Predictive Value of PET/MR Indicators for Early Detection of Ischemic Brain Changes Following carotid artery stenting

Motivation: Aiming to bridge the diagnostic gap in predicting perioperative ischemic lesions post-CAS, crucial for preempting recurrent strokes. Goal(s): To pinpoint predictive markers on DWI for new ischemic brain lesions within 3 days post-CAS. Approach: Employed a retrospective analysis of preoperative PET/MR imaging in 47 CAS patients, correlating with postoperative DWI outcomes. Results: Identification of high PET SUVmax, SCAIL scores, and complex plaques as significant predictors of new ischemic lesions, offering a strategic tool for early high-risk patient detection. Impact: This study aids clinicians in stratifying stroke risk, influencing patient management and treatment tailoring. It opens avenues for precision medicine in stroke prevention and underscores the need for advanced imaging in preoperative assessments.
