Researchers have created a new magnetic metamaterial that can reduce MRI times while improving the resolution of the images

Medical

Magnetic metamaterial amplifies MRI for clearer images in less time

MRI is a great tool for diagnosing disease, but it can be costly and cumbersome. Now, engineers at Boston University have developed a new device, small enough for a patient to wear inside the machine, that could boost the signal and provide higher-resolution images at lower magnetic strengths.

Artificial Intelligence platforms look set to change the face of medical imaging analysis across the UK's National Health Service (NHS

Nvidia’s AI tech set to analyze medical scans for UK’s public health system

Artificial Intelligence promises to revolutionize many fields, but few as important as healthcare. With that in mind, Nvidia and King's College London have teamed up to build and train an AI platform to interpret radiological scans for hospitals across the UK.

Researchers have designed a vest packed with flexible radio coils they say will improve MRI imaging for breast cancer detection

Medical

Researchers developing MRI waistcoat for better breast cancer detection

Researchers in Vienna are making some promising progress in the field of breast cancer detection, developing a new method that revolves around a waistcoat packed with flexible radio frequency coils.

A new study has revealed that one of the key facets of consciousness seems to be complex, long-distance, communication across multiple brain regions

Medical

Neuroscientists close in on the brain signature for consciousness

A new study has scanned the brains of different patients, from healthy individuals to those in vegetative states, and identified four different neural activity patterns that span consciousness to unconsciousness.

An MRI technique could predict the onset of dementia three years before symptoms appeared with an accuracy rate up to 95 percent

Medical

MRI technique predicts dementia up to three years before symptoms appear

A new study suggests an MRI scan can predict whether a person will develop dementia up to three years before any cognitive symptoms are detectable. It's hoped the tool will be able to better identify at-risk patients so preventative measures can be deployed to slow the onset of neurodegeneration.

Researchers have found that a cannabis extract might help relieve symptoms of psychosis

Medical

Cannabis extract could form basis of new anti-psychotic treatments

Marijuana compounds like cannabidiol (CBD) have been found to impart benefits to the brain without the negative “stoned” side-effects. Now, researchers at King’s College London have shown that CBD could help reset the brain abnormalities found in people suffering from psychosis.

A joint collaboration between NYU and Facebook hopes to demonstrate results within the year

Medical

Facebook and NYU turn to AI to make MRI scans up to 10 times faster

The NYU School of Medicine's Department of Radiology is joining forces with Facebook's Artificial Intelligence Research group on a project aiming to utilize AI to dramatically speed up the time it takes to complete a magnetic resonance imaging (MRI) scan.

An Australian study has shed light on the neural basis of alcohol-related aggression

Biology

Brain scans show why people get aggressive after a drink or two

It's common knowledge that a drink or two can lower inhibitions and result in people becoming aggressive and violent. Researchers from the University of New South Wales in Australia are asking why, using MRI scans to trace which part of the brain controls aggression.

Researchers have discovered gadolinium, a chemical regularly given to patients for MRI scans, is accumulating in the eyes and may provide increase understanding of strokes

Medical

Chance discovery reveals eyes could shine light on stroke severity

Gadolinium, a contrast agent used to improve MRI imaging, has been shining a light on brain diseases and damage for years. Now scientists from the NIH believe it could be about to reveal more, with the chance discovery of gadolinium leaking into the eyes of stroke patient MRIs.

A new MRI method can confidently identify if a kidney tumor is malignant or benign without the need for a biopsy

Medical

MRI advance can detect malignant tumors without need for biopsy

Traditionally when a small tumor is discovered in the kidney an invasive biopsy is needed to determine if it is malignant or benign. Researchers have developed a breakthrough new method that uses current MRI technology to accurately identify the aggressiveness of a tumor without a biopsy

3D-printed organs could let surgeons practice and plan dangerous operations

Researchers have used 3D-printing technology to produce individually-tailored model organs. These dummy organs could one day improve your chances of surviving surgery, by allowing doctors to plan and practice a lifesaving procedure on a realistic replica before putting you to the scalpel.

Transmitter chip helps doctors track swallowable electronics through the body

In the future, tiny medical devices could swim through our bodies to diagnose diseases, but keeping track of them all can be tricky. A new invention out of Caltech might make that easier: a chip loaded with sensors that can ping its location in the body, thanks to MRI-inspired technology.
