Results Anatomic structures of membranous labyrinth and internal auditory meatus were well demonstrated in three-dimensional reconstructed images of MIP in all volunteers. All three semicircular ducts, utricle, saccule, cochlear duct and internal auditory meatus produced high intensity signal. 结果MIP三维重建能满意显示两侧内耳膜迷路及内耳道的解剖结构,其中3个膜半规管、椭圆囊、球囊、蜗管及内耳道呈高信号。
The natural cavity and foramen in the temporal bone, such as the external auditory canal, tympanic cavity, internal auditory canal, vestibular duct, cochlear duct and the mastoid process segment of facial nerve, became narrowed due to fibrous dysplasia. 骨纤维异常增殖症可导致颞骨的自然腔隙、孔道狭窄,如外耳道、鼓室腔、内听道、前庭导水管、耳蜗导水管及面神经乳突段骨管;
