Our aim was to determine whether MRI reliably shows pathology in patients with active otosclerosis (otospongiosis). We studied five patients with clinical and audiometric signs of this disorder and positive findings on high-resolution CT and tympanocochlear scintigraphy. Contrast enhancement of otospongiotic lesions was found in all affected ears, and could be topographically related to demineralised otospongiotic foci on CT. In lesions in the lateral wall of the labyrinth MRI sometimes showed the pathology better than CT, where partial-volume effects could be troublesome.
我们的目的是确定MRI是否能可靠地显示活动性耳硬化症（耳海绵化症）患者的病变情况。我们研究了5例有该疾病临床和听力体征且高分辨率CT及鼓室耳蜗闪烁扫描有阳性发现的患者。在所有患耳中均发现耳海绵化病变有对比增强，且在CT上其在地形学上与脱矿的耳海绵化灶相关。在迷路侧壁的病变中，MRI有时比CT能更好地显示病变情况，因为CT的部分容积效应可能会造成麻烦。
