WebBackground and Purpose—Mismatch in lesion visibility between diffusion-weighted image and fluid-attenuated inversion recovery image (DWI–FLAIR mismatch) has been proposed as a biomarker for the estimation of ischemic lesion age. The actual onset in some patients with unclear-onset stroke (UnCOS) may be close to the first-found abnormal time. We WebA, T1-weighted image; B, T2-weighted image; C, fluid-attenuated inversion recovery (FLAIR) image. An 8 × 10-mm lesion involving the superior temporal cortex with extension to subcortical white matter is seen on the FLAIR image (arrow) but is poorly shown on the T1- and T2-weighted images.
