Answer:

Magnetic resonance imaging (MRI) is a technology that produces 3D images in order to assess brain activity, which is used in the diagnosis, monitoring and treatment of diseases

Explanation:

Magnetic Resonance Imaging (MRI) is a non-invasive method that generates three-dimensional (3D) images which are used for diagnostics and disease monitoring. MRI is useful to distinguish between white and grey matter in the brain, and thereby this technique can be used for the diagnosis of tumors and aneurysms which are caused by weakness in the arterial walls. Moreover, MRI is also useful to analyze the relationship between regions of the brain and cognitive processes by monitoring the neurological-psychophysiological status of an individual.
