我们检查了三名双侧腮腺同时患有多发性 Warthin 肿瘤的患者，并描述了使用动态 MRI 的价值。对比度指数（CI 曲线）的时间进程是根据动态序列计算的。 Warthin 肿瘤在 T1WI 上显示中等信号强度，在 T2WI 上显示不均匀的高和中等信号强度，在 Gd-T1WI 上显示轻微增强。 Warthin 肿瘤的 CI 曲线显示出特定的发现。每个病变的 CI 曲线显示出相同的模式。仅使用 T1、T2 和 Gd-T1WI 上的 MR 图像很难将肿块诊断为 Warthin 肿瘤。动态 MRI 可以将 Warthin 肿瘤与除嗜酸细胞瘤以外的其他可能的肿瘤区分开来。因此，推荐使用动态MRI作为腮腺多发同步病变沃辛肿瘤的诊断方法。 (C) 2002 Elsevier Science Ltd. 保留所有权利。
We examined three patients with multiple synchronous Warthin's tumors in the bilateral parotid and described the value of using dynamic MRI. The time course of the contrast index (CI curves) was calculated from a dynamic series. Warthin's tumors showed intermediate signal intensity on T1WI, heterogeneous high and intermediate signal intensity on T2WI and a slight enhancement on Gd-T1WI. Warthin's tumors of CI curves showed specific findings. CI curves in each lesion showed the same pattern. It was difficult to diagnose masses as Warthin's tumors using only MR images on T1, T2 and Gd-T1WI. Dynamic MRI can distinguish Warthin's tumors from other possible tumors except for oncocytoma. Therefore, the use of dynamic MRI is recommended as a diagnostic method for Warthin's tumors in multiple synchronous lesions of the parotid gland. (C) 2002 Elsevier Science Ltd. All rights reserved.
