Abstract

Purpose: This study aimed to explore the ability of fusion images of non-echo planar diffusion-weighted magnetic resonance imaging (non-EPI-DWI MRI) and computed tomography (CT) to accurately locate cholesteatoma and plan the surgical approach.

Methods: In the first part, 41 patients were included. Their CT images and non-EPI DWMRI images were fused. The scope of cholesteatoma in the fusion image was compared with that in the surgical video to evaluate the capability to locate cholesteatoma. A total of 229 patients were included in the second part, and they were divided into 2 groups. We chose the surgical approach for the CT group and the fusion group, and compared the accuracy of surgical approaches in the CT group and the fusion group using the surgical records.

Results: The location of cholesteatoma shown in the fusion images was almost identical to that observed during the operation (kappa = .862). The overall specificity and sensitivity of the fusion images in locating cholesteatoma were 94.12% and 93.06%, respectively. The accuracy of surgical approach selection based on the fusion images (99.02%) was higher than that of surgical approach selection based on the CT images (85.83%).

Conclusion: It is recommended that the fusion images be used to locate the range of the cholesteatoma before operation.

根据非回波平面弥散加权核磁共振成像和 CT 的融合图像选择中耳胆脂瘤的手术方法

目的：本研究旨在探讨非回波平面弥散加权磁共振成像（non-EPI-DWI MRI）和计算机断层扫描（CT）的融合图像在准确定位胆脂瘤和规划手术方法方面的能力：方法：第一部分包括41名患者。方法：第一部分共纳入 41 例患者，将他们的 CT 图像和非EPI DWMRI 图像进行融合。将融合图像中胆脂瘤的范围与手术视频中的范围进行比较，以评估定位胆脂瘤的能力。第二部分共纳入了 229 名患者，并将他们分为两组。我们为 CT 组和融合组选择了手术方法，并通过手术记录比较了 CT 组和融合组手术方法的准确性：结果：融合图像显示的胆脂瘤位置与手术中观察到的位置基本一致（kappa = .862）。融合图像在确定胆脂瘤位置方面的总体特异性和敏感性分别为 94.12% 和 93.06%。根据融合图像选择手术方法的准确率（99.02%）高于根据 CT 图像选择手术方法的准确率（85.83%）：结论：建议在手术前使用融合图像定位胆脂瘤的范围。

期刊介绍： The Annals of Otology, Rhinology & Laryngology publishes original manuscripts of clinical and research importance in otolaryngology–head and neck medicine and surgery, otology, neurotology, bronchoesophagology, laryngology, rhinology, head and neck oncology and surgery, plastic and reconstructive surgery, pediatric otolaryngology, audiology, and speech pathology. In-depth studies (supplements), papers of historical interest, and reviews of computer software and applications in otolaryngology are also published, as well as imaging, pathology, and clinicopathology studies, book reviews, and letters to the editor. AOR is the official journal of the American Broncho-Esophagological Association.
