To study the use of three-dimensional (3D) rendering of T2-weighted magnetic resonance imaging (MRI) images into 3D models of the inner ear in the preoperative assessment for cochlear implantation.
A retrospective case review of cochlear implant candidates undergoing preoperative imaging studies to determine their suitability for surgical implantation.
A tertiary referral center for the northwest area of England with an established 10-year-old program in cochlear implantation.
Selected adult and pediatric patients referred for cochlear implant assessment from 1996 to 1998, who underwent computerized tomography (CT) and MRI studies.
Diagnostic imaging modality to assess the structure and patency of the inner ear.
To see how detailed anatomic information provided by these 3D models influenced surgical decisions.
Four case studies (with their 3D models) are presented to illustrate different points of interest.
These 3D models provide the implanting surgeon with precise, detailed, and easily interpretable information about the cochlea, which help to guide surgical implantation, or in certain cases, to decide against attempting surgery in the presence of unfavorable anatomic factors.
研究在人工耳蜗植入术前评估中，将T2加权磁共振成像（MRI）图像的三维（3D）渲染转换为内耳3D模型的应用。
对接受术前影像学检查以确定其是否适合手术植入的人工耳蜗植入候选者进行回顾性病例分析。
英格兰西北部的一家三级转诊中心，该中心有一个已开展10年的人工耳蜗植入项目。
选取1996年至1998年间因人工耳蜗植入评估而转诊的成年和儿科患者，他们接受了计算机断层扫描（CT）和MRI检查。
采用诊断性成像方式评估内耳的结构和通畅性。
观察这些3D模型提供的详细解剖信息如何影响手术决策。
展示了四个病例研究（及其3D模型）以说明不同的关注点。
这些3D模型为植入外科医生提供了有关耳蜗的精确、详细且易于解读的信息，有助于指导手术植入，或者在某些情况下，在存在不利解剖因素时决定不尝试手术。
