About this study

The new technical of ultrasonic exploration of this project purpose to validate the measurement of cerebral pulsatility by a new way called "Fast Cerebral Pulsatility Imaging" (FCPI).This will somehow determine the natural history of cerebral pulsatility during development adult to old age

Read the detailed description

Main objective

Phase 1:

-Study the in-vivo development of ultrasonic method in terms of quality of the acquisitions and intra-operator reproducibility.

Study the ease of positioning in relation to MRI and fusion of MRI and FCPI data via the neuro-navigation system

Phase 2:

-Study the variability of cerebral pulsatility of measured by "Fast Cerebral Pulsatility Imaging" or FCPI with age.

Secondary objectives

  • Compare the results of displacements cartography's and vascular cartography obtained by MRI (especially by Arteriel Spin Labelling = ASL)
  • Compare results of FCPI with results of cognitive tests of aging separating fluid functions (prefrontal) and functions called crystallized; and study the residual effect of age on cognitive tasks and speed of cognitive processing after taking into account the effect of the cerebral pulsatility
  • Compare results of FCPI with electrophysiological measures (PE EEG) describing the attentional control
  • Perform an exploratory analysis to highlight the propagating part of the brain displacement maps

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Phase 1 : to validate the technical procedure, we will appreciate several parameters

    • Time of implementation of procedure
    • Qualitative identification of anatomical landmarks of positioning in space of the US probe using neuro-navigation system; if available quantitative measure: x,y,z or distance to a region of interest(ROI)
    • Perfusion values: Cerebral Blood Flow of Willis' Circle in MRI
    • Signal to noise ratio
    • Amplitude (max displacement value), location (x,y,z of location of this max or distance to a ROI) of FCPI
    • Bandwidth of metrology of FCPI
    • Possibility to indentify the propagation phenomenon underlying to displacements (speed and attenuation of the shear wave)

    Measured: up to 8 days after consent

  2. Phase 2 : the primary outcome measures will be the maximum amplitude and the average amplitude of cerebral movements

    We hypothesize that the variables describing the FCPI will decrease with age. The primary outcome measures will be the maximum amplitude and the average amplitude of cerebral movements measured in µm in planes chosen previously (for example plan of Circle of Willis and a plane including the dorsolateral area of prefrontal cortex).

    Measured: up to 8 days after consent

Secondary outcomes (4)
  1. Phase 2 : Maps of cerebral displacementand tissular perfusion maps

    Maps of cerebral displacement obtained by ultrasounds (amplitudes in µm and location in mm) and tissular perfusion maps obtained by Arterial Spin Labelling (Cerebral Blood Flow in µL.g-1.mn-1)

    Measured: up to 8 days after consent

  2. Phase 2 : Measures of FCPI on the regions of interest and cognitive tests

    Measures of FCPI on the regions of interest: amplitude (maximum displacement values, µm) and location x, y, z, of the location of this maximum in mm, or distance to a region of interest) on the hand and cognitive tests on the other hand expressed with a numerical score for each test.

    Measured: up to 8 days after consent

  3. Phase 2 : Measures of FCPI on the regions of interestand measures of PE EEG

    Measures of FCPI on the regions of interest: amplitude (maximum displacement values, µm) and location x, y, z, of the location of this maximum in mm, or distance to a region of interest) on the hand and measures of PE EEG on the other hand expressed in terms of amplitude (µV), latency (ms), duration (ms)

    Measured: up to 8 days after consent

  4. Phase 2 : The signal to noise ratio

    The signal to noise ratio of maps speed (m/s) and attenuation α (cm-1) of the shear wave obtained by mathematical processing of displacement maps

    Measured: up to 8 days after consent

Questions about this trial

What is this clinical trial studying?

A study testing Fast Cerebral Pulsatility Imaging in people with Aging and Cerebral Pulsatility, run by University Hospital, Tours at 1 site in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 23 Dec 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Phase 1 : to validate the technical procedure, we will appreciate several parameters (time frame: up to 8 days after consent). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01737606, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 Dec 2025.
