An MRI (Magnetic Resonance Imaging) scan can provide a three-dimensional, high-resolution image of the brain, making it the best choice for examining brain structure in individuals with Alzheimer's Disease. CT scan (A) may also provide an image, but with lower resolution and less detail than an MRI. fMRI (C) and EEG (D) are used to examine brain function, rather than structure, and may not provide the same level of detail necessary for examining the physical progression of Alzheimer's Disease.
