Structure I (T₁, T₂, ultra-high field)
The basics of MRI will be covered, including T₁, T₂, and T₂* contrast mechanisms, optimization of sensitivity and contrast, and common image artifacts. Additionally, we will demonstrate specialized MRI techniques including fluid-attenuated inversion recovery (FLAIR). Basic anatomical MRI image post-processing techniques will be discussed, including segmentation, co-registration, brain normalization for across-subject comparison, correction of shape distortions due to magnetic field inhomogeneity, quantitative brain morphometric, 3-D rendering, and susceptibility weighted imaging. Examples will include images acquired with 3 and 7 Tesla scanners.
