Nonsolid lung nodules carry greater cancer risk in women
November 24, 2015 -- For lung nodules detected on CT, certain types can pose a higher risk of cancer for women than men, according to a study to be presented at the upcoming RSNA 2015 meeting in Chicago. The results indicate that radiologists may want to consider gender when interpreting CT lung screening scans.  Discuss
3D MRI uncovers risk of stroke in asymptomatic diabetics
November 24, 2015 -- 3D MRI has found evidence of intraplaque hemorrhage among diabetics who have no signs of atherosclerotic disease -- a finding that could greatly increase their risk of an adverse vascular event, according to a study scheduled for presentation at RSNA 2015 in Chicago.  Discuss
MRI finds obesity trigger in obese kids

Tomo-CAD combo targets lung cancer screening
November 23, 2015 -- What if you had a lung cancer screening modality that was better than x-ray and nearly as good as CT, but with less radiation and expense? Researchers from Hungary are investigating the idea with a digital tomosynthesis system that they assembled themselves, along with homegrown computer-aided detection (CAD) software.  Discuss
7T MRI with glutamate uncovers epileptic seizure sites
November 23, 2015 -- Researchers from the University of Pennsylvania are reporting early success with a novel imaging technique that uses 7-tesla MRI and the amino acid glutamate as a biomarker to locate epileptic lesions in the brain that conventional MRI and other modalities may miss.  Discuss
