Well yes, it's primary modality for stroke worldwide and it's leading modality in France, just like I've said before.
> You're a little confused. You're using "sensitivity" to mean sensitivity of detecting ischemic stroke. MRI is the obvious follow-up. When available, worldwide. But it doesn't guide emergency treatment.
I would appreciate if you stopped using condescending tone. It does not guide emergency treatment decisions because in most cases it is not performed in emergency settings. When it is performed in this setting it is guiding treatment and MRI is included in stroke guidelines for cases where clinical diagnosis is not clear (and these cases are not that rare). Why is it not widely adopted? Mostly logistic reasons (which can be overcome - like they were in France) and because TOF-MRA is generally worse than CTA. It has others positives apart from higher sensitivity though, e.g. you can use FLAIR/DWI mismatch in wake-up strokes which are VERY common (obviously perfusion serves generally same purpose).
