Dynamic Brain Imaging With AI
2022 02 Aug
MRI, electroencephalography and magnetoencephalography are commonly used to study brain activity. However, new research from Carnegie Mellon University introduces a novel, AI-based dynamic brain imaging technology that maps out rapidly changing electrical activity in the brain with high speed, high resolution, and low cost. The research aims to improve... Read more
Deep Learning Reduces Need for Gadolinium Contrast
2021 26 Oct
Gadolinium-based contrast agents (GBCAs), used during MRI scans, enhance brain tissue contrast. GBCAs are crucial for brain tumour care because they highlight areas with abnormal blood-brain barrier permeability that tumours cause. This permits monitoring of treatment response and also guide surgical tumour removal. Disadvantages to using GBCAs include... Read more

Mental health has become a global pandemic. The World Health Organization (WHO) reports one out of four people will suffer from mental disorder in their lifetime. Breaking new ground as is customary for ECR , this year special attention was given to the need for brain imaging in psychiatry . Prof. Jean-Pierre Pruvo head of the... Read more
#RSNA18: MRI finds depression and anxiety brain pattern
2018 27 Nov
In a study presented at the annual meeting of the Radiological Society of North America (RSNA) in Chicago, researchers have uncovered a common pattern of structural similarities and differences in the brains of people suffering from depression and social anxiety using MRI. The study compared major depressive disorder (MDD) and social anxiety... Read more
Scientists Predict Crime Knowledge States in the Human Brain
2017 13 Mar
A multi-institutional research team has discovered that brain imaging can reveal whether someone is acting in a state of knowledge about a crime. The discovery will not have a bearing on court proceedings, but it is an inroad in the emerging field of "neurolaw," which connects neuroscience to legal rules and standards. The research is published in... Read more
Brain Imaging Links Alzheimer’s Decline to Tau Protein
2016 16 May
A buildup of plaque and dysfunctional proteins in the brain are hallmarks of Alzheimer’s disease. While much Alzheimer’s research has focused on accumulation of the protein amyloid beta, researchers have begun to pay closer attention to another protein, tau, long associated with this disease but not studied as thoroughly, in part, because scientists...

MRI Shows ‘Brain Scars’ in Military Personnel with Blast-related Concussion
2015 15 Dec
MRI shows brain damage in a high percentage of active duty U.S. military personnel who suffered blast-related mild traumatic brain injury (MTBI), or concussion, according to a study published in the journal Radiology . Researchers used MRI to study 834 military service members with MTBI related to blast injuries. MRI scans revealed the presence of... Read more
