Carotid Plaque Characterization Using Innovative Ultrasound Techniques

"This procedure will take place once during the patient's CARPUS first visit (Croix Rousse hospital (Hospice civils de Lyon).~A peripheral venous line of the cathlon 24 G type with tap without tubing will be inserted by a nurse. A blood sample will be taken at the same time to check creatinine levels before the MRI scan and to record the patient's cholesterol levels for the eCRF."

"This procedure takes place once immediately after the intervention 1. The patient will first have an ultrasound acquisition with the clinical ultrasound scanner (\~5 minutes) in order to locate the plaque. An acquisition with the research ultrasound scanner and matrix probe will then be performed for measurement for ultrasound spectroscopy (\~5 minutes).~An injection of 2.4 ml Sonovue followed by 10 ml saline will be performed during acquisition with the research ultrasound scanner for ultrasound localization imaging measurement (\~10 minutes).~The patient must remain under observation (in the waiting room) for 30 minutes after the examination."

"This procedure will take place once during the patient's CARPUS second visit (Pierre Wertheimer hospital (Hospice civils de Lyon)).~The patient is greeted in radiology, and his/her identity and absence of contraindications are verified.~A peripheral venous line of the cathlon 24 G type with tap without tubing will be inserted by a nurse.~Injection of gadolinium and MRI examination of the plaque used in clinical routine."
