Abstract: A magnetic resonance (MR) dynamically imaging method is provided. The method includes acquiring a functional MR dataset including frames of k-space datasets, while a functional stimulus is applied to the subject. Acquiring the functional MR dataset includes, acquiring a frame of k-space datasets by setting an orientation as an initial angle, and acquiring a free induction decay (FID) dataset. Acquiring an FID dataset includes applying a sequence of gradients, each gradient of the sequence corresponding to a k-space spoke, wherein the sequence of k-space spokes define a k-space segment having the orientation in a 3D k-space volume. Acquiring a frame of k-space datasets also includes acquiring a gradient echo dataset corresponding to the FID dataset, and updating the orientation as golden angles. The method also includes generating anatomical MR images and functional images based on the functional MR dataset.

Abstract: A method for imaging a substrate and product over time is provided. The substrate and product are magnetically tagged with at least one magnetic gradient where magnetically tagging provides a tag-dependent signal phase for the substrate and a different tag-dependent signal phase for the product. At least one readout of magnetically tagged substrate and product is provided over time. The tag-dependent signal phase is used to determine product that has been transformed from magnetically tagged substrate and substrate that has been transformed from magnetically tagged product over time.

Abstract: In imaging a first species having a short T2 magnetic resonance parameter in the presence of a second and third species having longer T2 parameters, a method of suppressing signals from the longer T2 species comprises the steps of: a) applying a RF saturation pulse with multiple suppression bands for the second and third species to excite nuclei spins of the longer T2 species with the magnitude of the RF pulse being sufficiently low so as not to excite nuclei spins of the short T2 species, the RF saturation pulse being sufficiently long to rotate the longer T2 species nuclei spins into a transverse plane, and b) dephasing the longer T2 species nuclei spins in the transverse plane. An imaging pulse sequence is then applied to image the short T2 species.
