The higher the strength of the magnetic field the higher quality of the image being produced. Because of this, open MRIs would sometimes produce images that were of a lower quality or less precise. It used to be fairly difficult for open MRIs to accommodate the most powerful magnets that could be used on closed MRIs. The term “open” may be used to describe MRI scanners that have a shorter and wider cylinder, which provides some comfort, but not the same experience as a fully open one. MRIs with open sides have magnets above and below the patient, whereas closed MRIs have magnets surrounding the patient. A person with wide shoulders or a significant amount of weight cannot also be accommodated. It can be challenging for individuals with claustrophobia to be in such a small, enclosed space.
In conventional MRIs, patients are slowly sent through a hollow, cylindrical structure. The open MRI machine is configured differently from a conventional MRI machine, primarily to improve patient comfort. In contrast to CT (computed tomography), MRI provides better contrast without radiation when imaging the liver, bile ducts, pancreas, and kidneys. Additionally, it helps physicians assess soft tissue masses, bone tumors, cysts, and herniated or bulging discs in the spine, as well as sports injuries. A variety of disorders can be diagnosed with it, such as multiple sclerosis, brain tumors, tumors of the pituitary gland, strokes at their earliest stages, tendonitis, and infections affecting the brain or spine. Radiofrequency and high-power magnets are used in an MRI to capture images of bones, tissues, and organs. The use of magnetic resonance imaging (MRI) is one of the safest, non-invasive methods for viewing the interior of the human body.
