ESOC 2025 | The evolving role of MRI in the diagnosis of TIA
Philipp Bücke, MD, MSc, University Hospital Bern, Bern, Switzerland, comments on the evolving role of magnetic resonance imaging (MRI) in the diagnosis of transient ischemic attacks (TIAs). Dr Bücke notes that MRI has evolved as the primary imaging tool for patients with TIA, as computed tomography (CT) scans may not accurately distinguish between strokes and TIAs. This interview took place at the 11th European Stroke Organisation Conference (ESOC) in Helsinki, Finland.

There are not that many data actually. I mean it’s interesting because just only recently it was said that we need an MRI for like TIA patients because it is not actually quite clear what a TIA is. That’s interesting. Of course we know for a long time that symptoms have to be transient and only there for 24 hours but like then if you just do a CT scan for example we do not know whether there’s like a small stroke on the CT or in the brain or not...
There are not that many data actually. I mean it’s interesting because just only recently it was said that we need an MRI for like TIA patients because it is not actually quite clear what a TIA is. That’s interesting. Of course we know for a long time that symptoms have to be transient and only there for 24 hours but like then if you just do a CT scan for example we do not know whether there’s like a small stroke on the CT or in the brain or not. And that’s why the MRI has actually evolved as the primary imaging tool for TIA patients. And so therefore the data that we have is mainly CT-based and so we are not sure often whether this is a stroke or not but in this CT data using CT perfusion we do know that for example patients with a perfusion deficit are at risk of having higher strokes or it has been shown actually but yet we do not know if they were stroke patients in the beginning or if they were just TIA patients in that case.
