This study employed a 3-D density adapted projection reconstruction sequence, which samples a rectangular cuboid. It was found to attain a full anisotropic resolution and FOV. ²³Na-MRI of the human calf muscles and knee cartilage was conducted using a 7-Tesla whole body MR system with high in-plane resolution. The newly implemented sequence allowed for anisotropic FOVs and resolutions. All in all, it provided a better performance than spherical k-space sampling.
