"Time-resolved angiography with interleaved stochastic trajectories (TWIST) is a 3D time-resolved MR angiography (MRA) sequence - being vendor-specific to Siemens."
"The principle of TWIST lies with special k-space sampling. The centre of k-space holds information about image contrast while the periphery of k-space encodes information on edges and details. The TWIST sequence over-samples central k-space relative to peripheral k-space."
