A generalized replacement for 'efgre3d.e', this sequence provides the most common gradient-recalled echo (GRE, as opposed to spin-echo) image contrasts. In addition to using GE's ARC for parallel imaging, it's also possible to do Poisson sampling for compressed-sensing reconstructions.
Used for anything requiring GRE contrasts with generally better flexibility compared to the product sequence.
mm4dflow (vascular phase-contrast)
The original 4D-Flow, this sequence works in both 2D and 3D to acquire phase-contrast flow data in either 1 or 3 flow directions. Generally the sequence is run in a gated-mode to provide temporal resolution, but it can be run non-gated for constant flow phantoms. The reconstructions are run automatically and the resulting images are automatically sent to Arterys for visualization.
