| 目的 确定MR 成像是否可用于判断涎腺病变的性质,以及其诊断的准确性。方法 对60 例经手术病理证实的病例进行回顾性分析。将10 个MR 表现参数进行逻辑回归分析,确定哪些参数可预测涎腺病变的良、恶性。结果 逻辑回归分析表明:在包括炎症病例的情况下,仅转移( P < 0. 001) 征象可预测病变的性质。而在不包括炎症病例条件下,颈部淋巴结肿大和周围结构侵蚀在预测涎腺恶性病变方面具有显著意义。用转移征象预测恶性病变的准确性为83. 0 %、敏感性为43. 8 %、特异性为100 %;而侵蚀征象预测恶性病变的准确性84. 9 %、敏感性为50 %、特异性为100 %。当应用转移征象和/或侵蚀征象来预测恶性病变时,准确性为92. 5 %、敏感性为75 %、特异性为100 %。结论 颈部淋巴结肿大和周围结构侵蚀在确定恶性涎腺病变方面具有较高的价值。 |

| Objective To evaluate if MR imaging can be used to diagnosis the nature of the salivary gland lesions , and theaccuracy of this modality. Methods Sixty patient s with salivary gland diseases that included 7 cases of inflammatory lesionswere analyzed respectively. All cases were diagnosed pathologically. A logistic regression model was used to determinewhich MR imaging features were significant factor for predicting the lesion being benign or malignant for each patient . Results Logistic regression model analysis in 60 cases revealed that metastasis was only significant MR characteristics for determining a lesion that was benign or malignant ( P < 0. 001) . It s accuracy , sensitivity and specificity for predicting malignan2cy were 97. 7 % , 43. 8 % , 83. 3 % , respectively. However , the analysis in 53 cases (excluding inflammatory cases) demonst rated that metastases ( P < 0. 001) and infilt ration ( P < 0. 001) were significant factors in predicting a malignant lesion , respectively. Their accuracy , sensitivity and specificity for predicting malignancy were 100 % , 43. 8 % , 83. 0 % and 100 % ,50 % , 84. 9 % , respectively. When combining these two predictors to diagnosis malignancy , their accuracy , sensitivity andspecificity could improve to 92. 5 % , 75 % , and 100 %. Conclusion Lymph node swelling and infilt ration of tumor are usefulfactors to differentiate the malignant or benign lesions. |
