Brief Summary

The goal of this proof of concept study is to determine if the visualization of the middle cerebral artery and its perforators, through 3D transtemporal ultrasound imaging, is possible thanks to an off-line analysis by 3D ultrasound localization microscopy. Visualization of these vessels would allow us to conclude on the presence, or absence, of an ischemic stroke in the region of the middle cerebral artery. To answer the question asked, 20 participants who suffered a stroke will carry out a transtemporal ultrasound examination specifically for research in the 7 days following his stroke. The data obtained will be analyzed by the CNRS medical imaging laboratory, in order to characterize the presence of a stroke and to compare the data obtained with that of standard examinations (CT and MRI).

Eligibility Criteria

Inclusion Criteria: * Patient aged 18 and over * Hospitalized patient with ischemic stroke in the deep territory of the middle cerebral artery * Patient with lesion observable on MRI * Patient included between 24 hours and 7 days after the ischemic stroke * Patient with a temporal window which allows soundproofing of the polygon of Willis and the middle cerebral artery * Patient having signed free, informed and written consent * Patient affiliated to a social security system (excluding AME) Exclusion Criteria: * Contralateral middle cerebral artery territory stroke or contralateral middle cerebral artery occlusion * Patient with contraindication to Doppler ultrasound with contrast (right-left shunt, severe pulmonary arterial hypertension) * Patient with hypersensitivity to the active princip of Sonovue (sulfur hexafluoride) or these excipients * Patient with uncontrolled systemic hypertension * Patient with respiratory distress syndrome * Patient under guardianship or curatorship * Pregnant or breastfeeding patient (positive blood pregnancy test during hospitalization) * Patient with damaged skin at the temporal level * Patient having presented in the 7 days preceding inclusion an acute coronary syndrome or suffering from unstable ischemic heart disease
