Abstract:BackgroundMagnetic resonance diffusion-weighted imaging (DWI) is the most sensitive modality for ischemic stroke diagnosis. However, DWI may fail to detect ischemic lesions in a proportion of patients.MethodsFollowing PRISMA statement, a systematic search of Medline, Embase, and Web of Science was conducted until January 3, 2024.
