Super-Resolution Ultrasound of the Brain in 3D

Pilot Study of the Characterization of Subacute Ischemic Cerebrovascular Accidents in the Region of the Middle Cerebral Artery by 3D Ultrasound Localization Microscopy (ULM) with a Research Ultrasound System and Non-marketed 2D Matrix Probe.

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).

Conditions

• Cerebral Stroke

Interventions

Type	Name	Description
PROCEDURE	Transtemporal ultrasound with contrast product (Sonovue)	During their hospitalization and in the 7 days following their stroke, all patients will perform a transtemporal ultrasound including the use of Sonovue contrast product. The examination will last 1 hour and will be carried out on the opposite side of the stroke then on the side of the stroke
