- Structural MRI: This is the most common type and includes T1-weighted and T2-weighted images. It provides detailed images of the brain's anatomy. - Functional MRI (fMRI): This technique measures brain activity by detecting changes in blood flow. It is often used in research to understand brain functions and in clinical settings to map areas of the brain before surgery. - Diffusion Tensor Imaging (DTI): This type of MRI is used to map the diffusion of water molecules in brain tissue, providing insights into the brain's white matter tracts. - Magnetic Resonance Spectroscopy (MRS): MRS measures the concentration of specific metabolites in the brain and can aid in the diagnosis of certain neurological conditions.
