Ultra-short echo time quantitative susceptibility mapping (QSM) is a promising tool for the study of tissues with short relaxation times. At ultra-high field, the reconstruction of quality phase images is challenging because of the absence of a reference coil. We propose the use of selective channel combination of phase-offset-corrected signal phase data for ultra-short echo time QSM. We compared our findings against an established channel combination method. Qualitative and quantitative analyses of combined phase and QSM images were performed at three echo times. Selective combination of individual channel phase images results in improved ultra-short echo time susceptibility maps.
