| [Visitor (113.218.*.*)]answers [Chinese ] | Time :2024-03-11 |  Magnetic resonance imaging (MRI) is a test that uses magnetic fields and pulses of radio wave energy to image organs and structures in the body. In many cases, an MRI is able to provide more information than X-rays, ultrasounds, or computed tomography (CT).
In an MRI, the part of the body being scanned is placed inside a special machine containing strong magnets. Pictures of MRI scans are digital images that can be saved and stored on a computer for further study. Images can also be viewed remotely. In some cases, contrast agents may be used to show certain structures more clearly. |
