Overview

MRI

For diagnosing ischemic stroke in the emergency setting:[1]

MRI scan

sensitivity= 83%
specificity= 98%

MRI scan

sensitivity= 81%
specificity= 100%

For detecting chronic hemorrhages, an MRI scan is more sensitive.[2]

For the assessment of stable stroke, nuclear medicine scans SPECT and PET/CT may be helpful. SPECT documents cerebral blood flow and PET with FDG isotope the metabolic activity of the neurons.
