Brains respond differently to thirst depending upon age

Twelve healthy subjects in their 60s and 70s showed a different pattern of brain activations during thirst and satiation than did 10 healthy subjects in their 20s who drank the same amounts and underwent imaging with positron-emission tomography (PET).

Potential blood test to detect lung cancer

A test for four blood proteins may provide a less-invasive follow-up for patients who have suspicious lesions on chest radiographs or computerized tomography (CT) scans, according to a new study led by Duke University Medical Center researchers.

Gastric bypass complications

Obese patients who suffer complications after gastric bypass surgery may face further health risks because their weight exceeds the limits of diagnostic imaging equipment, according to a study presented at the annual meeting of the Radiological Society of North America (RSNA).

Computed tomography angiography accurate in detecting coronary artery disease

Computed tomography (CT) angiography is as accurate as an invasive angiogram in detecting coronary artery disease, according to the findings of the first two prospective multicenter 64-slice scanner trials presented today at the annual meeting of the Radiological Society of North America (RSNA).
