title: Magnetic resonance imaging of the olfactory apparatus.
abstract: We review the normal anatomy of the olfactory system with special emphasis on its extraaxial portions. Pathological processes affecting this cranial nerve are divided into those that do not require imaging and those that do. Processes in which patients benefit from imaging, mostly with magnetic resonance, include suspected tumors and congenital abnormalities.
