New technology provides clear images of brain with Parkinson's without use of intrusive restraints

A technology being developed at Oak Ridge National Laboratory promises to provide clear images of the brains of children, the elderly and people with Parkinson's and other diseases without the use of uncomfortable or intrusive restraints.

Awake imaging provides motion compensation reconstruction, which removes blur caused by motion, allowing physicians to get a transparent picture of the functioning brain without anesthetics that can mask conditions and alter test results. The use of anesthetics, patient restraints or both is not ideal because they can trigger brain activities that may alter the normal brain functions being studied.

With this new capability, researchers hope to better understand brain development in babies, pre-teens and teen-agers. In addition, they believe the technology will provide unprecedented insight into conditions such as autism, drug addictions, alcoholism, traumatic brain injuries and Alzheimer's disease.

"With this work, we're hoping to establish a new paradigm in noninvasive diagnostic imaging," said Justin Baba, a biomedical engineer who heads the ORNL development team.

The study, which was performed in collaboration with Thomas Jefferson National Accelerator Laboratory and Johns Hopkins University, utilized an awake imaging scanner and awake, unanesthetized, unrestrained mice that had been injected with a radiotracer known as DaTSCAN, provided by GE-Medical.
