2022年5月9日 · An MRI (magnetic resonance imaging) scan is a test that creates clear images of the structures inside your body using a large magnet, radio waves and a computer. Healthcare providers use MRIs to evaluate, diagnose and monitor several different medical conditions. There are two main types of MRI machines: closed bore and open.

2024年4月25日 · Magnetic resonance imaging (MRI) is a pain-free, noninvasive medical test used to produce two- or three-dimensional images of the structures inside your body using a strong magnetic field and radio waves.

a noninvasive nuclear procedure for imaging tissues of high fat and water content that cannot be seen with other radiologic techniques. The MRI image gives information about the chemical makeup of tissues, thus making it possible to distinguish normal, cancerous, atherosclerotic, and traumatized tissue masses in the image.
