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.
