Keywords: Susceptibility/QSM, Quantitative Susceptibility mapping
Motivation: SWI is a widely acquired protocol in clinic and often acquired in an anisotropic resolution (i.e., 0.5×0.5×2 mm3). Whereas QSM, which has been attracting utilities, has been recommended to acquire in 1 mm isotropic resolution.
Goal(s): This study is aimed to propose a resolution translation method so that SWI data can be transformed to QSM reconstruction.
Approach: A super-resolution network was designed to transform complex GRE data, exploiting high in-plane resolution information while sustaining down-sampling consistency.
Results: The proposed method successfully generated high-quality isotropic resolution data for QSM from anisotropic SWI data.
Impact: The proposed resolution translation successfully generated high-quality complex GRE images for the isotropic resolution, resulting in high-quality QSM, outperforming the conventional approaches.
