【摘要】：目的评价DWI及动态增强MRI鉴别诊断舌良恶性病变的价值。方法对75例经病理确诊的舌部病变患者行DWI和动态增强MRI。测量并比较舌良恶性病变病灶ADC值,绘制ROC曲线分析ADC值诊断舌恶性肿瘤效能;比较舌良恶性病变时间-信号强度曲线(TIC)分型差异。结果舌恶性病变的ADC值[(1.12±0.21)×10-3 mm2/s]明显低于良性病变[(1.84±0.47)×10-3 mm2/s,P0.001);以ADC值1.30×10-3 mm2/s为阈值,诊断舌恶性病变的敏感度、特异度和准确率分别为90.70%、93.75%和92.00%,ROC曲线下面积为0.957。良性病变(除外8例囊肿)中19例(19/24,79.17%)TIC为Ⅲ型,5例(5/24,20.83%)为Ⅱ型;恶性病变中39例(39/43,90.70%)TIC为Ⅰ型,4例(4/43,9.30%)为Ⅱ型。结论舌良恶性病变DWI和动态增强MRI具有不同特征,ADC值和TIC曲线有助于鉴别诊断两者。
[Abstract]:Objective to evaluate the value of DWI and dynamic enhanced MRI in differential diagnosis of benign and malignant lesions of tongue. Methods DWI and dynamic enhanced MRI. were performed in 75 patients with pathological diagnosis of tongue lesions. The ADC values of benign and malignant lesions of tongue were measured and compared, and the ROC curve was drawn to analyze the diagnostic efficacy of ADC values in the diagnosis of tongue malignant tumors, and the time-signal intensity curve of benign and malignant lesions of tongue was compared with the difference of (TIC) classification. Results the ADC value in malignant lesions of tongue [(1.12 卤0.21) 脳 10 ~ (3) mm2/s] was significantly lower than that in benign lesions [(1.84 卤0.47) 脳 10 ~ (3) mm2/s,P0.001]. The sensitivity, specificity and accuracy of the diagnosis of tongue malignant lesions were 90.70%, 93.75% and 92.00%, respectively, and the area under the curve was 0.957 using the ADC value of 1.30 脳 10 ~ 3 mm2/s as the threshold value, and the sensitivity, specificity and accuracy were 90.70%, 93.75% and 92.0% respectively. Among the benign lesions (except 8 cysts), 19 (19 / 24, 79.17%) showed TIC type 鈪，
