A type of MRI sequence that uses a gradient magnetic field to oppose the main magnetic field, used for T2*-weighted imaging
Diffusion-weighted (DW) sequence
A type of MRI sequence that measures diffusion coefficients, used for detecting restricted diffusion
T1-weighted (T1w) sequence
A type of MRI sequence that emphasizes hydrogen density and T1 relaxation time, used for brain, spine, and musculoskeletal imaging
T1-weighted vs. T2-weighted sequences
Differences: T1 relaxation time (~1.5-2 s vs. ~50-100 ms), contrast (brighter signal in fat vs. brighter signal in fluid), weighting (T1 vs. T2 relaxation time), applications (brain, spine, and musculoskeletal imaging)
