Brain MRI: How to read MRI brain scan | Kenhub MRI is the most sensitive imaging method when it comes to examining the structure of the brain and spinal cord. It works by exciting the tissue hydrogen protons, which in turn emit electromagnetic signals back to the MRI machine. The MRI machine detects their intensity and translates it into a gray-scale MRI image. New MRI probe can reveal more of the brain's inner workings Using this technique, which involves genetically targeting the MRI probe to specific populations of cells in animal models, the researchers were able to identify neural populations involved in a circuit that responds to rewarding stimuli. The new MRI probe could also enable studies of many other brain circuits, the researchers say. MR Image Classification for Brain Tumor Texture Based on Pseudo-Label ...
