MRI scoring system could predict liver transplant need
European researchers have developed a functional liver imaging score that uses gadoxetic acid-enhanced MRI to help predict which patients with advanced chronic liver disease might need a transplant or are at greater risk of mortality, according to a study published online November 19 in Radiology.

fMRI shows how brains rebound from hemispherectomy
A new study published online November 19 in Cell Reports sheds new light on how some people are able to recover from hemispherectomy -- removal of half their brain -- and still function at a high level. Functional MRI (fMRI) demonstrated how the brain compensates by restoring communication in certain areas to compensate for the loss.

PET uncovers heightened ischemia after TBI
A novel PET imaging technique has uncovered high levels of ischemia in patients within the first 24 hours after a traumatic brain injury (TBI), but it also showed the condition does begin to subside over the next 10 days, according to a study published online November 11 in JAMA Neurology.

7T MRI finds promising MS biomarker
Using 7-tesla MRI scans, researchers have identified a potentially valuable biomarker of brain inflammation in patients with multiple sclerosis (MS) that could shed light on how the disease progresses, according to a study published online November 12 in the Multiple Sclerosis Journal.

Road to RSNA 2019: Digital Radiography Preview
Digital radiography (DR) maintains its solid foundation of diagnostic support for imaging centers, emergency departments, outpatient clinics, and mobile operations worldwide. Presentations at RSNA 2019 will feature hot topics such as how DR will benefit from artificial intelligence, dark-field x-ray, hardware improvements in DR systems, and other key research findings.
