Acute MRI in Transient Ischemic Attack

"Patients will have to spend additional 10min in the scanner.~Additional scan modalities used:~1. Perfusion without contrast: Arterial spin labeling (ASL) with the ability of showing signs of ischemia.~2. Diffusion tensor imaging (DTI): Has a higher sensitivity than DWI in displaying local ischemic lesions.~An overall 20min scan period."
