Abstract：
:The olfactory system and especially the olfactory bulb (OB) as the first relay in the olfactory system represent highly plastic structures. For example, OB volume partly reflects the degree of afferent neural activity. Research indicates that smell deficits leading to a reduced sensory input result in structural changes at the level of the OB. Reduced OB volumes also may be considered characteristic of parosmia. Apart from discussing the clinical implications of these findings, the radiologic basics for assessment of olfactory-eloquent structures are addressed in detail.
