Endorectal-body phased-array coil improves prostate cancer detection

The image quality for detecting prostate cancer is significantly better for MRI at 1.5 T using an endorectal-body phased-array coil as compared with the 3.0 T imaging using the torso phased-array coil, a recent study found.

Computer-aided guidance system simplifies the surgical treatment for movement disorders

Tens of thousands of people who experience movement disorders associated with Parkinson's and a variety of other neurological conditions stand to benefit from a new guidance system that uses computerized brain-mapping techniques to significantly improve an increasingly popular procedure called deep brain stimulation.

Music training may change the brain

New research shows that the special training of music conductors seems to enhance the way their senses work together - enabling them to quickly tell who played a wrong note, for example. Scientists hope the research will lead to new discoveries about how music training may change the brain.

MRI measurements of scar tissue accurately predict the risk of arrhythmia-related sudden death

Using magnetic resonance imaging (MRI) scans of the heart wall, researchers at Johns Hopkins have found that people whose muscle wall thickness contained more than 25 percent scar tissue were approximately nine times more likely to test positive for a fast and dangerous heart rhythm known as ventricular arrhythmia.
