Abstract
:1. Introduction
2. Materials and Methods
2.1. Transmit RF Coil Modeling
2.2. Numerical Human Body Models and RF Exposure Scenarios

4. Conclusions
- The patient assistants must not hold the patient’s body during the MRI scans unless otherwise instructed;
- If patient contact is required, the patient assistants must wear electrically insulated gloves whenever they are in the MRI scan room;
- The patient assistants must not touch any cables, equipment, or electronics of the MR scanner, even wearing insulating gloves.
