assessment of cognitive functions
Assessment of cognitive disorders with an ultrasound examination performed in routine care during a day hospital.
Ultrasound examination
Ultrasound examination with Tissue Pulsatility Imaging (TPI) TPI is a relatively simple, rapid and non-invasive ultrasound examination which consists of applying a standard ultrasound probe to the acoustic window of the temporal bone to first measure the velocity of the middle cerebral artery in Doppler mode and secondly the cerebral pulsatility (CP) of a region of approximately 10cm2 centred on the middle cerebral artery in B-Echo mode. After collecting the information, the TPI examination will be performed by MRRC staff specially trained in TPI by engineers. The duration of the examination is between 20 and 30 minutes, including hardware installation. Four 30-second PC acquisitions will be collected per examination, with the patient lying supine on the bed in the day hospital room, then one measurement every minute for 3 minutes after standing.
