Thanks to recent research by researchers at the Hebrew University, physicians may soon be able to compare long-term brain scans of the same patient and differentiate between healthy and diseased brain tissue without having to perform an invasive or dangerous procedure. [19659016] Aviv Mezer and his team from the HUJI Brain Sciences Center Edmond and Lily Safra have successfully transformed an MRI (magnetic resonance image) from a diagnostic camera that records images of our organs, bones and nerves into a device that records changes in HUJI's biological makeup can be brain tissue. This new MRI could help physicians diagnose the onset of illness more quickly and begin treatment.

Mezer said that MRI has long been used as a method of analyzing the brain.

"Now that we know how to measure water very efficiently and accurately, we can now see the other aspect: how water interacts with the environment, Mezer explained. "In that sense, we measure the composition of molecules."

He said that this is a new level of information that has hitherto been hidden from the medical community.

Mezer compared this new type of MRI reading with a blood test.

 "When we do a blood test, we see how many white blood cells are in our body, and whether that number is higher for illness than normal," Mezer said.

This new analysis provides such information to the brain.

"We know that there is a big difference in the study of the brain after death in the macromolecules in various diseases – but now we can only see these changes after death," said Mezer. "The hope is that with our new approach, we will be able to recognize these macromolecules in the brain and recognize the onset of neurodegenerative diseases while people are still alive."

In particular, Mezer assumes that the new MRI technique allows for a decisive understanding of how our brain ages. "When scanning the brain of young and old patients, we found that different brain areas get different ages. For example, in some areas of the white matter there is a decrease in tissue volume of the brain while the tissue volume in the gray matter remains constant. However, we have seen major changes in the molecular makeup of gray matter in younger and older volunteers.

The result, he believes, is that patients are more likely to get the correct diagnoses sooner and start treatment sooner, which may help them Maintaining Longer Improved Quality of Life – All Thanks to Non-Invasive Technique.
