摘　　要：目的分析内耳钆造影MRI前庭导水管显影率与临床应用意义。方法纳入对象的时间节点为:2020年3月至2022年1月,抽取在本院开展内耳钆造影MRI检查的100例患者,对其相关资料做统计、分析,患者具有相应的临床表现,如眩晕、头晕、突发性耳聋、耳鸣等,以有无症状,将100例患者进行分组。观察患者的MRI图像,并与造影前相对比,其中造影后,前庭的导水管区出现高信号者,即为显影,反之为无显影。应用目测评分法,对内耳膜的迷路是否有积水进行测评。对比不同症状下的前庭导水管显影发生率,同时评估前庭导水管显影与膜迷路积水的相关性。结果100例患者中,有26例出现膜迷路积水,有7例患者发现前庭导水管显影。眩晕患者中有6例出现前庭导水管显影,非眩晕患者有25例出现显影,两者相比,P<0.05;突聋患者中,有5例患者出现显影,非突聋患者有4例出现显影,两者相比,P>0.05;耳鸣患者中,有3例出现前庭导水管显影,非耳鸣患者中,有5例出现前庭导水管显影,两者相比,P>0.05。眩晕患者中有10例发现了膜迷路积水,而非眩晕患者中有3例发现了膜迷路积水,两者相比,P<0.05。出现膜迷路积水的患者中,有1例出现前庭导水管显影,无膜迷路积水患者中有7例出现前庭导水管显影,两者相比,P<0.05。由此说明,前庭导水管显影与有无膜迷路积水之间的关系为负相关,r<0。结论在开展内耳钆造影MRI检查中,钆对比剂会进入到前庭导水管,产生相应的显影,对于没有出现前庭导水管显影者,存在较大的膜迷路积水,说明前庭导水管问题的出现,是此发眩晕机制、梅尼埃病的主要环节。Objective To analyze the imaging rate of vestibular aqueduct in inner ear gadolinium angiography and its clinical significance.Methods The time nodes of the included subjects were as follows:From March 2020 to January 2022,100 patients who underwent inner ear gadolinium contrast MRI examination in our hospital were selected,and their relevant data were counted and analyzed.The patients had corresponding clinical manifestations.Such as vertigo,dizziness,sudden deafness,tinnitus,etc.,100 patients were divided into groups according to the symptoms.The MRI images of the patients were observed and compared with those before angiography.After angiography,those with high signal in the aqueduct of the vestibule were bullied,that is,developing,and vice versa.The visual scoring method was used to evaluate whether there was hydrops in the labyrinth of the inner eardrum.The incidence of vestibular aqueduct imaging under different symptoms was compared,and the correlation between vestibular aqueduct imaging and membranous hydrops was evaluated.Results Among the 100 patients,26 had membranous hydrops and 7 had vestibular aqueduct imaging.The vestibular aqueduct was visualized in 6 patients with vertigo,and in 25 patients without vertigo,compared with the two,P<0.05;among the patients with sudden deafness,5 patients had imaging,and 4 patients with non-sudden deafness had imaging.In the tinnitus patients,there were 3 cases of vestibular aqueduct imaging,and 5 cases of non-tinnitus patients had vestibular aqueduct imaging,compared with the two,P>0.05.Membranous hydrops was found in 10 patients with vertigo,and in 3 patients without vertigo,P<0.05.Among the wills with membranous hydrops,1 case had vestibular aqueduct imaging,and 7 cases of non-membranous hydrops had vestibular aqueduct imaging,P<0.05.This shows that the relationship between vestibular aqueduct imaging and membraneless labyrinthine hydrops is negative correlation,r<0.Conclusion During the inner ear gadolinium contrast MRI examination,the gadolinium contrast agent w
