From GE Healthcare;
the New Signa Profile/i is a patient friendly open MRI system that virtually eliminates patient anxiety and claustrophobia, without compromising diagnostic utility.

From Philips Medical Systems;
Panorama 0.6 T is the Philips Mid-Field Open MRI system. It is the most open MR scanner in the market, optimized for patient comfort and faster reconstruction time.

From Philips Medical Systems;
the Intera-family offers with this member a wide range of possibilities, efficiency and a ergonomic and intuitive serving-platform. Also available as Intera CV for cardiac and Intera I/T for interventional MR procedures.
The scanners are also equipped with SENSE technology, which is essential for high-quality contrast enhanced magnetic resonance angiography, interactive cardiac MR and diffusion tensor imaging (DTI) fiber tracking.
The increased accuracy and clarity of MR scans obtained with this technology allow for faster and more accurate diagnosis of potential problems like patient friendliness and expands the breadth of applications including cardiology, oncology and interventional MR.

From Philips Medical Systems; the Intera-family offers with this mid field system maximum efficiency, flexibility and performance. All Philips MR products contain SENSE (coil SENSitivity Encoding) technology - that increases scanning speed.

There are different types of contraindications that would prevent a person from being examined with an MRI scanner. MRI systems use strong magnetic fields that attract any ferromagnetic objects with enormous force. Caused by the potential risk of heating, produced from the radio frequency pulses during the MRI procedure, metallic objects like wires, foreign bodies and other implants needs to be checked for compatibility. High field MRI requires particular safety precautions. In addition, any device or MRI equipment that enters the magnet room has to be MR compatible. MRI examinations are safe and harmless, if these MRI risks are observed and regulations are followed.

Safety concerns in magnetic resonance imaging include:

It is important to remember when working around a superconducting magnet that the magnetic field is always on. Under usual working conditions the field is never turned off. Attention must be paid to keep all ferromagnetic items at an adequate distance from the magnet. Ferromagnetic objects which came accidentally under the influence of these strong magnets can injure or kill individuals in or nearby the magnet, or can seriously damage every hardware, the magnet itself, the cooling system, etc.. See MRI resources Accidents.
The doors leading to a magnet room should be closed at all times except when entering or exiting the room. Every person working in or entering the magnet room or adjacent rooms with a magnetic field has to be instructed about the dangers. This should include the patient, intensive-care staff, and maintenance-, service- and cleaning personnel, etc..
The 5 Gauss limit defines the 'safe' level of static magnetic field exposure. The value of the absorbed dose is fixed by the authorities to avoid heating of the patient's tissue and is defined by the specific absorption rate. Leads or wires that are used in the magnet bore during imaging procedures, should not form large-radius wire loops. Leg-to-leg and leg-to-arm skin contact should be prevented in order to avoid the risk of burning due to the generation of high current loops if the legs or arms are allowed to touch. The patient's skin should not be in contact with the inner bore of the magnet.
The outflow from cryogens like liquid helium is improbable during normal operation and not a real danger for patients.
The safety of MRI contrast agents is tested in drug trials and they have a high compatibility with very few side effects. The variations of the side effects and possible contraindications are similar to X-ray contrast medium, but very rare. In general, an adverse reaction increases with the quantity of the MRI contrast medium and also with the osmolarity of the compound.
