Presence of Acute Ischaemic Lesions on Diffusion-Weighted Imaging Is Associated with Clinical Predictors of Early Risk of Stroke after Transient Ischaemic Attack

Abstract

Presence of recent ischaemic lesions on DWI correlates with validated clinical scores for risk of stroke after TIA in patients scanned subacutely. Future prognostic studies of DWI after TIA should adjust for the risk scores to determine the independent predictive value of DWI and hence the likely role of DWI in refinements of the scores.
