Could brain imaging predict future behavior?
By Wayne Forrest
It may sound like something out of the technothriller "Minority Report," but could medical imaging modalities such as functional MRI someday be used to predict future behavior, such as someone's propensity to commit a crime? Maybe, but discoveries so far have fallen short of realizing imaging's potential in this regard, according to an article published January 7 in Neuron.

CAD for virtual monochromatic CTC images shows high accuracy
By Eric Barnes
A computer-aided detection (CAD) algorithm analyzed virtual monochromatic dual-energy CT colonography (CTC) images accurately with few false positives in a study from Massachusetts General Hospital. The researchers believe the study could pave the way to more accurate minimal-prep CTC.

AJR: CT shows evidence of lung cancer spread via airways
By Eric Barnes
New research with CT supports the hypothesis that lung adenocarcinoma may spread through the airways and not just through the blood. So-called aerogenous metastasis of lung cancer has implications for staging, management, and prognosis and may be underrecognized, the authors report in the American Journal of Roentgenology.

Radiation alarm Bleeper Sv reduces dose to cardiac cath staff
By Brian Casey
A beeping radiation dose monitor that is worn by healthcare personnel during cardiac catheterization procedures successfully reduced dose in a trial conducted by Texas researchers. Called Bleeper Sv, the monitor emits a warning sound that becomes louder and more frequent as exposure to radiation grows -- giving personnel a chance to modify their work habits to reduce dose.
