Imaging of Electrical Properties by MRI: Investigation of Age-Related Changes (ELECTRA)

June 11, 2026 updated by: BRAUN Marc, Central Hospital, Nancy, France
The goal of this study is to build a database of personalized EP (Electrical Properties) maps (accounting for age, anatomical location, and tissue complexity), obtained via MRI, to improve electromagnetic safety assessments, especially in the context of MRI. The EP values derived from this study are expected to be more accurate than current literature values, leading to more realistic specific absorption rate (SAR) modeling and improved patient safety. To investigate age-related differences, the study will include three distinct age groups.

Study Overview

Status

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Estimated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

Yes

Inclusion Criteria:

  • Person aged between 6 and 12, 20 and 40 years or aged 70 years and above
  • Person affiliated with a social security scheme or beneficiary of such a scheme
  • Person, or parent/legal guardian in the case of minors, who has received full information about the organization of the study and has signed the informed consent form

Exclusion Criteria:

  • Contraindication to undergoing an MRI examination or the presence of an MRI-incompatible medical device
