New data suggest that both obesity and Alzheimer's can cause excess grey matter cortical thinning. 

MRI a 'far superior' modality for dense breast imaging

Example of various breast MRI protocol sequences that offer different types of soft tissue enhancement. Imaging performed on a Siemens Magnetom system. Breast MRI can help see through dense breast tissue to better detect cancers. #densebreasts #Breastdensity #BreastMRI

The modality outperformed digital breast tomosynthesis, handheld ultrasound and automated breast ultrasound for cancer detection in a large cohort of women with dense breast tissue.

VIDEO: Cold-cathode X-ray systems may disrupt the medical imaging market

The Nanox ARC cold-cathode, tomosynthesis 3D X-ray system is currently pending FDA clearance. If cleared, it would be the first device of its kind to offer cold-cathode X-ray tube technology and the ability to slice through the anatomy in images similar to CT scans to aid diagnosis. The new type of tube also could greatly reduce the size and weight of X-ray systems. The vendor sees this system as key to its larger plan to address health disparities and access to imaging world-wide. #Nanox

Bhvita Jani, research manager at Signify Research, explains advances in cold-cathode X-ray tube technology and how this might represent a major shift in radiology imaging systems. 
 

CTA-based radiomics can reliably estimate time since stroke onset

Radiomics features could be especially useful for determining TSS in scenarios where clinical data is lacking or unreliable, such as when patients have altered mental status.
