Like a genetic profile, a functional magnetic-resonance image (fMRI) of the brain can contain information that a patient wishes to keep private  An fMRI of a brain also contains enough information about a patient' s skull to create a recognizable image of that patient' s face
A genetic profile can be linked to a patient only by referring to labels or records
Patients are more concerned about threats to privacy posed by fMRIs than they are about those posed by genetic profiles.
