Magnetic Resonance Imaging (MRI)
Magnetic Resonance Imaging, or MRI, is an advanced method of generating clear images of the body without the use of X-rays. This technology helps physicians detect developing diseases or abnormalities early on.
MRI uses a powerful, harmless magnetic field and radio waves to produce detailed images of body structure, such as the brain, spine, extremities and other organs.
A state-of-the-art magnetic resonance imaging machine at Banner – University Medical Center Phoenix promises greater patient comfort through its reduced acoustic noise, wider and shorter “bore,” and lack of needed contrast.
The MRI system has been designed with features to improve patient comfort, including a large 71-centimeter bore (opening).
The fact that a larger bore can accommodate larger patients reduces the claustrophobic experience dramatically.
The system has also been equipped with the Pianissimo technology to dramatically reduce acoustic noise (by 90 percent), which can otherwise be a significant cause of discomfort during exams.
Finally, contrast-free imaging is important for patient safety and cost because gadolinium - the most common contrast agent used for MRI and MRA exams - is an additional cost to both the patient and the hospital. The patient also avoids intravenous injections during the procedure for many exams.
Banner – University Medical Center Phoenix uses this MRI for diagnosing a host of diseases, but its main use is for detecting breast and other cancers. Once a patient has had abnormal mammogram result, an MRI is often ordered to acquire cross-sectional images of the breast. A computer will compile these scans into highly detailed 2-D and 3-D images.
