| 摘 要： | 目的 探讨磁共振仿真内镜(MRVE)显示内耳系统的可行性及其正常解剖学表现。资料与方法 对53例健康受试者106只内耳行3D FASE重T2WI横断面成像扫描。原始图像传至在网工作站进行图像后处理。在工作站行透视容积再现(PVR)成像,利用仿真内镜(VE)对内耳进行腔内结构观察。结果 MRVE可详细、明确显示内耳腔内的解剖结构,而且检查过程可以制成录像反复、多方位观察,是一种方便、易行、灵活的无创性检查手段。结论 MRVE可用于内耳膜迷路的腔内结构研究,为MRI发现内耳疾病打下了坚实的基础。

| Abstract: | Objective To discuss the feasibility of displaying inner ear with MR virtual endoscopy (MRVE) and to study the anatomy of inner ear on MRVE.Materials and Methods 3D FASE heavily T2-weighted axial scanning was carried out in 53 healthy volunteers (total 106 inner ears). The original images were transferred to an online workstation where post-processing of the images and perspective volume rendering (PVR) reconstruction were conducted. With MRVE the inner ear structures were observed. Results MRVE could well display the structures of inner ear from different angles and the pictures could be recorded. Conclusion MRVE is a simple and noninvasive technique, which is very valuable in observing the inner ear structures, especially the membranous labyrinth. |
