1. Spin density MRI : A magnetic resonance image where the contrast is predominantly dependent on spin density.
2. Diffusion MRI : uses water as contrast .
3. Magnetization Transfer MRI: refers to the transfer of longitudinal magnetization from the hydrogen nuclei of water that have restricted motion ( macromolecules – protein /lipids) to the hydrogen nuclei of water that moves (cytosol) with many degrees of freedom.
4. Fluid attenuated inversion recovery (FLAIR) – Is an inversion recovery protocol with long TI to remove the effects of fluid from the resulting images.
5. Functional MRI – based on changes in blood flow secondary to neural activity
6. Real-time MRI – quick
7. Magnetic resonance angiography- useful to visualize the vasculature using gadolinum contrast .
8. Magnetic resonance gated intracranial CSF dynamics (MR-GILD) – analyze CSF circulatory system dynamics Magnetic resonance spectroscopy
