Define in brief about the term - MRI

MRI is a more recent development that was initially introduced as a rival to CT. The technique itself is complex, relying on measurement of the response of hydrogen atoms to radio waves in very strong magnetic field. The MRI scanner measures the tiny magnetic fields that the spinning hydrogen atoms produce, and since the density of hydrogen varies in different types of tissue, the scan data can be computer-processed to generate images. The entire brain can be imaged in successive slices, which can be produced in saggital (side), coronal (front) or horisontal transverse planes. The high resolution of MR images (in comparison with CT images) is a major plus point. A second advantage is that participants are not exposed to radiation sources.
