FLAIR / Diffusion Mismatch



Acute ischemic lesions were judged by visibility on DWI and FLAIR imaging, which diagnosed DWI-FLAIR mismatch.
Acute ischemic lesion visibility was moderate on FLAIR imaging.

If an infarct seen on  diffusion and not seen FLAIR called FLAIR / Diffusion Mismatch indicate hyper acute infarct - reversible  ischemic changes and salvageable tissue or  tissue at risk.
If changes are marked on FLAIR indicate already infracted and non salvageable tissue.
