Scientists have recently increased the resolution of magnetic resonance imaging (MRI) by a factor of 64 million. They used this

The technology will help doctors find changes in the human brain that occur due to neurodegenerative diseases such as Alzheimer's disease, as well as normal aging. The mouse brain scan was published as part of a new paper published in the journal PNAS.
“This will really help.We can begin to look at neurodegenerative diseases in a completely different way,” said J. Allan Johnson, lead author of the study and professor of radiology at Duke University.

For 40 years, a scientist with the helpAn ever-changing group of students and researchers at Duke University's Center for In Vivo Microscopy have been working to improve MRI, which was invented by American physician Dr. Raymond Damadian 50 years ago.
To improve it, scientists createdan advanced MRI equipped with a powerful 9.4 Tesla magnet. By comparison, most MRIs have a 1.5 to 3 Tesla magnet. They also added gradient coils that are 100 times more powerful than existing models and create images. They also used a high-speed computer, which, according to the statement, has the capacity of approximately 800 laptops.
