Imaging has been increasingly recognized as a powerful tool for diagnosing Alzheimer's disease (AD). Magnetic resonance imaging (MRI) is advantageous over other imaging modalities due to its non-invasiveness and multi-parametric capabilities. In addition to the morphological assessment, several new MR imaging approaches have shown potential for improved AD diagnosis. This paper focuses on two of these advanced MRI-based approaches: diffusion-weighted imaging and arterial spin labeling.
