Diffusion-Weighted MRI in Breast Cancer: A Practical Review of Techniques and Applications

For breast MRI, diffusion-weighted imaging (DWI) boosts diagnostic AUC to 0.960 when combined with other sequences, and non-contrast DWI screening yields a 99.5% negative predictive value. Malignant lesions show restricted diffusion (low ADC).

EUS vs MRCP Carbon Footprint: EUS 4.2 Times Lower for Bile Duct Stone Evaluation

For intermediate-likelihood choledocholithiasis, EUS generates 4.53 kg CO2e per procedure vs 18.90 kg for MRCP—a 4.2-fold difference. Choosing EUS for 108 patients saved 1,552 kg CO2e (74 trees' annual carbon uptake).

UK Biobank study links obesity to lower renal corticomedullary T1 differentiation

In 4214 UK Biobank adults, higher obesity (body roundness index) was associated with reduced renal corticomedullary T1 differentiation (ΔT1; β = -8.507, 95% CI -11.893 to -5.120), mainly from lower medullary T1, while age correlated with higher cortical T1.

Longitudinal dark-field CT tracks lung microstructure changes over 12 weeks in mouse disease models

Longitudinal dark-field CT in mice revealed microstructural lung changes earlier than attenuation, with distinct trajectories in COPD and injury models, while attenuation remained stable. May serve as early biomarker.

Enlarged basal ganglia perivascular spaces linked to sustained amyloid-β accumulation in Alzheimer's disease

Higher basal ganglia perivascular space burden on MRI was associated with sustained amyloid-β accumulation on follow-up PET in 524 ADNI participants (β=8.350, P=0.001). White matter PVS showed no link. Findings suggest BG-EPVS as a biomarker for amyloid trajectory.
