Imaging pathology in the internal auditory canal and orbits benefits from techniques such as bSSFP MRI due to its high time efficiency and SNR. Here the geometric solution (GS) is proposed in concert with bSSFP for temporal bone and orbit imaging to circumvent banding and motion artifacts. The GS-bSSFP technique is validated in a cohort of patients scheduled for evaluation of treated vestibular schwannoma. Three blinded neuroradiologists found that GS-bSSFP exceeded comparable techniques in terms of image quality and diagnostic utility.
