I'd like to learn more about the different types of MRIs.

An MRI is a type of medical imaging technology that uses magnetic fields and radio waves to visualize internal structures in the body. It is used to diagnose a wide range of diseases, including brain tumors, strokes, spinal cord injuries, and other neurological disorders. There are two main types of MRI scans: anatomical (or structural) MRI and functional MRI. Anatomical MRI scans provide detailed images of the brain and other organs, while functional MRI scans show which parts of the brain are active during specific tasks or activities.
