Additional information given to a multimodal imaging stroke protocol by transcranial Doppler ultrasound in the emergency room: a prospective observational study.
Transcranial Doppler (TCD) ultrasound can demonstrate dynamic information. We aimed to evaluate whether TCD generates useful additional information in the emergency room after a multimodal stroke imaging protocol and also whether this modified the management of patients with cerebral infarction. ⋯ TCD can provide additional information to a multimodal acute ischemic stroke imaging protocol in a third of patients. This can result in changes in the management in some of these patients.

Presence of deep white matter lesions on diffusion-weighted imaging is a negative predictor of early dramatic improvement after intravenous tissue plasminogen activator thrombolysis.
The impact of deep white matter lesions observed at the corona radiata on diffusion-weighted MRI (DWI-W lesions) on the clinical recovery of patients after tissue plasminogen activator (tPA) therapy is unclear. Our goal was to elucidate whether DWI findings before tPA could predict clinical recovery. ⋯ DWI-ASPECTS and DWI-W lesions appear to be useful tools for predicting early dramatic improvement.
