title: Radiological appearances in olfactory dysfunction: pictorial review.
abstract: BACKGROUND
  Olfactory dysfunction is a common condition that may in some cases require imaging to investigate a potential underlying cause.
  
  
  OBJECTIVE
  This review describes the anatomy of normal olfaction and illustrates the pathological substrates of olfactory dysfunction amenable to imaging.
