MRI is a test that uses a magnetic field and pulses of radio wave energy to create pictures of organs and other structures inside the body. This type of technology can yield different types of information than X-ray, computed tomography (CT) scans, or ultrasound, and often can reveal things that cannot be seen with other imaging methods.
To perform the MRI test, the area of the body being studied is placed inside a special machine that contains a strong magnet. Pictures from an MRI scan are digital images that 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. Sometimes contrast material may be used during the MRI scan to show certain structures more clearly.
Magnetic resonance imaging is done for many reasons, including the detection of tumors, bleeding, injury, blood vessel diseases, or infection, all reasons that could be contributing to a non-healing wound.
MRI is performed by the Diagnostic Imaging Department at Alameda Hospital. The test involves lying on a special table which may be slid inside a tube-shaped cylinder or an open scanner. Then a picture is taken of the area to see if infection or other abnormalities are present. An MRI is a painless test which takes about one hour to perform. There are no side effects of the test and the only discomfort which may be experienced is that of being still in a small space.
