WebThe term functional MRI (fMRI) usually refers to the imaging of brain activation using various MR techniques. By the late 1980's it was known that regional cerebral blood flow increased near areas of neuronal activity, and low resolution PET studies had already documented this phenomenon in humans. WebIt was his use of nuclear magnetic resonance in the study of molecules, solutions, and solids that led to the application of NMR technology to medicine, which eventually led to the development of the MRI system. However, Raymond Damadian is often credited as one of the main contributors to the invention of the MRI system as well. raw picture format
