically comparable interstitial brachytherapy plans in a median of 10 minutes versus 28 minutes for manual planning.
Two-year local control reached 88%, but median progression-free survival was 5.8 months and systemic treatment changed after 4.4 months.
COMPPARE enrolled 2,524 patients from 51 institutions in 52 months, with Black participation reaching 16% of the cohort.
Poor sleep affected 69% of survivors, while 21.4% screened as high risk for obstructive sleep apnoea.
Seventy-three percent of failures after nonadherent sacral contouring involved sectors that guidelines recommended including in the clinical target volume.
Experts propose selecting radiotherapy–drug regimens using efficacy, scheduling, late toxicity, biomarkers, and patient-reported outcomes rather than maximum tolerated dose alone.
COMPPARE enrolled 2,524 patients from 51 institutions in 52 months, with Black participation reaching 16% of the cohort.
Adaptation would have improved organ sparing or target coverage in 46% of fractions, with a median workflow time of 61.9 minutes.
Different carbon-ion RBE models can assign substantially different biological doses to the same absorbed-dose distribution, requiring context-specific translation.
A 1 mm symmetric MLC closing reduced minimum GTV dose by 25%, while translations caused cumulative target undercoverage.
A 1 cm high-density bolus overcame 6 MV photon build-up, but a 2 cm air gap reduced small-field skin dose by 21%.
TLD-100 over-responded below 7 Gy/s and under-responded above 300 Gy/s, despite remaining dose-independent from 3 to 18 Gy.
A dual-input MRI–CT model segmented 25 neurological organs with a median Dice score of 0.80 and surface Dice of 0.84.
Pelvic insufficiency fractures occurred in 29.2% of patients, with postmenopause and elevated baseline t-PINP independently predicting risk.
