Overview
- CT scan is not the first-line imaging preferred to determine the underlying cause of central vertigo.
CT
- CT scan or computerized axial tomography (CAT) of head and/or labyrinth may be necessary to identify the central cause of vertigo: ischemic stroke, cerebellopontine angle tumor, multiple sclerosis.
- A negative CT scan cannot exclude the central cause of vertigo and it should be followed by an MRI.[1]
- CT scan has low sensitivity for identifying ischemic stroke as compared to an MRI.[1]
- If MRI is contraindicated then a thin cut CT scan can be used.
