MRI scanning lasting FOUR DAYS has produced the 'most detailed scan of the human brain ever' and could be a window into coma and depression
- Usual MRI scans take less than 90 minutes – but this took 100 hours
- The scanner is far more powerful and would be able to show tiny changes
- This research will lead to a better understanding of brain abnormalities
An MRI scan that has lasted four days has produced images of the brain that are more detailed than ever before. brain and scientists say they could be a window in conditions like depression or coma.
It was only possible by using the brain of someone who had died, because a live person could not tolerate the days-long scan and the images would have been too blurred by blood flow and movement. also far more powerful than those in hospitals, producing images so detailed that they could see things smaller than 0.1mm.
Scientists said they have never seen anything like it and hope it paves the way for more research into the brain's health.

Parts of the brain can be seen in vivid detail, including the cerebellum
The images, created by researchers at Massachusetts General Hospital in Boston, took more than 100 hours – far more than the usual 15 to 90 minute scan
The brain belonged to a 58-year-old woman who had died three years ago of pneumonia and had no neurological damage.
Before the scan started, researchers built a custom case that held the brain still and allowed it to withstand the constant magnetic waves.
Parts such as anxiety, autism, depression, post-traumatic stress
Parts of the brain can be seen in vivid detail, including amygalda, a collection of nuclei no larger than an almond, disorder, and phobias are suspected of being linked to abnormal functioning of the amygdala due to damage or chemical imbalance.
The cerebellum, which controls voluntary movement in the body, is also strikingly clear.
It would not have been possible to get these results without the strong MRI scanner, which had a magnet strength of seven Tesla – the hospital ones are usually three Tesla
Or, if the brain had been that of a living
MRI scans are already used to detect a variety of brain conditions such as tumors, swelling, or developmental problems.
But no one would be able to withstand hours and days of remaining so still.
'We have not seen a whole brain like this,' Professor Priti Balchandani of the Icahn School of Medicine at Mount Sinai in New York City, who was not involved in the study, said, according to Science News.
'It's definitely unprecedented.'
Using postmortem samples along with developing technology 'gives us an idea of what's possible,' Professor Balchandani said.
The images push boundaries and could hold clues for researchers trying to pinpoint hard-to-see brain abnormalities involved in disorders such as comas and psychiatric conditions.
The FDA in the US first approved the 7T scanner for clinical imaging in 2017 and was installed in Glagow's Queen Elizabeth University Hospital (QEUH) in 2016, at a cost of £ 10million. research and diagnosis and a variety of conditions such as stroke, vascular dementia, Alzheimer's disease and epilepsy.
Magnetic Resonance Imaging (MRI)
Magnetic resonance imaging (MRI) is a type of scan that utilizes strong magnetic fields and radio waves to produce detailed images of the inside of the body
An MRI scanner is a large tube that contains powerful magnets.
An MRI scan can be used to examine almost any part of the body, including the brain and spinal cord, the bones and joints, the breasts, the heart and the blood vessels and internal organs – such as the liver, womb or prostate gland.

The results of an MRI scan can be used to help diagnose conditions, plan treatments, and evaluate how effective previous treatment has been
. , which consists of hydrogen and oxygen atoms. At the center of each hydrogen atom is an even smaller particle, called a proton. Protons are like tiny magnets and are very sensitive to magnetic fields
When you lie under the powerful scanner magnets, the protons in your body line up in the same direction, in the same way that a magnet can pull the needle of a compass
Short bursts of radio waves are then sent to certain areas of the body, knocking the protons out of alignment. When the radio waves are turned off, the protons are realigned. This sends out radio signals, which are picked up by receivers.
These signals provide information about the exact location of the protons in the body. They also help to distinguish between different types of tissue in the body, because protons in different types of tissues are different at different speeds and produce distinct signals
In the same way that millions of pixels on a computer screen can create complex pictures, the signals from the millions of protons in the body are combined to create a detailed image of the inside of the body
