Longitudinal QSM: Enhancing consistency of multiple time point susceptibility maps via simultaneous reconstruction

arXiv:2605.01819v1 Announce Type: new Abstract: Quantitative susceptibility mapping (QSM) has been increasingly applied in longitudinal studies of neurodegenerative diseases and aging to assess temporal alterations in brain iron and myelin. The accuracy of such investigations depends on the repeatability and sensitivity of measurements. However, the ill-posed nature of the QSM processing steps makes the reconstruction vulnerable to background field changes, head orientation changes, noise, and i...
