The pulse sequence used for in vivo studies. The readout part consists of a single-shot spiral-in and an interleaved variable-density spiral-out acquisition. The spiral-in readout gives a low-resolution navigator image that can be used to estimate the amount of gross patient motion for each shot. In addition the navigator is used for coil sensitivity estimation, nonlinear phase correction, and the elimination of irreversibly corrupted k-space data. The variable-density spiral out readout makes up one interleaf of the final k-space data to form a high-resolution diffusion-weighted image.
