3.0T磁共振腮腺管水成像在腮腺疾病中的应用

目的：分析3.0T磁共振腮腺管水成像技术（MRS）在腮腺疾病诊断及治疗中的应用价值。方法选择我院收治的腮腺疾病患者33例，采用常规核磁共振（MRI）扫描后，采用IR-FSE序列进行 MRS 扫描，并于含服维生素C以后再次进行扫描，评价MRI与MRS扫描结果。结果本组33例患者中，MRI 诊断准确率为97.0%；5例非肿瘤性病变患者中，11例发生导管系统变形；在18例肿瘤性病变患者中，有15例发生导管系统变形；含服维生素C后显示效果明显优于含服前（P ﹤0.05）。结论IR-FSE序列下MRS扫描能够获得良好的腮腺导管成像，且具有无创、操作简便、安全可靠等优点，能够为临床诊断及治疗提供客观、全面的信息。

Clinical application of 3. 0T MR sialography in parotid gland diseases

Objective：To explore clinical application of 3. 0T MR sialography（MRS）in parotid gland diseases value. Methods：In the thirty-three cases of parotid gland disease patients from January,2013 to January,2014 in our hospital, the conventional MRI scans,MRS scans were performed using IR-FSE sequence,and vitamin C with again after the scan. Results：In MRI diagnosis of 33 cases of patients,the accuracy rate was 97% ;in 5 cases of non tumor lesions in patients, 11 cases of ductal system had deformation;in 18 cases of tumor patients,there were 15 cases of catheter system deforma-tion;containing vitamin C display was better than before（P ﹤ 0. 05）. Conclusion：IR-FSE sequence MRS scanning for ob-taining the good image of the parotid duct has the advantages of noninvasiveness and simple operation,which is safe and re-liable,and able to provide objective and comprehensive information for clinical diagnosis and treatment.
