Hi there. Thank you for your question. Believe me, a very important one! Both Open and closed MRI units are magnets and work in a very similar way to construct an image of our body parts and tissues. However, Open MRI units work with low strength magnetic fields. This strenght is measured in units called Teslas (T). For example, Open MRI units strength range from 0.23T to 0.5T as opposed to closed MRI units that go from 1.0 to 3T or above. Rule of thumb: the greater the magnetic field, the better will be the signal acquired from the tissues to obtain better sensitivity of disease processes, better anatomic detail, and better tissue contrast. Unfortunately, due to the magnet size and strength, we still do not have the capability to build it in an open enclosure. Open MRI units are still useful in claustrophobic patients or bigger patients that cannot fit in a regular closed unit. In general, both you and your doctor can benefit more from the detail from a closed High Field strength unit.
