摘要
目的探讨内耳磁共振水成像在内耳病变诊断中的应用价值。方法选取2014年2月至2016年10月于黑龙江省医院磁共振室行内耳磁共振水成像的患者共94例为研究对象，患者具备手术资料、CT、MRI水成像资料，以手术金标准资料作为依据，分析CT、MRI水成像在诊断内耳病变的灵敏度、特异度、准确度、阳性预测值和阴性预测值，并比较两种检查方式之间的统计学差异。结果MRI水成像诊断内耳各疾病的灵敏度、特异度、阳性预测值和阴性预测值均高于CT，但均不具有统计学意义（P〉0．05），在对前庭导水管异常（χ2=7．265，P=0．015）、耳蜗畸形（χ2=5．042，P=0．028）和耳蜗纤维化（χ2=5．492，P=0．027）疾病的诊断准确度比较中，差异具有统计学意义（P〈0．05）。结论MRI水成像可有效提供耳道、内膜等耳内部器官的信息，可为临床诊断提供有利依据，值得在工作中推广应用。
Objective To discuss the clinical value of magnetic resonance imaging in the diagnosis of inner ear lesion. Methods 94 patients who took magnetic resonance imaging water imaging were selected as study subjects from February 2014 to October 2016 in Heilongjiang Province Hospital. All the patients had surgical data, CT, MRI water imaging data. Based on the standard data of surgery gold, analyzed the sensitivity, specificity, accuracy, positive predictive value and negative predictive value of CT and MRI in the diagnosis of inner ear lesions, compared the statistical differences between the two methods of examination. Results The sensitivity, specificity, positive predictive value and negative predictive value of MRI water imaging in diagnosis of inner ear were higher than CT, but the differences were no statistically significant （all P 〉 0.05 ）. In the case of abnormal vestibular aqueduct（ χ2 = 7. 265, P = 0.015 ）, cochlear deformity （ χ2 = 5. 042, P = 0. 028 ）, diagnostic accuracy of cochlear fibrosis （ χ2 = 5. 492, P = 0. 027）, the differences were statistically significant （ all P 〈 0.05 ）. Conclusion MRI water imaging can effectively provide the information of ear canal, endometrial and other internal organs, can provide a favorable clinical diagnosis, it is worth to promote the application in the clinical work.
