MRI scan lasting FOUR DAYS has produced the 'most detailed scan of the human brain ever' and could be a window into coma and depression Researchers needed to use the brain of a dead person to get the images Usual MRI scans take no more than 90 minutes - but this took 100 hours The scanner is far more powerful and would be able to show tiny changes Research like this will lead to a better understanding of brain abnormalities

An MRI scan that lasted four days has produced images of the brain that are more detailed than ever before.

The findings show tiny changes inside the brain and scientists say they could be a window into conditions such as depression or coma. 

It was only possible by using the brain of someone who had died, because a live person couldn't tolerate the days-long scan and the images would have been too blurred by blood flow and movement.

The scanner was also far more powerful than those in hospitals, producing images so detailed that it 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.

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 result has 'the potential to advance understanding of human brain anatomy in health and disease,' the researchers claim.

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 began, researchers built a custom case that held the brain still and allowed it to withstand the constant magnetic waves. 

Parts of the brain can be seen in vivid detail, including the amygalda, a collection of nuclei no bigger than an almond, nestled deep within the brain.

Conditions such as anxiety, autism, depression, post-traumatic stress disorder, and phobias are suspected of being linked to abnormal functioning of the amygdala due to damage or a chemical imbalance. 

The cerebellum, which controls voluntary movement in the body, is also strikingly clear.  

It wouldn't have been possible to get these results without the strong MRI scanner, which had a magnet strength of seven Tesla – hospital ones are usually three Tesla.

Or, if the brain had been that of a living person - any movement during a scan can ruin the
