Powerful MRI technology can be scanned continuously for up to 100 hours

With the support of powerful magnetic resonance imaging (MRI) technology, after more than 100 hours of scanning, U.S. researchers have obtained the most detailed three-dimensional image of the human brain to date, with a resolution large enough to show objects less than 0.1 mm in diameter, promising to improve understanding of health and the structure of the brain, Science News reported.to obtain the new image, researchers at Massachusetts General Hospital in Boston and elsewhere studied the brains of a 58-year-old woman who died of viral pneumonia. The woman's donated brain is thought to be healthy and has been preserved for nearly three years.before the scan began, the researchers customized a spherical polyurethane container that would keep the brain to be scanned stationary and interfere with the escape of bubbles. The brain was then loaded into a powerful MRI machine called the 7T and scanned for nearly five days.7T is powerful, scans are long enough, and the brain is highly stationary, which makes the resulting image extremely high resolution.researchers explained that scanning the brains of living people would not result in images with such high resolution. First of all, living people cannot withstand scans that last 100 hours. In addition, even very small movements, such as breathing and blood flow, can cause blurry images.scans, which show vivid details of brain structures such as almonds, may provide a deeper understanding of the relationship between subtle changes in brain structure and diseases such as post-traumatic stress disorder.researchers have been trying to identify brain abnormalities linked to mental illnesses such as coma and depression, and these detailed brain images provide clues. They said the images "are expected to improve understanding of health and the structure of the brains of sick people."'ve never seen a complete brain like this," said Priti Barchandani, an electrical engineer at the Mount Sinai Icahn School of Medicine in New York City who was not involved in the study. This is absolutely unprecedented. "(Science and Technology Daily)
