The treatment benefit of alteplase in patients with a DWI‐FLAIR mri-guided thrombolysis for stroke with unknown time of onset ブログ mismatch seems not merely driven by the presence of a PWI‐DWI mismatch, although this analysis was underpowered. MRIでdiffusion highだがFLAIRで異常が描出されない場合に. Attempts have been done to use thrombolytic therapy in these patients. Fiebach, Christian Gerloff, Keith Muir, Norbert Nighoghossian, Salvador Pedraza, Claus Z. Yamaguchi T, Mori E, Minematsu K, Nakagawara J, Hashi K, Saito I, et al. Acute ischemic stroke (AIS) is the fourth leading cause of mortality and accounted for 5.

All the patients had an ischemic lesion that was visible on MRI diffusion-weighted imaging but no parenchymal hyperintensity on fluid-attenuated inversion recovery (FLAIR), which indicated.
