WebHalf-Fourier acquisition single-shot turbo spin echo (HASTE) imaging is a single-shot echo-planar fast spin echo sequence for high-resolution T2 images specific to Siemens (but other MRI vendors provide similar versions). HASTE uses phase-conjugate symmetry to take advantage of “mirror-image” properties in k-space.
