Evaluate the role of arterial spin labeling in acute stroke management compared to diffusion tensor imaging.
Included 100 patients with hyperacute and acute ischemic stroke
Conducted clinical assessments and used multiple MRI techniques including ASL and DTI
Correlated imaging findings with clinical outcomes at 3 months using NIHSS score
Relative CBF from ASL showed 89% sensitivity and 88% specificity for favorable outcomes
Optimal cut-off values were >48% for rCBF and >20 mL/100 g/min for absolute CBF
38 out of 42 patients with intact FA tracts had a significant reduction in NIHSS score at follow-up
