MRI or Magnetic resonance imaging is not a one-size-fits-all system. There are different machines that have differences in image quality, sizing of opening, and overall preferences of patients. Below, we’ll take a look at the differences and benefits of the Closed Bore, Open Bore and Wide Bore MRI.
Closed Bore MRI
Closed Bore MRIs are usually high-field systems that create crisp imaging with a high speed. During a Closed MRI procedure patients will lie down and are inserted into the opening or the “bore” in the MRI scanner, which is the smallest opening of the machine, measuring only about 60 cm. It can feel like being in a small tunnel. Because of the size constraints of the machine, a closed bore MRI can sometimes make patients feel claustrophobic and imposes size restrictions on other patients.
Open MRI is exactly like the name sounds. It is open on three to four sides depending on the type of machine. The Open MRI allows for patients who are too large for the closed-bore MRI or who are claustrophobic to be easily scanned. Before the introduction of this machine, larger patients would not be able to receive MRI scanning. However, the open space of the machine does diminish the size of the magnet, which can reduce image quality when comparing to the imaging from the Closed Bore MRI. Another difference is the timing of the imaging, which can oftentimes be twice as long as the Closed Bore System.
Wide Bore MRI
Wide Bore MRI is basically considered a combination of the two, though it is often referred to as an Open MRI. There is more space, similar to the Open MRI, but allows for the better quality imaging from a larger magnet and the shorter procedure duration as found in the Closed Bore MRI. The opening in this machine is around 10 cm larger than the Closed Bore MRI, which is beneficial for larger or more claustrophobic patients. Still, the imaging in the Wide Bore MRI does not provide the imaging that is as detailed and clear as the Closed Bore MRI.
How do you know which MRI is right for you?
It depends both on your personal preference and the recommendation of your doctor. The Wide Bore is recognized as a standard for most routine imaging, but the image quality from the Open Bore is continually improving.
