-With Brain MRI in particular, there are quite a few sequence variations that may be encountered or substituted. These sequence variations may provide the same or similar image contrast, but have different SNR, be 3D vs 2D, or run times. As with all things in MRI, there are trade-offs with each sequence choice that will be noted below. The different sequences will be categorized by their image contrast. Please note that some sequences will be vendor or software level specific, so may not be available on every scanner.+With Brain MRI in particular, there are quite a few sequence variations that may be encountered or substituted. These different sequences may provide the same or similar image contrast, but have different SNR, be 3D vs 2D, or have additional special properties. As with all things in MRI, there are trade-offs and pros/cons with each sequence choice that will be noted below. The different sequences will be categorized by their image contrast.
