Biomarker model predicts breast cancer risk without racial bias
By Liz Carey
A new breast cancer risk assessment technique that uses mammography biomarkers shows no racial bias, according to research presented November 29 at the RSNA meeting.

Mammograms contain highly predictive biomarkers of future cancer risk. A deep learning model using screening mammography alone can accurately discriminate patients at risk of developing DCIS and invasive disease across races, work at Massachusetts General Hospital suggests.

DTI-MRI reveals impact of soccer heading on brain
By Amerigo Allegretto
Diffusion tensor imaging (DTI)-MRI reveals declines in the brain microstructure and function caused by soccer heading.
November 28, 2023
Researchers used diffusion tensor imaging, an MRI technique, to study the impact of soccer heading on the brain. This method tracks the microscopic movement of water molecules through brain tissue to characterize the brain's microstructure. Image and caption courtesy of the RSNA.
CT reveals marijuana, cigarette smokers at higher risk of emphysema
By Amerigo Allegretto
Chest CT images reveal that cigarette and marijuana smokers are at higher risk of developing emphysema, according to an RSNA 2023 presentation.
