สรุป	Diffusion Tensor Imaging Tractography (DTI tractography) is a non-invasive neuroimaging technique that maps white matter fiber bundles in the brain by tracking the three-dimensional diffusion of water molecules along axons. Pioneered by Basser, Mori, and Conturo in the 1990s, DTI tractography reveals the structural connectivity of the brain, enabling visualization of major pathways (corpus callosum, arcuate fasciculus, corticospinal tract) and assessment of fiber integrity. It is widely used in neurosurgical planning, neurological disease assessment, and brain connectivity research.	Magnetic Resonance Elastography (MRE) is a non-invasive imaging technique that measures tissue stiffness by encoding the motion of acoustic shear waves into MRI signal and calculating the elastic modulus from wave propagation patterns. Developed by Muthupillai and colleagues in 1995, MRE enables quantitative assessment of tissue mechanics, particularly useful for diagnosing liver fibrosis, cardiac dysfunction, and neurological diseases. It has emerged as a non-invasive alternative to biopsy for staging hepatic fibrosis and is expanding into other organ systems.
