Meaning of MRI

What Does MRI Mean? (Using MRI Online)

MRI (Magnetic Resonance Imaging) is a technique that uses a magnetic field and radio waves to create detailed images of the organs and tissues within the body. Most MRI machines are large, tube-shaped magnets. When patients lie inside an MRI machine, the magnetic field temporarily realigns hydrogen atoms in the body. The excited hydrogen atoms emit a radio frequency signal which is measured by a receiving coil and this information is interpreted by computer to create images

MRI should not be confused with CAT (Computed Axial Tomography) scan technology. Nowadays referred to simply as CT (Computed Tomography), this method of scanning uses computer-processed combinations of many X-ray images taken from different angles to produce cross-sectional (tomographic) images (virtual 'slices') of specific areas of a scanned object, allowing the user to see inside the object without cutting.

MRI is the investigative tool of choice for neurological cancers, as it is more sensitive than CT for small tumours and offers better visualization. MRI does not use any ionizing radiation, and its use is now generally favoured in preference to CT. With the cost of MRI scanners becoming more competitive, it is likely that MRI will replace CT in the future.
