Axial cranial MR scans were performed at both 1.5\u202fT and 3.0\u202fT field strengths using the following sequences: T1-weighted spin-echo (SE), T2-weighted fast spin-echo (FSE), and T2*-weighted gradient-echo (GRE). The maximum dimension of CI artifacts was measured, and the artifact area was quantified using both manual measurement and a deep learning\u2013based automatic segmentation algorithm. The impact of CI artifacts on the visibility of brain anatomy was evaluated by radiologists.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Under both 1.5\u202fT and 3.0\u202fT MR scanning, GRE sequences exhibited significantly larger artifact maximum dimension and area than SE and FSE sequences (\n                      <jats:italic>p<\/jats:italic>\n                      \u202f&amp;lt;\u202f0.05). No significant differences were noted in maximum artifact dimensions between 1.5\u202fT and 3.0\u202fT MR across sequences (\n                      <jats:italic>p<\/jats:italic>\n                      \u202f&amp;gt;\u202f0.05). The difference in artifact area between manual measurement and the deep learning\u2013based automatic segmentation algorithm was not significant on SE sequences (\n                      <jats:italic>p<\/jats:italic>\n                      \u202f=\u202f0.377).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>GRE sequences produced a wider range of CI artifacts than SE and FSE sequences at both 1.5\u202fT and 3.0\u202fT. No significant difference in artifact size was observed between the two field strengths. The artifact areas on SE sequences showed high consistency between manual measurement and the deep learning\u2013based automatic segmentation algorithm. Therefore, SE or FSE sequences should be prioritized over GRE for CI recipients, and both 1.5\u202fT and 3.0\u202fT are clinically feasible.<\/jats:p>\n
