Grenoble Alpes University Hospital Center (CHU)

Status: Enrolling

Conditions: MRI; Sequence Optimization; Physiological Measurement

Treatments: Device: MRI Protocol

Study type: Interventional

Funder types: Other

Identifiers

Details and patient eligibility

About

IRMaGe is a Joint Service Unit (UMS) which provides users of brain exploration equipment (clinical MRI and preclinical, TMS, EEG, NIRS and metabolomics). The methods available on this equipment are intended to evolve according to the most recent discoveries and this protocol aims to frame the developments necessary around clinical MRI for IRMaGe can continue to offer tools at the cutting edge of technology.

Full description

The studies will be carried out on healthy subjects and voluntary patients, who will have given their consent. Their main objective will be the development and optimization of sequence parameters or design stimulation paradigms in order to optimize the quality and relevance of the images produced taking into account the parameters anatomical, functional or metabolic while respecting the experimental constraints imposed by the protocol concerned (equipment of experimentation, additional physiological measurements, etc.). The main judgement criteria will be measurements inherent in the MRI sequence and a physiological measurement associated in the protocol concerned

Enrollment: 600 estimated patients

Sex: All

Ages: 18+ years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

• Participants with normal or corrected vision
• Participants affiliated to a social security scheme or beneficiaries of such a scheme
• Participants with French as their mother tongue
• Participants who have given the signed informed consent before carrying out any procedure related to the study.
• Volunteer patients will be recruited as part of their follow-up at the CHU. Their pathology will be in agreement with that of the research protocol to be optimized.
