Overview

An MRI is the first-line imaging if the cause of vertigo is suspected to be central in origin.

MRI

• MRI is superior to a CT scan due to its ability to visualize the posterior fossa.
• Neuroimaging should be conducted if vertigo is accompanied by new onset headache, neurological signs and symptoms, normal head impulse test and acute deafness.
• MRI can identify various causes of central vertigo:
  • Vertebrobasilar insufficiency
  • Caudal cerebellar infarcts
  • Cerebellar artery insufficiency
  • Subclavian steal syndrome
  • Cerebellopontine angle tumor
