與Oticon Medical Sentio Ti經皮骨導聽力植入體相關之磁振造影偽影

// Magnetic Resonance Imaging Artifact Associated With the Oticon Medical Sentio Ti Transcutaneous Bone Conduction Hearing Implant

本研究評估Oticon Medical Sentio Ti骨導植入物在屍體頭顱MRI中所造成的影像失真與雜訊｜結果顯示植入側顳骨區域存在明顯的無法診斷的變形，即使應用金屬雜訊抑制技術仍無法改善｜超高頻T1加速掃描序列表現最佳，但仍無法提供可診斷影像，這對植入患者的膽脂瘤等MRI監測帶來挑戰，影響聽力治療決策。

// This study assessed MRI artifact and image distortion caused by the Oticon Medical Sentio Ti bone conduction implant in a cadaveric head. MRI scans using standard and metal artifact reduction techniques showed significant nondiagnostic distortion in the ipsilateral temporal bone regions after implantation. The axial T1 turbo spin echo high bandwidth sequence reduced artifacts best but still failed to produce diagnostic images on the implanted side. These findings highlight challenges in MRI surveillance, especially for cholesteatoma, in patients with this implant, impacting clinical decisions for hearing loss treatment.
