What is MRI and how does it work?
Magnetic Resonance Imaging is a method of obtaining detailed pictures, or images, of internal body structures without the use of radiation or radioactive substances of any kind. This is accomplished by placing the patient in a magnetic field while harmless radio waves are turned on and off. This causes the body to emit its own weak radio signals which vary according to tissue characteristics. These signals are picked up by a sensitive antenna and fed to a computer which produces detailed images of the body for interpretation by our staff of board certified radiologists and then reported to your physician.
Pictures from an MRI scan are digital images comprised of “slices” compiled from the MRI procedure which can be saved and stored on a computer for more study. The images also can be reviewed remotely, such as in a clinic or an operating room. In some cases, contrast material may be used during the MRI scan to show certain structures more clearly.
