MRI
For diagnosing ischemic stroke in the emergency setting:[1]
- sensitivity= 83%
- specificity= 98%
MRI scan
- sensitivity= 81%
- specificity= 100%
For detecting chronic hemorrhages, 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.
