Imaging of Electrical Properties by MRI: Investigation of Age-Related Changes
A study testing Magnetic Resonance Imaging (MRI) examination in people with Healthy Subjects, run by Central Hospital, Nancy, France at 2 sites in France.
Trial summary
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. Read more about this study

About this study
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.

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.

Questions about this trial
What is this clinical trial studying?
A study testing Magnetic Resonance Imaging (MRI) examination in people with Healthy Subjects, run by Central Hospital, Nancy, France at 2 sites 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 3 inclusion and 4 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: looking for participants now, as of the sponsor's last update on 12 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites 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?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Marc BRAUN, MD, PhD (0383157823 ext. +33, m.braun@chru-nancy.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Conductivity in S/m at the head level in subjects aged 6 to 12 years (time frame: Baseline (J0)). The study lists 9 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 12 Jun 2026.
