Brain Injury Detection Magnetoencephalography Diffusion Tensor Imaging Sunday, Nov 30 2008 

Mild traumatic brain injury impacts the lives of nearly 1.4 million americans each and every year. This is an astoundingly high number. Nearly 20% of soldiers also may suffer from mild traumatic brain injury.

A new article has come out in the USA Today that talks about brain injuries and their detection. It says that mild brain injuries are now easier for doctors to actually detect. Previously some forms of mild damage may have gone unnoticed even with a brain scan. The article talks about research that was presented at the society for Neuroscience annual meeting.

The researchers are now able to combine a variety of advanced brain imaging techniques. These include magnetoencephalography (MEG) and diffusion tensor imaging (DTI). Using these techniques researchers were able to detect some forms of conventional brain injuries that CT or MRI scans had previously missed. These types of scans are more sensitive in detecting very subtle injuries. The USA today story can be found here.


Detecting Alzheimer’s with MRI Scans Monday, Jul 28 2008 

Researchers have recently used brain scanning technology to capture brain lesions associated with alzheimer’s disease in animal model.  Apparently using the MRI scans, researchers were able to visualize distinct signal voids.  These voids are basically black spots that are located in a number of brain areas including the hippocampus.  The hippocampus is a brain area that is critical for the normal functioning of a person’s memory.  So this is the first time that researchers were able to visualize alzheimer’s disease by brain scans in an animal model.

Eventually this may mean that doctors will be able to detect alzheimer’s disease early on in humans.

“As we search for ways to identify Alzheimer’s early, these MRI studies show that researchers are moving closer to accurate early detection of the disease, and that we may soon be able to use this technology to determine who is at greater risk,” Thies added.

Detection of the disease process this early might allow for more preventative measures to be undertaken. Eventually new alzhiemer’s drugs may be able to slow the disease process.
