متن کاملBringing Kallmann syndrome into focus.
Three articles ( 1-3) in this issue of AJNR bring the power of magnetic resonance (MR) to bear on the problem of neuroimaging in Kallmann syndrome (KS). These investigators provide the most detailed views of KS olfactory pathology that can be obtained outside of the anatomy laboratory, opening a new window on the study of this disease. The principle phenotypic features of KS, anosmia and hypogo...
