Use of Imaging to Guide Endovascular Stroke Treatment

An observational study suggests that magnetic resonance imaging can be useful to guide patient selection for endovascular treatment up to 12 hours after stroke onset.

Endovascular treatment for acute stroke remains controversial, because recanalization does not necessarily lead to good clinical outcomes. To examine the potential for use of imaging to guide patient selection and improve outcomes after endovascular therapy, researchers prospectively studied patients eligible to undergo endovascular treatment within 12 hours after an acute stroke. Participants underwent multimodal magnetic resonance imaging (MRI) before and within 12 hours after the procedure, and at hospital discharge (or day 5). The investigators used a computer program and blinded personnel to identify perfusion-diffusion mismatch (“target mismatch”) on the images.

Of 99 participants, 75% had mismatch on the baseline image. Those without …
