Positron Emission Tomography and Nuclear Magnetic Resonance Imaging: New Perspectives in Neuroimaging

  • G. Di Chiro
Conference paper


The rise of nuclear magnetic resonance imaging (NMR or MRI) to a preeminent position among the neuroimaging methods has brought about lively debate among the cognoscenti on the advantages, if any, of this diagnostic modality. For reasons which are rather complex, and not always solely “science motivated,” MRI is being frequently pitted against positron emission tomography (PET). This is indeed an unlikely and, superficially, an unevenly matched confrontation. MRI has already recruited legions of practitioners with experts, or soi-disant experts, multiplying by the day. In contrast, the number of investigators who actually deal with PET represents an exiguous maniple. The MRI systems in operation worldwide are already many more than the pitifully few PET units which are mostly “research” dedicated. Also, relatively few neurologists and neurosurgeons, and even fewer neuroradiologists, could point to clinical applications of PET useful in the everyday practice of medicine. Thus the contraposition MRI-PET must find its justification in different aspects than the relative diagnostic merits.
