Our pilot study has showed that APT-MRI is feasible for
the use in the head and neck (HN) and has potentials for
HN cancer characterization at 3T. However, HN-APT-MRI is
technically challenging due to tissue heterogeneity,
pronounced susceptibility and various motions, which may
potentially compromise the APT quantification in
different scans. To this end, we investigated the
repeatability of HN-APT-MRI on healthy volunteers and
successfully demonstrated that consistent inter-scan APT
contrast could be achieved in major HN tissues. This
study is helpful to establish the HN-APT-MRI
repeatability so as to ensure its reliability for future
clinical use.
