Healthy Subjects

Investigational drug(s) / intervention(s)

Magnetic Resonance Imaging (MRI) examination

Magnetic Resonance Imaging (MRI) examination: MRI examination of the head and neck, and torso for the measurement of electrical properties

Study 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. 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.
