Should IV Thrombolysis be given in Patients with Suspected Ischemic Stroke but Unknown Symptom Onset and..., Many acute ischemic stroke (AIS) patients present with unknown time of symptom onset (UTO). In these situations, wake-up MRI protocols can guide treatment decisions: patients with DWI (diffusion-weighted imaging) but no fluid-attenuated inversion recovery lesion were shown to benefit from IVT (intravenous thrombolysis)., Many acute ischemic stroke (AIS) patients present with unknown time of symptom onset (UTO). In these situations, wake-up MRI protocols can guide treatment decisions: patients with DWI (diffusion-weighted imaging) but no fluid-attenuated inversion recovery lesion were shown to benefit from IVT (intravenous thrombolysis). However, initial MRI of some stroke patients is DWI negative, leaving it unclear whether this subgroup profits from IVT. Therefore, we aimed to compare the safety and efficacy of IVT in wake-up AIS patients with or without a DWI lesion in initial imaging., admin,
