Abstract:
In a magnetic resonance method and apparatus, deficiencies in conventional masking in quantitative susceptibility mapping (QSM) are addressed by the inclusion of an additional step in the conventional QSM post-processing pipeline. In this additional step, atlas-based segmentation techniques, which have been developed for morphological applications such as T1w MPRAGE are used in order to provide the mask. This mask is then fed to the remainder of the QSM post-processing pipeline.

Claim (Index 11):
A non-transitory, computer-readable data storage medium encoded with programming instructions, said storage medium being loaded into a computer of a magnetic resonance (MR) apparatus comprising an MR data acquisition scanner having a radio-frequency (RF) reception coil combination, said programming instructions causing said computer to:\n operate said MR data acquisition scanner in order to execute a gradient echo MR data acquisition sequence, so as to acquire MR data from a current subject during an echo of said gradient echo MR data acquisition sequence using said RF reception coil combination of said MR data acquisition scanner; execute an MR image reconstruction algorithm in order to reconstruct an MR image of the current subject; execute a QSM mapping algorithm in which said at least one MR image of the current subject is used as an input, said QSM mapping algorithm including a masking step in order to generate a mask that is used in subsequent steps of said QSM mapping algorithm in order to generate a magnetic susceptibility map that represents a spatial distribution of magnetic susceptibility values of tissue in the current subject; execute said masking step by accessing an atlas comprising a plurality of MR images respectively for a plurality of subjects, wherein each of said MR images in said atlas was generated from a same echo in a gradient echo MR data acquisition sequence as said echo during which said MR data were acquired from said current subject, and combining said MR images from said atlas to produce said mask; and generate a data file comprising said magnetic susceptibility map and make the data file available from the processor in electronic form.
