摘　　要：目的:研究磁共振自旋回波-回波平面成像-弥散加权成像(SE-EPI-DWI)技术在中耳胆脂瘤及其常见颅脑并发症诊断中的应用。方法:选择医院收治的疑似中耳胆脂瘤并均经病理检查的82例患者,根据病理检查结果将其分为胆脂瘤组(55例)和非胆脂瘤组(27例)。患者术前均行耳部常规MRI及SE-EPI-DWI检查,分析SE-EPI-DWI诊断中耳胆脂瘤与病理结果的差异,采用受试者工作特征(ROC)曲线分析SE-EPI-DWI成像技术在中耳胆脂瘤诊断的价值,以及并发症情况。结果:两组患者的年龄、性别,耳内流脓间歇、分泌物性质、鼓室导抗图及听力损失情况差异无统计学意义。82例患者SE-EPI-DWI诊断胆脂瘤的准确率为83.64%,非胆脂瘤的准确率为74.07%。SE-EPI-DWI诊断胆脂瘤ROC曲线下面积(AUC)为0.795。经病理检查,胆脂瘤组的55例患者中有46例术中证实合并存在颅内并发症,部分患者合并多个并发症。结论:SE-EPI-DWI检查图像信噪比高,诊断中耳胆脂瘤的灵敏度高,特异度强,对颈部间隙脓肿、耳后骨膜下脓肿、硬膜外脓肿及脑脓肿等具有较好的诊断能力。Objective:To explore the application of nuclear magnetic spin echo-echo planar imaging-diffusion weighted imaging(SE-EPI-DWI)technique in the diagnoses of middle ear cholesteatoma and its common complications in brain.Methods:82 patients with suspected middle ear cholesteatoma who underwent pathological examination were selected and they were divided into cholesteatoma group(55 cases)and non-cholesteatoma group(27 cases)according to the results of pathological examination.All patients underwent routine magnetic resonance imaging(MRI)and SE-EPI-DWI examination before operation.And the differences of middle ear cholesteatoma between SE-EPI-DWI diagnosis and pathologic results were analyzed.And the receiver operating characteristic(ROC)curve was adopted to analyze the value of SE-EPI-DWI technique in the diagnosis of cholesteatoma,and to analyze the situation of the complications of middle ear cholesteatoma.Results:There were no significant differences in age,gender,interval of suppuration within ear,nature of secretion,tympanogram and hearing loss between the two groups.The accuracy of SE-EPI-DWI in diagnosing cholesteatoma and non-cholesteatoma was 83.64%and 74.07%for 82 patients,respectively.The area under curve(AUC)of ROC curve of SE-EPI-DWI was 0.795 in diagnosing cholesteatoma.46 cases of 55 patients in cholesteatoma group were confirmed with intracranial complications according to pathological examination,and some of patients merged multiple complications.Conclusion:The images of SE-EPI-DWI examination has high signal-to-noise ratio,high sensitivity and strong specificity in the diagnosis of cholesteatoma,and it has favorable diagnostic ability for intracranial complications such as interval abscess at the separation of neck,retroauricular subperiosteal abscess,epidural abscess and brain abscess.
