| 目的：探索剪切波弹性模量与核磁共振(MR)对干燥综合征涎腺病变的诊断价值。方法：回顾性分析的63例健康体检者(对照组)、110例干燥综合征涎腺病变患者(观察组)均在2019年3月至2020年10月期间收集,根据观察组患者病情严重程度分为两组,轻度组(n=69)、重度组(n=41),对比三组双侧颌下腺及腮腺杨氏模量均值、T1WI、T2WI、腮腺导管扩张分级、脂肪信号分级,再用ROC曲线分析上述指标单用和八项联合预测价值。结果：重度组、轻度组双侧颌下腺杨氏模量均值、腮腺杨氏模量均值、T1WI、T2WI、脂肪信号分级、腮腺导管扩张分级高于对照组(P＜0.05),经Spearman法分析患病率和病情严重程度与腮腺导管扩张分级、脂肪信号分级、T1WI、T2WI、双侧杨氏模量均值均呈正相关性；经ROC曲线分析,八项联合预测干燥综合征涎腺病变的AUC为0.973,早期预测准确性高。结论：MR、剪切波弹性模量对干燥综合征涎腺病变均具有一定诊断价值,但两者联合预测更好降低误诊率。 |

| Abstract: |
| Objective: To explore the diagnostic value of shear wave elastic modulus and MR for salivary gland lesions in Sjogren"s syndrome. Methods: A retrospective analysis of 63 healthy medical examiners (control group) and 110 patients with Sjogren’s syndrome salivary gland lesions (observation group) were collected from March 2019 to October 2020. The severity of the disease in the observation group was divided into Two groups, mild group (n=69), severe group (n=41), compare the three groups of bilateral submandibular and parotid Young"s modulus mean, T1WI, T2WI, parotid duct dilatation grade, fat signal grade, and ROC Curve analysis of the above-mentioned indicators single-use and eight-item joint forecast value. Results: The average Young"s modulus of the bilateral submandibular glands, the average Young"s modulus of the parotid gland, T1WI, T2WI, fat signal classification, and parotid duct dilatation classification were higher in the severe group and mild group than the control group (P<0.05), analyzed by Spearman method The prevalence and severity of the disease are positively correlated with the parotid duct dilatation grade, fat signal grade, T1WI, T2WI, and bilateral Young"s modulus mean; through ROC curve analysis, the eight items jointly predict the AUC of Sjogren’s syndrome salivary gland lesions It is 0.973, the early prediction accuracy is high. Conclusion: Both MR and shear wave elastic modulus have certain diagnostic value for Sjogren’s syndrome salivary gland lesions, but the combination of the two predicts better and reduces the misdiagnosis rate. |
