Abstract

Functional MRI (fMRI) has tremendous clinical potential that is as yet unrealized. There are tremendous unmet medical needs that fMRI could address with significant benefit to human health. However, both medical and technical barriers prevent this benefit from accruing today. Technical barriers may be the reflexive focus of the current practitioners of fMRI, a technically savvy group. However, the real challenge lies in the medical realm, and this will require multidisciplinary and interdisciplinary work since the technical aspects of fMRI are ahead of the medical aspects. This can be seen in a range of diseases from Alzheimer's disease to schizophrenia to ischemic stroke: in each case our ability to image changes with fMRI outstrips our ability to do anything useful for the patient with them. Diagnostic imaging will always be linked in the clinic to therapeutic choices, and therefore the most powerful approach to link fMRI more directly to the clinic will be to tie fMRI to therapy development and implementation.
