Radial-FSE methods enable high-resolution diffusion-weighted imaging, in two dimensions, without sensitivity to bulk rigid body motion and/or magnetic field inhomogeneity. In the present work, these methods are extended to three dimensions allowing high spatial resolution to be obtained equally in all dimensions while maintaining a high SNR. This technique also allows all regions of the brain to be measured with diffusion tensor imaging, including areas of susceptibility like the inferior temporal and anterior frontal lobes. In addition, the sequence has been cardiac gated to reduce residual non-rigid body motion due to cardiac pulsation.
