Open MRI is designed so that the magnet does not completely surround you; it is open on both sides with a magnet above and below you. This type of unit is especially helpful for examining patients who are fearful of being in closed spaces (claustrophobic) and is also more accommodating for larger patients.
If additional comfort is desired, a family member may accompany you during your exam. However, certain types of exams cannot be performed using the Open MRI. Your physician will determine the best magnet for your needs.
