We present a method to incorporate isotropic diffusion
weighting into a twice-refocused spin-echo (TRSE)
preparation with a single image acquisition. The
gradient design is optimized to compensate for eddy
current effects of a given time constant and to minimize
the TE. By doing this, images with isotropic diffusion
contrast are obtained in three times faster than the
standard acquisition procedures while also preserving
edge sharpness and geometric integrity.
