Every year, millions of patients undergo magnetic resonance imaging scans, better known as MRI exams, in an effort to diagnose everything from joint pain to cancer.
An MRI is a test that produces very clear images of organs or other tissues in the body by using a magnet and pulses of radio wave energy. In this way, an MRI can detect changes in the structure of organs or other tissues, which may indicate inflammation, infection or other, more serious illnesses.
For many people, this procedure spurs images of a long, enclosed and often noisy tube that requires patients to remain still for up to an hour. Closed or cylindrical MRI systems can cause apprehension and severe anxiety in a large number of patients - especially children and those suffering from claustrophobia. It's a situation that even the most fearless person may find difficult to handle.
However, quieter, ultra-short- bore MRI systems are making exams much more comfortable for patients. For example, Toshiba's Vantage open MRI system uses an ultra-short magnet that provides high-quality images quicker and is extremely spacious. Children usually feel more at ease during an open MRI exam when loved ones can be nearby to comfort them during the procedure. The system also reduces scan noise by 90 percent, making for a quieter, more pleasant examination.
An MRI provides doctors with more information than an X-ray, ultrasound or CT scan - all without the use and possible harmful side effects of radiation. A typical MRI procedure can take anywhere from 30 minutes to an hour.
