Performance Evaluation by Magnetic Resonance Imaging (MRI) of Intramuscular Thigh Injections With 3 Configurations of Needle-free Injector (ZENEO®)

Study Overview
=================
Brief Summary
-----------------
The aim of this study is to evaluate the intramuscular nominal thigh injection performance and the low threshold strength thigh injection (by evaluating 2 low threshold : upper limit and lower limit). All participants will receive an intramuscular nominal thigh injection, and half of the participants will receive an intramuscular low threshold (upper limit) strength thigh injection, while the other half will receive an intramuscular low threshold (lower limit) strength thigh injection.
