Wang R, Wang GJ, Goldstein RZ, Caparelli EC, Volkow ND, Fowler JS et al. (2010). "Induced magnetic force in human heads exposed to 4 T MRI". J Magn Reson Imaging 31 (4): 815-20. DOI:10.1002/jmri.22125. PMID 20373424. Research Blogging[e]

Describes a measurement of magnetic field gradients and magnetic forces, based on FLASH-MRI data obtained at 4 T from 118 healthy human subjects (of which 100 males) aged between 18 and 60 years. Concludes that "the induced magnetic force is highly significant in the eyeballs, orbitofrontal and temporal cortices, subcallosal gyrus, anterior cingulate as well as midbrain and brainstem (pons), regardless of subjects' age or gender.
