Overview of the artificial intelligence roadmap: Future applications in brain research

Current Medicine Research and Practice, 2023
The use of artificial intelligence (AI) is an emerging technique in the early identification and categorisation of brain tumour. The currently used method, i.e., magnetic resonance image for the detection of tumour is a time–consuming and complex ...

Exploring in vivo human brain metabolism at 10.5 T: Initial insights from MR spectroscopic imaging

NeuroImage
Introduction: Ultra-high-field magnetic resonance (MR) systems (7 T and 9.4 T) offer the ability to probe human brain metabolism with enhanced precision. Here, we present the preliminary findings from 3D MR spectroscopic imaging (MRSI) of the human brain
