Synopsis

Keywords: Stroke, Stroke

Motivation: To explore synthetic MRI's potential for improved stroke lesion characterization and metabolic activity prediction.

Goal(s): To Enhance stroke lesion visualization and to estimate regional metabolism via quantitative relaxation values in synthetic MRI.

Approach: 10 stroke patients underwent integrated PET/MR scanning. We compared tissue contrast in synthetic tailored contrast-enhanced composite images with conventional T2 FLAIR. Relaxometry values were used to build predictive models for PET SUV.

Results: Composite images significantly improved stroke lesion visibility compared to traditional methods. Relaxometry values successfully predicted metabolic activity within the lesion.

Impact: This study demonstrates the potential of synthetic MRI in stroke patients, offering improved
