Description of intervention(s) / exposure
Adult patients (>18 years-old) presenting to the recruiting comprehensive stroke centres with acute stroke with anterior circulation large vessel occlusion considered for or receiving reperfusion therapies will be recruited for additional serial MRIs and blood tests with follow-up period up to 12 months (performed at MRI at 2-hours post-treatment, 24-72hours, 3 months & 12 months and blood tests at baseline, 2-hour and 24-72hours post-treatment ) as determined by participant's consent to continue attending MRIs.

Summary
Brief summary
The study is an Australian multicentre prospective imaging study performing multiparametric MRIs after acute reperfusion treatment for anterior circulation large vessel occlusion with cerebral perfusion, microstructural, metabolic and functional assessment at multiple follow-up time points.

The project has received ethical approval from the Melbourne Health Human Research Ethics Committee (HREC). The HREC confirms that your proposal meets the requirements of the National Statement on Ethical Conduct in Human Research (2007).
