Atherosclerosis a Signal for Brain Drain?

Plaque burden was linked to cognitive impairment in a population-based study.

ADHD: Brain Iron May Be Marker

CHICAGO -- Low Fe levels in the brain may signal the presence of attention-deficit/hyperactivity disorder (ADHD), researchers reported here.

Radiation Safe in Unbiopsied Lung Cancer

CHICAGO -- Treating people with stereotactic body radiation for suspected -- but unbiopsied -- lung cancers appears to allow for acceptable local control of the disease with low toxicity, researchers reported here.

Gastric Artery Embolization Tied to Weight Loss

CHICAGO -- Embolization of the left gastric artery was associated with significant weight loss compared with that seen in patients who underwent a control procedure, researchers found.

Type of Contrast May Mean More Comfortable CT

CHICAGO -- Patients who underwent abdominal or pelvic CT imaging with a low-osmolar contrast agent reported more discomfort during the exam than patients who received an iso-osmolar agent, researchers said here.

Repeat CT Scans May Up Breast Ca Risk in Young Women

CHICAGO -- A female teenager who undergoes multiple chest or cardiac CT studies may see her 10-year risk for breast cancer double, researchers said here.

Climbers Face Lasting Effects if Brain Swells

CHICAGO -- Extreme mountaineers who develop serious brain swelling at altitude appear to have lasting evidence of small hemorrhages in their brains, researchers said here.

'Scatter' Effects of Mammography Pose Little Risk

CHICAGO -- Scatter radiation from screening mammography is minimal, even to the thyroid, and results in negligible risk to the patient, researchers reported here.

RSNA: Growth Hormone May Help Heavy Women With Bone Problems

CHICAGO -- Premenopausal women who are obese may not be spared from osteopenia, as some research has suggested, but growth hormone therapy may help spur bone formation, researchers said here.

RSNA: Radiation May Pose Less Risk in Older Patients

CHICAGO -- In an elderly population, cancer risk from CT scans may be overestimated, researchers said here.

RSNA: Kids' Lead Exposure Linked to Multiple Adult Problems

CHICAGO -- Lead exposure in childhood leads to permanent brain damage and life-long problems with attention and impulsivity control, researchers said here.

RSNA: Radiologists Disagree with USPSTF on Mammography

CHICAGO -- In this exclusive InFocus芒鈥灺� report, leaders of two radiology groups charge that implementing the new breast cancer screening guidelines from the U.S. Preventive Services Task Force (USPSTF) will lead to unnecessary deaths.

RSNA: Kids Still Swallow Soda Tabs

CHICAGO -- Pop-top tabs are supposed to stay on soda cans, but they may still end up in children's stomachs, a researcher said.

RSNA: Unneeded CT Series Add to Radiation Burden

CHICAGO -- More than half of patients who have abdominal computed tomography (CT) scans may be getting extra series of tests that aren't necessary and that lead to increased radiation exposure, researchers said here.

RSNA: Portable CT Scan Saves Time to Save Brain in Stroke Patients

CHICAGO -- Bringing the CT to the stroke patient, rather than the other way round, dramatically reduced door-to-scan time in a community hospital, researchers said here.

RSNA: Dry-Needling Plus Steroid Effective for Plantar Fasciitis

CHICAGO -- For patients with plantar fasciitis, a notoriously difficult condition to treat, an Italian team has come up with a novel approach that uses dry-needling combined with a steroid injection, researchers said here.
