Patent ID: 10330760

Abstract:
An MRI apparatus includes: a data processor configured to acquire a first set of T2-weighted imaging data and a second set of T2-weighted imaging data; a pulse sequence controller configured to generate a pulse sequence and apply the generated pulse sequence to a gradient coil assembly and RF coil assembly, the generated pulse sequence including: T2-preparation modules and associated imaging modules to acquire the first set of T2-weighted imaging data, and a saturation pulse sequence and an associated saturation imaging module to acquire the second set of T2-weighted imaging data; a curve fitter configured to apply the first and second sets of T2-weighted imaging data to a three-parameter model for T2 decay, to determine a T2 value at a plurality of locations; and an image processor configured to generate a T2 map of the object based on the T2 value determined at the plurality of locations.
