Manufacturer Narrative

Siemens completed the investigation of the reported event.As previously reported, a companion of the patient entered the magnet room (mri room) with a loaded weapon (pistol) and an extra magazine which were attracted by the magnetic field of the mri.The companion did not inform the clinic that he was carrying a weapon.There was an accidental firing of the weapon, whose projectile lodged in the lower right side of the companion's back.There was no damage to other people who were at the scene, including the patient who was having the mri exam.The injured person was attended by the medical team on site and transferred to another hospital.Later, siemens was informed that the injured companion died on (b)(6) 2023, because of this injury.We assessed the complained event and concluded that the cause of this event was the introduction of ferromagnetic pieces into the mr examination room and therefore a user error.Due to the strong magnetic field, special safety measures must be adhered to prevent injuries.Therefore, the corresponding magnetom operator manual and the magnetom system owner manual provide clear instructions and warnings regarding both magnetic field hazards and training of personnel with regards to mr safety.However, the responsibility to instruct personnel and patients who have access to the mr examination room about magnetic field hazards lies with the customer.The manuals state that only equipment specified or recommended for use in the controlled area (mr examination room) shall be used.The introduction of ferromagnetic objects into the magnetic field is contrary to the statements given in the operating instructions.Furthermore, special warning signs are posted at the facility entrance of the controlled access area mri room.
