Instructions for Safe Use
Pre-screening of patients
The user must make a careful evaluation of the risks associated with the
personal and clinical history of patients, their psychological and physical
conditions and profession before performing an examination using the
O-scan system.
The evaluation should identify any contraindications that would preclude
the examination and any special precautions that should be taken before
or during the examination.
CONTRAINDICATIONS
The M.R. examination is contraindicated :
☛
for patients with implants or internal devices that are electrically,
magnetically or mechanically activated
☛
for patients who rely on electrically, magnetically or mechanically
activated life support systems
☛
for patients with implanted surgical clips or metal objects in the cranial,
ocular and vascular areas, unless the supervising physician has
ascertained that the clip or implant is not ferromagnetically active.
W a r n i n g
Never examine patients with pacemakers, neurostimulators, infusion
pumps, cochlear implants or other active systems.
Never allow these patients to enter the controlled access area.
Magnetic and RF fields produced by O-scan may interfere with
electrically, magnetically or mechanically activated devices.
Magnetic and RF field interference may result in serious injury and
may damage or alter the proper functioning of the devices.
W a r n i n g
Do not examine patients who have intracranial aneurysm clips, ocular
and vascular implants or other implanted ferromagnetic objects
unless the supervising physician has ascertained that they are MR
Conditional.
Never allow these patients to enter the controlled access area.
The magnetic field exerts a force of attraction on ferromagnetic
objects within the field.
This force may move or dislodge surgical clips or other ferromagnetic
implants, causing serious injury or death.
