Example apparatus and methods reconstruct under-sampled 3D data associated with nuclear magnetic resonance (NMR) signals acquired from the volume using a 3D through-time non-Cartesian generalized auto-calibrating partially parallel acquisitions (GRAPPA) approach. The NMR signals are produced in response to a 3D non-Cartesian (e.g., stack-of-spirals) pulse sequence. Example apparatus and methods produce a quantified value for T1 relaxation, T2 relaxation, diffusion, or other NMR parameters in the volume from signal intensities in the data. The quantified value may describe, for example, a perfusion parameter, a blood flow parameter, a blood volume parameter, or other value. Greater precision is achieved for the NMR parameter in the volume as a result of the quantization performed on data acquired with greater spatial resolution and temporal resolution."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Quantifying magnetic resonance parameters","description":"Example apparatus and methods provide improved spatial and temporal resolution over conventional magnetic resonance imaging (MRI) for a large (e.g., 500 cm3) three dimensional (3D) volume.
