This is your brain on smartphones: MRI study reveals altered network strength in brains of smartphone 'addicts'

The study, which was published in Brain and Behavior, found that individuals who used their smartphone excessively displayed different strengths in the prefrontal and parietal neural network.

Patient with severe, lung damage from COVID. Images in a 54-year-old man with COVID-19–related acute respiratory distress syndrome and subsequent fibrosis. (A) Axial CT 2 weeks after admission shows diffuse ground-glass opacity (GGO) with reticular abnormality and traction bronchiectasis in right middle lobe, indicating organizing phase of lung injury. (B) Axial CT 6 months after admission shows decreased GGO but extensive traction bronchiectasis and architectural distortion, suggesting fibrosis. RSNA

Lung scarring occurs in up to 11% of patients recovered from COVID, regardless of infection severity

Researchers cannot yet determine whether these changes will progress or resolve in the long term.

Seaweed molecules could lead to big improvements for heart surgery patients

“There is a crucial need to develop synthetic vascular graft materials that will increase the rate of long-term functions,” one researcher said. Could materials derived from seaweed help fill that need?

Examples of breast imaging. What does breast imaging look like? What does breast cancer look like? What do radiologists look for on mammograms?

New findings ‘challenge the use of imaging surveillance’ after any mastectomy

Regardless of whether or not they received reconstructive surgery, post-mastectomy patients probably need no follow-up imaging for breast cancer.

Philips MRI

Amid looming helium shortage, Philips enters research agreement to study alternative cooling methods for MRI scanners

The healthcare industry accounts for close to 30% of global helium consumption, with MRI equipment needs accounting for a significant portion of that figure.

Radiology journal showcases top medical images of 2022

Capping the RSNA 2022 conference in Chicago, an RSNA editorial board has selected a 3D cinematic rendering as the single best radiological image of the year.

AI generates imitation lung X-rays replete with diagnosable pathologies

Stanford researchers have created synthetic yet highly realistic chest X-rays by customizing an open-source AI model called Stable Diffusion for rendering text as images.
