BACKGROUND
Using Otoplan software, it is possible to measure the cochlea before cochlear implant surgery. Until now, computed tomography (CT) of the cochlea has been necessary for this purpose. The aim of this study was to find out whether measuring the cochlea with magnetic resonance imaging (MRI) using Otoplan is possible with the same accuracy.
METHODS
The cochlea of 44 patients of the local cochlear implant centre was measured by Otoplan using high-resolution CT-bone and MRI images, and the determined lengths were compared.
RESULTS
No significant difference was found between the cochlear lengths measured, regardless of whether the length measurement was based on a CT or an MRI data set.
CONCLUSION
For the determination of cochlear length prior to cochlear implant surgery, MRI images are just as suitable as CT images, therefore CT is not mandatory for length measurement by Otoplan, which could reduce the patient's radiation exposure.
背景
使用 Otoplan 软件，可以在人工耳蜗植入手术前对耳蜗进行测量。到目前为止，这一目的需要进行耳蜗的计算机断层扫描（CT）。本研究的目的是确定使用 Otoplan 通过磁共振成像（MRI）测量耳蜗是否具有相同的准确性。
方法
使用高分辨率 CT 骨和 MRI 图像，通过 Otoplan 对当地人工耳蜗植入中心的 44 名患者的耳蜗进行了测量，并比较了确定的长度。
结果
无论长度测量是基于 CT 数据集还是 MRI 数据集，所测量的耳蜗长度均无显著差异。
结论
对于人工耳蜗植入术前耳蜗长度的确定，MRI 图像与 CT 图像一样适用，因此，Otoplan 的长度测量不需要 CT，这可以减少患者的辐射暴露。
