Predictive Multimodal MRI Factors in Subacute Cerebral Artery Occlusiontreated by Thrombectomy (PIMISUTT)

This study examines whether MRI brain scans taken before a procedure called thrombectomy (a catheter-based procedure to remove a blood clot from a brain artery) can predict how well a patient will recover afterward. The study focuses on patients with a stroke caused by a middle cerebral artery blockage, and aims to identify imaging markers that predict which patients benefit most from thrombectomy, and which may face greater risks. Participants will have specialized MRI scans taken before and after thrombectomy, and their recovery will be tracked over time. This could help doctors make better treatment decisions in future stroke cases. **You may be eligible if you:** - Are 18 years of age or older - Are hospitalized at Poitiers University Hospital - Have been diagnosed with an acute middle cerebral artery occlusion (stroke) by CT scan or MRI - Have a stroke severity score (NIHSS) of 6 or above at admission - Are scheduled to receive thrombectomy (with or without clot-dissolving medication) **You may NOT be eligible if you:** - Cannot be properly informed about the study (you or your relatives) - Have existing cognitive impairment that makes MRI interpretation difficult - Cannot undergo MRI due to contraindications (e.g., pacemaker, metal implants) - Are too unstable to tolerate an hour-long examination **Talk to your doctor** if you or a family member is being treated for a stroke and you want to understand what research is available to improve outcomes.
