MRI shows less gray matter in kids with sleep apnea March 20, 2017 -- MRI scans have revealed significant reductions of gray matter in several brain regions of children with moderate or severe obstructive sleep apnea, compared with children who sleep normally, according to a paper published online March 17 in Scientific Reports, one of the Nature journals.
Adding DBT to breast screening helps BI-RADS accuracy March 17, 2017 -- More and more clinical evidence indicates that using digital breast tomosynthesis (DBT) for breast cancer screening reduces recall rates and increases the detection of invasive cancers. Now another benefit of the technology is coming to the fore: Adding DBT to digital mammography helps breast imagers categorize lesions more accurately, according to research presented at ECR 2017.
MRI can replace biopsy for prostate cancer surveillance March 17, 2017 -- MRI can be used in place of serial biopsy as part of an active surveillance program for prostate cancer, complementing prostate-specific antigen levels and digital rectal exams in early-stage patients. The combination could help guide who needs treatment without the need for biopsy, according to a study in the March issue of the American Journal of Roentgenology.
