Open MRI

An Open MRI uses the same technology as a Closed MRI, but has a much larger opening compared to a Closed MRI. In recent years Open MRI technology has made huge improvements in magnet power, computing capacity, and image construction that Open High Field MRIs such as the Hitachi Oasis can produce images on par with Closed High Field MRIs. Magnetic resonance imaging (MRI) is a test that uses a magnetic field and pulses of radio wave energy to make pictures of organs and structures that are inside the body. MRIs allow physicians to see extremely detailed images of the inside of the human body that cannot be seen with other diagnostic imaging. An MRI is one of the safest, most comfortable imaging techniques available.

What to expect during the MRI?

  • You will be asked to lay down on a mechanical table that is inserted into the machine to scan the desired body region.
  • The scan generally takes 20 to 30 minutes depending on the type of scan being performed. During the scan, please try to remain calm and breathe normally as large body movements can interfere with the MRI results.
  • During the MRI you will hear loud thuds and clicking noises coming from the machine, these are completely normal and are not a cause for concern.
  • You will be in constant contact with the MRI technologist should there be any problem or concern during your exam.
  • After your MRI, you may return home or to work. DFW MRI will contact your doctor within 24 to 48 hours with the results of your study. Only your doctor is authorized to discuss your MRI results with you.
