MRI : sMRI and DTI - Structural MRI (sMRI)
5 important questions on MRI : sMRI and DTI - Structural MRI (sMRI)
What is he basic idea of sMRI?
(volume of these tissues differ across pathologies, ages, interventions)
Manual segmentation (way of interpreting MRI results)
- Labor intensive work
- requires very good neuroanatomical knowledge
- done manually by a person, not automatic
Voxel-based morphometry (VBM) (way of interpreting MRI results)
- A really neat analysis tool
- compare brains on voxel-by-voxel basis
- identify differences in local composition of brain tissue
- unbiased/objectif manner
- more sensitive for localizing small regional differences in gray or white matter
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
What is Spatial normalization?
- Registration of each MRI scan to the same template image by a number of transformations
- results in Higher-resolution image corrected for global brain shape differences
Example of behavior correlated in sMIR with VBM analysis.
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
